Kristoon is a variation on the classic Blackjack/Pontoon theme where the objective is to get as close to but without exceeding a total of twenty-one. But Kristoon differs in that players can: ⁃ Only have a maximum of three cards ⁃ Offer a card to their opponents with the aim of bettering their hand ⁃ Swap an offered card to one in their own to better their hand Of course, an offered card runs the risk of being swapped for something else (and you will get that one back) or of being rejected by all your opponents so you get it back. Winners of the hand are awarded points (10 for Royal, 5 for Blackjack or 3 for nearest 21 otherwise. Matches are a set number of hands. Refreshingly easy to pick-up!
