Choose a card from your hand and then try to complete the dice-roll challenge pictured on it. Depending on the challenge, you get between one and eight dice to roll. Some challenges are single-player, some allow you to challenge an opponent, and some include every player. Different challenges give you three rolls of the dice, or one, or an unlimited number to attempt your challenge. Various cards let you set dice aside and re-roll the remaining ones--while some cards dictate that you only get a single roll. If the dice don't go your way, you can cash in your chips for an extra roll, an extra turn, or perhaps a new card. The player that successfully completes their challenges--while wisely using their chips and re-rolls--is crowned the "Combo King."
