Phase 10 Dice

You win the game by being first to get through the 10 Phases with the highest overall score. Six of the dice contain all the high numbers. Each of these is numbered 5 through 10 in the four colours. The other four dice contain the low numbers and the Wild (W) faces. Each of these dice is numbered 1, 2, 3, 4, W, W in the four colours. In a turn, the player starts by rolling all ten dice. The player may then set aside any dice he wishes to keep. He makes a second roll with the remaining dice. He may set aside some of these dice, adding them to those already set aside; he may also take back some of the dice previously set aside. Then he makes a third and final roll, scores and ends his turn. Each phase specifies which dice are needed (sets, runs, flushes), so this is sort of sequential Yahtzee.
