The Mushroom Roulette This device is a variation of the infamous so-called Russian Roulette. The four sections of the roulette-wheel are to be filled with the mushrooms depicted, or, if not available, with similar kinds. Most important is the choice of three edible and one poisonous species. In order to play, the two-part lid is closed, and the wheel is turned. Once it comes to a hault, the player takes out a mushroom sample through a triangular hole in the lid and eats it. The game may let us consider if really everything natural necessarily is healthy.
