Diamant is a quick, fun game of push-your-luck. Players venture down mine shafts by turning up cards from a deck, sharing the gems they find on the way down. Before the next card is turned up, you have the chance to leave the mine and stash your finds, including any gems you get on the way out.
Why would you leave? Because the deck also contains hazards: scorpions, snakes, poison gases, explosions and rockfalls. When a duplicate hazard turns up (such as a second scorpion), anyone left in the shaft has to flee for safety and loses all the gems they got this turn. The trick is, the more players that leave, the bigger your share in the next card will be.
