In the card game Shroom Boom players are hunting strange shrooms and everyone is trying to collect as many as they can before the season ends. The experimental shroom collectors evaluate useful shrooms by tasting them. However, tasting the wrong shrooms could lead you to hospital at the end of the game.
The game play is mostly memory driven but very challenging. During the game, players exchange the location of known shrooms with other players for their info on known shrooms while trying to memorize the current locations of the shrooms they are tracking. As soon as a player thinks he knows where to find a good set of shrooms, he starts to collect and taste them. Successful tasting makes the collector feel better (positive points), but tasting unknown shroom causes damage (negative points). If the player has less than zero points at the end of the game, he is considered to be sick.
