Genie Gems is a theme on Petville. The player must first get a lamp to play, either as a gift from a friend or a purchase with PetCash. The lamps also replenish over time. The game has nine crates, which the player must choose until the game is over. There are coins, clean bombs, flowers, gems, and a snake, which ends the game. It is possible to not choose the snake, which grants an extra turn. There are 12 gems to collect, and once you have them all you can make a wish, which makes you choose a chest with a prize inside. The prizes are either coins, petcash, or clean bombs.
