Sic Bo is a three-dice total game with many proposition bets. Small and Big are the common even-money markets. Specific totals, doubles and triples post higher prices and usually carry a higher house edge. Edge always comes from the posted payout versus the combinatorial chance on three dice.
Method: Small/Big expected value
Three fair dice have 216 equally likely outcomes (6³). Under the standard casino rule, Small covers totals 4–10 and Big covers 11–17 at 1:1, and every three-of-a-kind loses those bets. Each of Small and Big then wins on 105 combinations and loses on 111.
EV per unit = (105 − 111) / 216 = -0.02778 ≈ −2.78%. House edge ≈ 2.78%. Equivalent RTP ≈ 97.22%.
RTP Ledger uses this textbook combinatorial method. Confirm that your table still treats triples as losers on Small/Big before you rely on the figure.

Proposition bets
Specific triples, any triple, doubles and exact totals each need their own EV from (ways × payout − losing ways) / 216. RTP Ledger does not invent operator-specific proposition prices. Read the layout for the exact multiple before you compare edges.
Sic Bo RTP FAQ
What is Sic Bo Small/Big house edge?
On a standard three-dice table where Small (4–10) and Big (11–17) pay even money and all three-of-a-kind outcomes lose, each bet wins on 105 of 216 combinations. Expected value is (105 − 111) / 216 ≈ −2.78%, so house edge is about 2.78% (≈97.22% RTP).
Why are specific triple bets worse in Sic Bo?
A named triple has only one combination out of 216. Common posted prices still leave a much higher house edge than Small/Big—often near 30% on specific triples. Read the exact payout on the table layout before you bet.
Does live Sic Bo use the same edge as RNG Sic Bo?
Both formats follow the posted dice rules. Edge comes from the payout schedule, not from whether a dealer or RNG throws the dice. Confirm any rule changes on the help screen.
Side bets on Sic Bo can carry a much higher edge than Small/Big. Check the posted payout on every wager.
