The slip

Adding legs

The + on any row adds it to the slip. On a wide screen the slip is the rail on the right; on a phone it is a drawer. The same slip either way — it does not fork.

The combined figure, and what it assumes

With more than one leg the slip shows a combined probability captioned combined · assumes independence. That caption is the important half. The combined number is the legs multiplied together, which is only true if the legs are unrelated — so the assumption is printed beside the number, always, on every slip surface.

When it is not true, the slip says so: two legs in the same game are correlated, and the app shows “Two legs are in the same game — correlated, so the combined number is optimistic.” Optimistic means the real chance is lower than the figure above it.

A single leg is a straight bet: there is nothing to combine and no independence to assume, so the caption says 1 leg · straight instead.

Fair odds beside it is that probability expressed as American odds with no margin added — what a book charging nothing would post. It is a translation of our number, not a price you can get.

Logging it, and the hand-off

Logging a slip records it in your bet log — what you played, where, at what price. Your ledger is yours alone; nothing about it is published, and it is included in the account export you can download at any time.

Where a sportsbook link appears, it hands you off and stops there. We do not take wagers. Odds shown are the last snapshot we read and may have moved. TrueProps is a sports-analytics product, not a sportsbook — we accept no wagers and hold no gambling funds. 21+.

If betting has stopped being fun, that is worth reading about on responsible gambling.
