Also known as Doubting Dice. A game of bluff and counter-bluff usually played with a set of five poker dice, but as in Poker Dice a standard set may be used just as easily. Players are required to keep their dice concealed from other players so a throwing cup is recommended. Poker hands are used and rank as in Poker Dice.

Order of play is determined by each player throwing the five dice with the highest ranking Poker hand throwing first and the next highest second and so on. The first player rolls the dice, keeping them covered so the others can't see what's been thrown, and then announces their poker hand. The hand announced may in fact be the actual hand rolled or it can be a complete lie. If it's a lie it may be either a higher or lower ranking hand than the actual one on the concealed dice. The next player may either accept the hand called or challenge it.

If a challenge is made then the dice are revealed. If the challenger was right and the dice show a hand ranking lower than the hand declared by the last player then the challenged player puts a counter into the pot. If the challenger was wrong and the hand revealed is equal or higher to the one announced then the challenger puts a counter into the pot.

If the next player does not challenge the announced hand then the dice are passed to them without being revealed to any one else. He takes a look at them and may throw any of them again but must declare without lying how many are being rolled. He must then announce a hand ranking higher than the previous one.

Play passes to the subsequent players, each announcing a higher ranked hand, until a challenge is made. Once a challenge is made a player loses a counter and the challenger starts the next round. Players are out of the game when they lose their last counter. The last player left with a counter, wins the game.

Another version allows players three throws of the dice before they have to declare their hand. After each roll they may put aside any dice they wish to keep for their hand, rolling the remainder.
