On each turn, the player rolls the four dice, then divides them into two pairs, adding up each pair. (For example, a player rolling a 1, 2, 3, and 6 could group them as 5 and 7, 4 and 8, or 3 and 9.) If the neutral markers are off the board, they are brought onto the board on the columns corresponding to these totals. If the neutral markers are already on the board in one or both of these columns, they are advanced one space upward. If the neutral markers are on the board, but only in columns that cannot be made with any pair of the current four dice, the turn is over and the player gains nothing. This is generally called 'going bust.'
