The active player first flips open a card that determines a category, then a letter card. S/he then has ten seconds to name a word that matches both cards. The next player flips open a new letter card and does the same, etc. A player who cannot find a word within the ten seconds has to keep the category card. The next player draws a new one. When someone draws a bomb card, all other players can pass a category card to him/her. When the exploding bomb card is drawn, the game ends after the current move and the player with least category cards is the winner. (User summary by HilkMAN)
