Shotgun Jousting

Two gangs of bikers meet in the desert and after drinking themselves silly decide that jousting on their motorbikes, using shotguns rather than lances, is a good idea. A two player push your luck game. Each player has 11 cards, and each selects and plays one card from their hand simultaneously until one or both players plays the "BLAM" card, which ends the round. The player playing the "BLAM" card scores for the cards they have already played this round. The game is played over four rounds.
