Powerdice is a light dice / card combination game for 2-4 players which can be played in 20 minutes. It is also a good learning aid in math for children. Players attempt to win tricks, but as your winning card does not count towards your points total, you need to win with as little margin as possible. Players are required to add 3 normal D6 dice for each player and a pencil and paper for keeping track of scores. There are just 2 sheets of cards, one page of rules plus the backs of the cards to print out. There is also a 1 page solitaire set of rules included in the package.
