What you get

Tonight’s homework, done before the game.

A short list with the reasoning on every line, an explicit pass on the games with nothing in them, and every number written down before it starts.

  • Every NFL player, priced before kickoffHis touchdown chance and his yardage and catch lines: Certy’s % beside DraftKings’ price, with the time we saw it.
  • Tonight’s NBA gamesEvery game on the night with DraftKings’ line, free for everyone.
  • Parlays priced togetherBuild the slip in the app and see the combined chance with same-game legs adjusted, not a naive multiply.
  • Ask, the chat that read the boardAsk about a player, a price or a word on the screen, and it answers from our numbers and the graded record.
  • A record that’s never editedEvery call is timestamped before the game and graded in public. Misses stay up next to the hits.
Running right now

The model is already working.

The free plays below come straight off today’s board: each one is written down before the game starts and graded from the official final.

Loading today’s board…
Certy’s % is an estimate, not a promise. Each play is written down before the game starts and graded from the official final, hit or miss. How good the number is, and where it falls short, is under How it works.

How it works

Four steps, and none of them are a black box.

1

We price the board

Before each game the model prices the board from its own numbers, player by player, with no sportsbook margin baked in. DraftKings’ price sits beside it.

2

You see the reasoning

Every play carries what drives it, in plain English, with the arithmetic left in.

3

It tells you when there’s nothing

A game with nothing in it gets an explicit pass, not a manufactured play.

4

We keep the receipt

Build the slip, place it at your book, and the call is graded in public after the game. Wins and misses both, never edited.

How good is the number? Tested on 1,548 past MLB games, our side model called 54.5% of games right; the last price a sportsbook posts before a game did better (57–58%). That is why every play shows DraftKings’ price beside ours, and why the record keeps every miss.

Per-day figures divide the plan price by 365. Baseball ends in late October and football in February, so there are quiet stretches where the board is thin; the yearly plan exists to carry you across them, not to claim 365 days of picks.

Why trust it

Most picks accounts delete their losses. We don’t.

Every call is written down before the game starts and graded after it ends. You can see the whole history, not a highlight reel of good weeks.
