This game is based on a paper game that I can't remember the name of, but it was fun. A grid of dots is drawn, size of the grid usually determines the length of the game. Each player takes a turn connecting two dots with a horizontal or vertical line, as time passes channels will develop. Point of the game is to connect the dots into blocks, so when a block has three closed sides and the player closes that block, it is marked as his and he takes another turn. This continues until all blocks have been claimed.
