Situational history, only when it means something.
How a team, coach or quarterback has actually done in this week’s exact spot — home underdog, division rematch, current streak, last ten games. A record has to clear a real threshold to appear, and every card opens to the games behind it.

SIGNALS · EXAMPLE2 / 5
The live market, book by book.
Where one sportsbook’s price beats the rest, when a line has moved since Surf first saw it, and where books disagree on the favorite. Each one is rated by how much it matters to the same bet — never by a prediction of the result.

PREDICTION MARKETS · EXAMPLE3 / 5
Where the big money lands.
Prediction markets show their trades. When a large one fills on Polymarket, Surf flags it and puts it next to the sportsbook line, so you can see whether the books moved with it or ignored it. Every flag links to the venue’s own record of the fill.

GOOD QUESTIONS
Before you
dive in.
Is Surf a sportsbook?
No. Surf is an independent analytics tool. You explore information here; Surf does not accept stakes, hold betting funds or place bets.
Do I need to be an experienced bettor?
No. Start with the free Games board to compare prices for a matchup. The field guide explains signals, odds and what the numbers can—and cannot—tell you.
Does a signal mean I should bet?
No. A signal highlights something in the observed data worth examining. Prices can change, historical patterns can be misleading, and no signal guarantees a winning result.
What does Surf Pro add?
Surf Pro is $9.99 per month and unlocks Signals and Trends for every matchup. Without it you still get the market board, game briefs, and one featured matchup of each every week. Check your account for availability.
