These are called single number bets. The two number combination bets consist of placing a wager on any 2 dice combinations. If you wager on a 6,4 combination and the result of the dice roll was 4,7,6, you would win at 6-1 odds. You can only win on one instance of the two-number combination, so 6,4,4 would only pay out once. A three number total wager consists of combining the total shown on the resulting dice roll.
Different totals have different odds.
A result of 3 or 18 is always a loss. This wager pays out at 1-1 odds. All small or big wagers lose if the result of the dice is a triplet. Triplet Bets Triplets are when the resulting dice roll consists of all three dice containing the same digit. So if you wagered on three 6's and that was the dice result you would win at 150-1 odds.
