Checkers is played by two opponents, on opposite sides of the game board. One player has the dark pieces; the other has the light pieces. Players alternate turns. A player may not move an opponent's piece. A move consists of moving a piece diagonally to an adjacent unoccupied square. If the adjacent square contains an opponent's piece, and the square immediately beyond it is vacant, the piece may be captured (and removed from the game) by jumping over it. Only the dark squares of the checkered board are used. A piece may move only diagonally into an unoccupied square. Capturing is mandatory in most official rules, although some rule variations make capturing optional when presented. In almost all variants, the player without pieces remaining, or who cannot move due to being blocked, loses the game. Checkers- Professional version has four modes to choose : 1. Computer is black. 2. Computer is red. 3. Computer v.s. Computer. 4. Player v.s. Player. There are three levels that you can choose : 1. Beginner 2. Intermediate 3. Expert

Diagonal Duel against a level 0-100 computer, with two players on the same device, or in ranked online games! Diagonal Two Squared is a game similar to Connect Four but essentially with the board rotated at 45 degrees. This allows for play on two "sides" from the start instead of the original game, on which you only play only along the bottom. The app allows for two players to play on the same device, to select a level from 0 to 100 computer to play against, or to play against random opponents.
