Ataxx is a free board game available on Android developed by M. Brodski Software. The game is played on a square board consisting of 7x7 fields, with two players playing against each other. The game starts with each player having two pieces. The goal is to have the highest number of pieces on the board at the end of the game. Players take turns moving one of their pieces one or two spaces vertically, horizontally, or diagonally to a target field. When a piece is moved one space, it is maintained, but when it is moved two spaces, only the new piece remains, and the original piece disappears. All adjacent pieces around the target field change their color. The game ends when all fields on the board are filled, or a player has no more moves available. The game has three levels of difficulty: easy, normal, and hard, which can be controlled using the traffic light. Overall, Ataxx is an entertaining and challenging board game that is easy to learn and play.
