Mantis Game
With the simplicity of UNO and depth of Gin Rummy, Mantis is designed for both kids and adults. But adults should be warned that kids will often beat them at this game!
There are only two rules: Steal or Score. You collect matching sets of cards by stealing from your opponents. You feel good about things, then not so good about things as opponents steal your cards back. Repeat this emotional rollercoaster until somebody wins the game.
