In this speedy card game, players must rid their hands of all cards by quickly putting them down in the center pile. All cards are divided in two, showing a color and shape on each side. When matching, players must put down a card that matches either a color or shape on BOTH sides!

The games comes with a unique deck of 72 cards, each with a pair of colors and symbols. Speed is of the essence in recognizing colors and shapes and playing them at the correct instant.

It appears that this game is very similar to, but not the same as Double, also by Maureen Hiron.
