GT99 Sic Bo: Dice Rules, Bets and Probability

The dice and the layout

Three dice produce totals between three and eighteen. The betting layout shows these totals, single numbers, pairs of numbers, and the categories Small and Big. The extreme totals of three and eighteen can only occur in one way each (all ones or all sixes), so they pay the most. The middle totals of ten and eleven occur far more often, so they pay the least.

That is the entire logic of payout tables: rarity sets reward. If you see a bet with a high payout, it is because few of the 216 equally likely dice combinations satisfy it.

Bet categories

The common ones are listed here.

Why Small and Big have an edge

Without a rule, Small and Big would be close to even. The edge appears because a triple, which would otherwise make a Small or Big win, counts as a loss for both. That removes six of 216 outcomes from each side. You can verify this by listing the outcomes, which is a good exercise for anyone who likes checking arithmetic.

Choosing bets

Single-number and Small/Big bets give the lowest edge in the game. Specific totals and triples carry a higher edge in exchange for larger payouts. If you combine many bets in a round, your stake per round rises quickly, so total the amount before confirming.

• Count the total of all bets placed in a round.
• Compare it with one tenth of your session budget.
• Remove the highest-edge bets first if it is too large.

Checking the round result

After the dice settle, the screen highlights winning bets and shows the total. If your balance does not match what you expected, open the round history and compare each bet with the dice shown. Most disputes come from a missed rule, such as the triple clause on Small and Big, rather than from any fault in the game.
