S.P.E.R.M.S. is a card game in which players play squads of commando sperm trying to battle and race each other to overcome Egg Defenses and be the first to reach the egg. Players are dealt Position cards which indicate their respective progress towards the egg. On each player's turn, he must attack the player ahead of him, using a modified rock/paper/scissors combat system, that can result in players drawing cards, killing enemy soldiers, or switching positions with the other player. Players in first place instead "attack" an Egg Defenses deck, which functions in a push-your-luck fashion to either reward or punish the leader, and will eventually give up the winning egg card (several decoys must be uncovered first). The game is full of puns, innuendoes, and adult humour. 128 cards. 4 pages of rules. 43 illustrations in full colour.
