So here are the rules for the game - the top row of dices are Rebecca's. You can't know what she has. The middle one is the dices that both of you see and the bottom one is the row with the player's dices. The goal of the game is to guess how many dices of a certain value are on the table. E.g. if the middle row shows 2,2,6,4,1 and your row shows 4,1,2,5,6 you know there are at least three dices showing 2's. But if you bet on it, the other player can raise the bet, saying there are at least four dices showing 2's (she might have a couple of 2's or if she has one and thinks that you have at least one). Alternatively, if she has two dices showing 6's she might bet that there are at least three dices showing 6's, because 6 is greater than 2. The rules of the game are that the bet can only go up (either for the quantity and/or the value of the dices) until one of the player calls the other 'liar'. Then both players show their dices and if the bet exceeds what's on the table, the one that made it losses, or if the bet is met by the dices on the table, the one that called him a liar is the looser.
