Each player has one Blue die that actually serves as the scorepad. It begins on ONE and the first player to get their Blue die to SIX wins the game.
Each player's turn begins with rolling the dice of the other colors. During the player's turn, they will use the abilities (while avoiding the downsides) of the dice. This will enable them to REFACE (manually change the facing on a die) or REROLL some of the dice in order to maximize the scoring opportunity on their turn.
At the end of their turn, they hopefully get to increase the number on their Blue die.
