The Slip Builder turns our live +EV board into a ready-to-bet slip. Tick the sportsbooks you hold and the sports and bet types you want — player props, game lines, and optionally exchange markets from Kalshi, Polymarket, and Novig — set a bankroll, and it assembles the bets our system rates highest right now: the best price for every market across your books, ranked and sized with quarter-Kelly stakes, capped at 25% of your bankroll per day and 5% per bet. Prices are whatever is on the board the moment you build, and deep links at DraftKings, FanDuel, BetMGM, Caesars, and BetRivers open each bet pre-filled in your slip. All for free.
This is not a separate picks product. It is the exact rule our public EV track record follows, pointed at today's games with your settings — the same code that sizes the tracker's graded history builds your slip. The tracker locks its picks from whatever is on the board at each half-hour; a slip you build is that same decision, made at the moment you build it.
Every +EV market on the board for the games you ticked is considered at the best price among your books. Both sides of the same market are never both taken, and only one line per player prop makes the slip. Bets are then ranked by recommended stake (quarter-Kelly) or EV%, staked at Kelly % × bankroll, capped per bet and by the daily budget, and the slip stops when the budget is spent — the same daily rule our track record follows.
Yes — the identical ranking and sizing code. The profit tracker grades what this rule selected on past days; the Slip Builder runs the same rule on today's board with your settings. The defaults here match the tracker's default view, so the tracker is, quite literally, this tool's public, graded history.
Those are the ranges where our graded results have been most reliable: below 3% EV the board has run near break-even at flat stakes, and on price the edge runs from short favorites through small plus-money lines around +101 to +124 and stops there — from +125 on, flagged bets have run flat, the well-documented favorite–longshot bias. Every setting is adjustable if you want a wider board.
Tick “Include exchange markets” to add game markets from Kalshi, Polymarket, and Novig alongside your sportsbooks. Exchange bets don't have bet-slip links yet, so you place those on the exchange yourself.
Prices move constantly, and nothing is saved between builds — every build reads the live board fresh. If you untick “Only today's games,” football games posted days ahead will appear in each build until they're played. Your settings are remembered in your browser; the slip itself is not.
No. The Slip Builder is information — a systematic view of where current prices sit relative to our probability estimates. Odds move, so always check the price at the book before you bet, and what you can legally bet depends on where you are. Past results are not a promise of future ones; bet responsibly.
