Frequently asked questions

Who should I bet in Southern Illinois vs. Illinois?

We don't issue picks. This page shows where the tickets and the dollars are landing so you can weigh that against your own read of the matchup.

Where does this data come from and how often does it update?

We aggregate publicly reported sportsbook handle on a sub-hourly cadence and store every snapshot, so a game's splits can be read as a series rather than a single reading. This page shows the most recent snapshot before kickoff.

How big does a bet/money gap have to be to matter?

On college spreads the median gap is about 11 points and roughly a quarter of games clear 24, so the bar sits higher here than in a professional league. On totals the same number means considerably more — a 20-point totals gap is about three times rarer than the same gap on a spread.

Does fading the public work in college football?

Not as a blanket rule, and we don't present it as one. Heavy public sides are priced knowing the public is coming, so the lean is partly in the number already. What we track is where the ticket count and the dollars disagree, which is a narrower and more specific thing than fading whoever is popular.

Where can I bet Southern Illinois vs. Illinois?

Any licensed sportsbook in your state offers college football markets. We don't recommend specific books — please read our responsible gambling resources before wagering.
