Similar to Othello, Hexxagon is a classic puzzle/strategy game based on the arcade game Ataxx, where the goal is to take over the board with your stones. Your opponent's stones transform into your stones when you move yours into a space next to theirs, and once the grid is filled, the player with the most stones wins.

During every move, the player can move whether he wants to duplicate one of his stones to an empty adjacent field (originating stone remains), or whether he want to jump with the stone to an empty field which is 2 spaces away. Once your opponent cannot move any more, all empty fields are automatically populated with your stones. This fills up the board and brings the game to its end.
