|Player 1:||Player 2:|
Goal: have the most pieces of your color at the end of the game.
The two sides of each disk are a different color (one color for each player).
On your turn, lay a disk with your color facing up, in a position where disks of the opposing color are contained between the newly laid disk and a previously laid disk of your color. This can be horizontal, vertical, or diagonal.
All disks of the opposing color that are bounded between the newly laid piece of the current player and a previously laid piece of the current player are flipped so that the current player's color is face up. If this cannot be done, then you must pass.
See the Rules on Wikipedia for more detailed instructions on how to play.
