SPOT Football · The manual
How to use this.
You like football. You like having something on the game. You have never used a tool like this. Start here; it is short.
What SPOT is
SPOT is a free tool that prices every NFL game strictly by the numbers, since 1999. Ace is the guy who does the pricing. He does not care who wins; he cares whether the number the book hung is wrong. When it is wrong in your favor he says BET. When it is not, he says PASS, and a pass is a full answer, said at the same volume. Every bet he says he would make goes on a public sheet before kickoff, locks at kickoff, and is graded from the final score. That sheet is the record, and nothing on it is ever edited. It costs nothing and it stays free.
The board and the rail
The front page is the board: every game this week that has a verified line. The rail at the top is the same games in kickoff order, opened on the next kickoff, with last night's final at the left end. Tap a card to walk into the matchup.
Early Look
Later games with posted lines appear in Early Look, with the full kickoff date. This Week follows the same Tuesday-to-Monday football week as the archive; dates and times use your timezone. Games move sections as the week changes. A posted line is not itself an Ace pick. Published early picks appear separately on Ace's card and keep their original date, price and place in the record.
A matchup card
Each card shows five things. Here is one, and what each line means.
Houston Texans AT Kansas City Chiefs
NFL · Sun 4:25 PM · FRESH
KC -3.5 · O/U 47.5 · HOU +160 / KC -190
Wind 14 mph · 61°F
| Sun 4:25 PM | Kickoff. Every stand on this game freezes at this moment. |
|---|---|
| FRESH | Every number came in on time from its source. Anything else and the card stays shut; we do not price a game on stale data. |
| KC -3.5 | The spread, shown for the home side. Kansas City is laying three and a half. |
| O/U 47.5 | The total: points both teams score, added together. |
| HOU +160 / KC -190 | The moneylines: what each side pays to just win the game. |
| Wind 14 mph | Conditions at kickoff, from the forecast. Wind past 15 mph is the one that moves a total. |
Next kickoff
The pill at the top of the page says how many games are on the board and when the next one kicks off. “NEXT · Thu 8:15 PM” means the Thursday game is the next one to lock. When a game is live it says so, with the score.
The week
The line under the rail tells you where the week is. Tuesday the lines go up. Wednesday the stories drop. Thursday and Friday the practice reports land, and who sat out changes the read. Sunday morning Ace's card is up. Monday he closes the books on yesterday. Come back on the day that matters to you.
Ace's Spots
Ace's Spots is his card for the week: the bets he would make, and only those. Most weeks it is short. Some weeks it is empty, and it says so instead of padding.
Early Picks holds published positions for later weeks. A ticket with any later leg stays whole in that section, with each leg's kickoff shown. Moving sections does not create another pick or change its stake. The original pick and a new assessment are shown separately; fresh odds do not mean every injury report or other game detail is available yet. Check the storyline's missing information.
A stand
A stand is one bet Ace says he would make: a side, a total, a moneyline, a teaser or a parlay. It goes on the sheet before kickoff with the date, the time, the number and the price. At kickoff it locks: not the side, not the number, not the price can change after that. When the game is final it is graded from the score, once, and never again.
HOU +3.5 at -108 · 1u · best: DraftKings -108
Houston, getting three and a half, at a price of -108, one unit on it, and DraftKings has the best price on it right now. Published Wednesday 11:40 AM. Locks Sunday 4:25 PM.
Revised, withdrawn, pending
| PENDING | The game has not gone final. Nothing is decided. |
|---|---|
| REVISED | Before kickoff, the line or the price moved and a new stand replaced this one. The old one stays on the sheet and names its replacement. Only the replacement is graded. |
| WITHDRAWN | Before kickoff the stand came off, usually because a starting quarterback changed. It counts as a withdrawal, not a win and not a loss. Nothing replaces it. |
| LOCKED | The game has started. Nothing changes now. |
| WON · LOST · PUSH | Graded from the final score. A push means the game landed on the number and the money comes back. |
Units
The sheet runs a paper bankroll. It started at $10,000 and one unit is $100. Nothing real is bet by SPOT. Every straight stand is one unit flat. The parlay is half a unit, because variance costs extra. Each round robin ticket is a quarter unit. The stakes change only on a monthly review, never mid-week.
The teaser
A teaser moves the spread 6 points in your favor on two games, and you need both to win. The reason teasers exist is that football games land on 3 and 7 more than any other margins. A dog at +2.5 teased to +8.5 crosses both 3 and 7 on the way, and that leg has cashed 75.6% of the time since 1999. A favorite teased down is the weaker leg, 73.1%, and it only makes the ticket when our ratings say the favorite wins by enough.
HOU +2.5 → +8.5 and DEN +1.5 → +7.5, two-team teaser at -120
Each leg cashes about 75.6%. Both together: 57.1%. At -120 the ticket needs to cash 54.5% to break even. 57.1 beats 54.5 by 2.6 wins per 100 tickets. That is a bet at -120. At -140 the ticket needs 58.3%, and 57.1 is short of it. Same legs, pass. The price is the whole bet.
Three dogs on one board make a three-team ticket when a three-team price is on hand: three legs at 75.6% cash together 43.1%, so at +160 the ticket returns about 12 cents on the dollar against 4.7 for the two-team at -120. Ace shops every priced size and leg count and keeps the ticket worth the most per unit; at equal value the smaller ticket wins, because every extra leg multiplies variance.
The leans
Under the tickets, every man at the table leans on every pregame game at no stake: Nicky from the sharp number, Frankie from his own line. A lean shows his side at the board's terms, his edge, his cover probability, and the five answers behind it: my number, the board's number, why they differ, what could make me wrong, and whether the edge is enough. A lean that clears his own bar says so; one that does not is shown anyway, because a lean is an opinion, not a stake. Leans are graded against the closing line and the result the same way stands are, and that record, not anyone's say-so, decides who earns the units.
The parlay
A parlay is two or more moneylines on one ticket; every leg has to win. Ace only builds one from legs where our number beats the price, and he only publishes it when the ticket's price beats the legs' odds multiplied together. Two good legs do not automatically make a good ticket, and the card says so when there is none.
HOU +160 and DEN +135, pays +511
We make Houston 42% and Denver 46%. Together, 19.3%. A +511 ticket needs 16.4% to break even. That gap is 2.9 wins per 100. Half a unit.
The round robin
Take three or more parlay-grade legs and make every pair, and every triple, its own small parlay, a quarter unit each. One leg losing only takes the tickets it sits on; the rest still pay. Same legs, same prices as the parlay, split up so one miss does not zero the play.
Best book
“best: DraftKings -108” names the regulated U.S. book showing the best price on that side right now. Shop it there, or anywhere better. Ten cents of juice is real money over a season.
Reading a line
The spread
KC -3.5 means Kansas City has to win by 4 or more for a bet on them to cash. HOU +3.5 means Houston can lose by 3 or fewer, or win outright, and cash. The minus side is “laying” points; the plus side is “getting” them.
The total
O/U 47.5 is the points both teams score added together. Over cashes at 48 or more. Under cashes at 47 or fewer. Who wins does not matter.
The moneyline
KC -190 / HOU +160 is just who wins. No points given or taken. The favorite costs more; the dog pays more.
The price: -110 and +150
The price is the number after the line, in American odds. A minus number is what you lay to win $100. A plus number is what $100 wins.
| Price | Bet $100 and win | Profit | Has to win this often to break even |
|---|---|---|---|
| -110 | $190.91 back | $90.91 | 52.4% |
| -120 | $183.33 back | $83.33 | 54.5% |
| -150 | $166.67 back | $66.67 | 60.0% |
| +100 | $200 back | $100 | 50.0% |
| +150 | $250 back | $150 | 40.0% |
| +200 | $300 back | $200 | 33.3% |
The last column is the whole game. At -110 you have to win 52.4% of the time just to stay even, and that extra 2.4% is the book's cut: the juice. A bet is only worth making when it wins more often than that column says it has to.
Favorites and dogs
The favorite is the side laying points, or the minus moneyline. The dog is getting points, or the plus moneyline. Neither is the better bet by itself. The only question is whether the number is wrong.
The half point, 3 and 7
A game cannot land on 3.5, so a spread of 3.5 always wins or loses. A spread of 3 can push: if the favorite wins by exactly 3, the money comes back. That is why a half point matters, and why it matters most around 3 and 7. Since 1999, a game lands on exactly 3 about three times as often as its neighbors, and on 7 about twice as often. Getting +3.5 instead of +3 is not a small thing; it is the difference between cashing and pushing on the most common margin in football.
Inside a matchup
Tap a card and you are in the game's world. Top to bottom, here is what you see.
The faceoff, conditions and the ladder
The two helmets, the kickoff, the bell for “ALERTS ABOUT THIS GAME”, the conditions, and the line. Under it, Where to bet it: the ladder, which is every regulated book's price on each side with the best one named. A one-book feed says so instead of dressing up as a ladder. Exchanges and books outside the US are polled for the sharp anchor but never listed here; the best price is always one you can take.
HOU +3.5 · DraftKings -108 · FanDuel -110 · BetMGM +3 -105 · best: DraftKings -108
Three books on Houston. BetMGM is a different number, +3, so it is shown with its line. DraftKings is the best price at +3.5.
The storyline and the receipts
The storyline is the story of the game: the quarterbacks, the last meeting, the practice report, the weather. It is built from a fact sheet, and every paragraph carries a receipt. Tap RECEIPT under a paragraph and you see the exact facts it rests on, each with the informant who brought it; tap a fact and it opens in its place on the whole sheet. What we don't know yet lists the gaps out loud, so a missing fact is never a guess. HEAR THE STORY has Ace read it in his own voice. The story never tells you what to bet. The call comes from the number, below.
The wager form
Enter the bet you're looking at, exactly as your book shows it, and Ace prices that, not some other bet. Four taps, one at a time.
| What you're optimizing for | BET SMART judges the price against how often the bet wins over the long run. HIGHEST WIN % only asks which side cashes most often, whatever it costs. Bet Smart is the one that makes money. |
|---|---|
| Market | Spread, moneyline or total. Whatever your book is showing you. |
| Which side | The team, or over or under. |
| What line you're seeing | The number next to your side on your book's app: +3.5, -3, 47.5. Half points included. The chips are the board's number and a half point either way; type anything else under Other. |
| The juice / price | The number after the line: -110, -108, +150. Type the exact one. Ten cents changes the answer. |
On DraftKings, FanDuel or any regulated app, the line and the price sit together on the button you would tap to bet: “HOU +3.5 (-108)”. The first number is the line, the one in parentheses is the price.
The verdict
Hit PRICE IT and you get the call: BET or PASS. Under it, in order: how often we make it win against how often the price needs it to win; why, in points of margin; the fair price; and, on a pass, the number at which it becomes a bet.
THE CALL · HOU +3.5 at -108 · BET
We make it 56.2% to win. At -108 you only need to win 51.9% of the time to make money. If the model is right, that's about 4.3 extra wins per 100 bets like this.
We think Houston loses this by about 2, and the spread gives you 3.5 points of cushion. Losing small still cashes.
Our fair price on this exact bet is HOU +3.5 at -128. Anything better than that is value; anything worse and it's a pass.
| How often it wins | Out of 100 games like this one, how many times our ratings say this side comes through. Our honest read, before any price. |
|---|---|
| How often you need it to win | What the price demands. At -108 that is 51.9%. Below it you lose money over time however good the team looks. |
| The edge | The gap between those two, in wins per 100. A stand needs at least 3. Here it is 4.3, so it is a bet. At 1.5 it is a pass, and the box says so in the same voice. |
| It becomes a bet at… | On a pass: the line at today's price, or the price at today's line, where this side clears the bar. Still a pass until a book shows you that number. |
| The better buy | Inside a field goal we price the moneyline on the same side. If HOU +1 at -157 and HOU +160 to win are on the same board, the moneyline is the better buy, and the box names it. |
One unit
A unit is 1 percent of the money you have set aside for the season. On $1,000 that is $10. Ace never bets more than one unit on anything, and a pass is a full answer. Every BET says so under the call; it tells you how much a unit is, never to bet more.
Type your season money into the small field on THE RECORD and every unit on the site reads in your dollars: the call, the receipts, the pick log, You vs Ace. That number stays on your device and is never sent anywhere. Leave it empty and you get the $1,000 example instead.
The fair price
The fair price is the juice at which this exact bet, at this exact line, breaks even for you. It is always named with its line: “HOU +3.5 at -128”, never just “-128”. Better than the fair price is value; worse is a pass.
Sometimes the fair juice runs past -130, and no book posts a spread at that price; the book moves the number instead. So when you see “no book posts that juice; the number moves”, the sentence goes on to say where: “lay it out to KC -5.5, where our fair price is about -112.” That is the number you can actually shop for.
What moved the model
Each input is in points of final margin for your side. A plus hands your side points; a minus takes them away. Together they add up to our number before the price. Every angle we looked at lists every claim with its numbers: COUNTED moved our number, CONTEXT is what a sharp friend tells you anyway and moved nothing.
Our line vs the board
Our ratings make it HOU +2; the board has HOU +3.5. That is 1.5 points of line in your favor.
Points in your favor mean the board gives this side more than our number says it needs. Points against you mean the board asks more of this side than our number gives it. The edge above turns that gap into wins per 100 at the posted price.
Gun to my head
When your side is a pass, I'M ON TILT — JUST GIVE ME THE PICK prices the other side too. If the other side is a real stand, the box says so and hands you that side. If neither clears the bar, it names the least-bad side as exactly that, with the reason it is not a stand. It is never a bet dressed up as one.
Your decision
FOLLOWED MODEL, MY OWN PICK or NO BET. Freeze it and it cannot be rewritten after the result. Your own pick takes its side, line and price, and one reason. Once the game is final it is graded next to Ace's, on the record, under Your picks.
Chat with Ace
Under the wager form. Ace answers from the frozen case for this one game and nothing else. Ask him why he likes it, why he does not, or what would change his mind. How Ace got there under a reply lists the steps he took.
Anything you tell him about the world, an injury, a rumor, a screenshot, is a tip. He thanks you, it goes to the desk to verify, and nothing is re-priced on it. If it checks out, the stand changes with the reason and the sources written down. He does not do “if this is true, then…”. Not his chair.

Bankroll by day
The paper balance at the end of each day, as a line. Built from the settled stands and nothing else. Down money on well-priced bets is variance; down money on badly priced bets is a broken model. The bucket table under it tells you which one you are looking at.
The bucket table
One row per kind of bet, because they win at different rates and mean different things.
| Kind of bet | Won-lost-tied | How often it wins | What it needs | Settled so far | Units won |
|---|---|---|---|---|---|
| Sides | 7-4-1 | 63.6% | 52.4% | 12 settled · 3 still to come | +2.60u |
| Teaser legs | 5-2-0 | 71.4% | 75.6% | 7 settled | no stake |
Won-lost-tied counts settled bets; a tie is a push. How often it wins is wins out of decided bets. What it needs is how often the price has to win just to break even: above that line we are making money, below it we are not, and a row short of its number is marked. In the example the sides are above their number and the teaser legs are below theirs; both are shown, at the same volume. Legs are tracked for accuracy but carry no stake. Seven settled is a week, not a record; the sample is always printed next to the rate.
Why each row needs the number it needs
Every price is the same arithmetic. Take what you risk, divide by what comes back on a win (your risk plus the profit), and that is how often the bet has to win to come out even. The (i) beside each percentage does this sum for that row with the live prices.
| Sides and totals at −110 | Risk 110 to win 100. 110 ÷ 210 = 52.4%. Everything between 50% and 52.4% is the book's cut. |
|---|---|
| Teaser ticket at −120 | Risk 120 to win 100. 120 ÷ 220 = 54.5%. |
| Teaser leg | Both legs must land for the ticket to cash, so each leg needs the square root: 73.9% × 73.9% = 54.5%. |
| Moneyline legs | Each has its own price, averaged. A dog at +130 needs 100 ÷ 230 = 43.5%; a favorite at −150 needs 150 ÷ 250 = 60%. |
| Parlay ticket | Pays long because every leg must hit. At +1076 it needs 100 ÷ 1176 = 8.5% of tickets to cash. |
| Round robin | Several small parlays on one ticket, each at its own price; no single number, so the row shows a dash. |

The closing line
+3.5 → +2.5, +1.8 pts
We took Houston +3.5 on Wednesday. By kickoff the market had moved to +2.5: the world agreed with us and took a point away from everyone who came later. The +1.8 is our side's fair chance at the close minus at publication, with the book's cut stripped from both. Positive means the number moved our way.
Sharp bettors trust this more than win rate, because it shows up long before wins and losses do, and it does not depend on luck. A bettor who beats the closing line steadily is doing something right even in a losing week.
Ungraded
Waiting on a person lists games that are over but whose score cannot honestly grade the stand: a suspended game, a score feed that disagrees with itself. Nothing there is guessed, and nothing there counts in the numbers above until a person settles it. Bets on games that have not started are never in this list.
You vs Ace
Tap YOU VS ACE in the top bar. Your graded picks sit beside Ace's settled stands, on the same terms: won-lost-tied and units, one unit each at the price taken. Before your first pick goes final it tells you how many are waiting; after that the scoreboard runs all season. Your picks are listed underneath. A pass is a full answer, but it does not score.

Ace's crew: how each man thinks
Every number on the card was priced by one of the crew, and the card says which one. Each man has one method and sticks to it. None of these paragraphs says how good anyone is; the record does that, and it is graded the same way for all of them: did the number beat the closing line, and did it win.
Nicky, the consigliere. Nicky does not predict the game. He takes the sharpest number in the world, Pinnacle's, strips the juice out of it, and treats what is left as the truth about how often a bet wins. When Pinnacle has not posted, he takes the median of the sharpest books on the board, and failing that the whole board's, and the card says “consensus” when he did. Then he checks every US book against that truth. When a slower book still shows a number the sharp book has left behind, that gap is the whole bet. If no book is offering more than the truth, Nicky passes, and says what price would have turned him. Sides and totals.
Vito, the ratings man. Vito rates all 32 teams by who they beat and by how much, adjusted for the opponent; the ratings are rolled forward from the results by the research desk. His line is the difference between two ratings plus home field. He was the consigliere until September 2026. He kept his name and his record, and he is scored every night beside Nicky.
Paulie, the totals man. Paulie counts points both ways: what each offense scores, what each defense allows, and what that adds up to. His total is his own number, checked against the board's. Scored nightly beside Nicky on totals.
Lefty, the teaser man. Lefty only wants one thing: an underdog between +1.5 and +2.5 that six points carries through both 3 and 7. He builds the ticket from those legs and nothing else, prices it from the measured rate of that leg, and will not buy it at a price the rate cannot beat.
Carmine, the book's number. Carmine says what the market says and nothing more. He is the benchmark every other man is measured against: if you cannot beat Carmine, you have nothing.
Sonny, the kid. Sonny knows two practice games cold and refuses to price anything else. He minds the room when the real crew is out, which is to say on test boards, never on yours.
Frankie, the handicapper. Frankie builds his own number before he looks at the board. Last season's strength, regressed a third of the way to average, blended week by week with this season's point differential; the trend of the last five games against the season, and a read on each team as trending strong, trending weak, a bounce candidate, or mixed; a starting quarterback who will not play; rest; and a point and a half for home field. His edge is his number against the board's, turned into a cover probability with the thirteen-point rule. He leans on every game beside Nicky at no stake, and the record says which of them has earned the units.
Tips from the crew
Heard something — a quarterback who did not travel, a line that moved? Tell Ace: the game, what changed, what you heard, a screenshot if you have one, and a name for the credit or no name at all. Ace never moves on a rumor. A tip puts the game on watch and sends his informants to check now; only what they confirm can withdraw or revise a stand. When it does, the earliest tip on that game gets the credit, appended to the stand's record for good: “first reported by Tony R., 42 minutes before the wire.” Minutes before the wire is how long before Ace's own feed carried the fact your tip came in. The record lists every tip that moved Ace and each name's count for the season. A tip that never confirms stays between you and the desk; a signed-in tipster gets an email either way.

Responsible play
Bet what you can afford to lose. Everything on this site is priced for the long run; a single Sunday is noise, and a bet that was priced right can still lose. Ace runs on a paper bankroll; your money is real. You have to be 21 or older to bet in the U.S. If it stops being fun, call 1-800-GAMBLER. The number will still be there tomorrow.
