The life of a possum is not easy at all. Dangerous tigers, huge orcas and the occasional adorable panda.
Play your cards cautiously and be careful not to touch the number 21 or you will die forever.
There's only one chance, pretend you're dead and maybe you'll cheat death just this time.
Each turn play an opossum card or an animal card, Each card have a number (0-7), and each card played is added to the previously played card, if at any time you run out of cards to play or the sum of the cards is greater than 21 then you must discard a token of "playing the dead"
If someone cannot play a "playing the dead" token they lose the game and the player with the most tokens wins the game.
Special cards allow you to skip turns, have the rest of the players discard cards, or return the card counter to a lower number.
Or you can discard pairs of cards that add up to 14 to do effects like gain life, or recover cards from the discard
