MovingOthello vs OTHELLO KING

Every stone is a tactical trigger, and each capture fuels your next strike. ■Rule １．Each player places two stones in the four corners, and the remaining 32 stones are randomly distributed on non-edge squares. (Total: 40 stones) ２．Players take turns moving stones to positions where they can sandwich their opponent's stones with their own. ３．When a stone is moved, similar to regular Othello, any opponent's stones that are sandwiched between the player's own stones vertically, horizontally, or diagonally will be flipped to the player's color. ４．Each player moves stones 10 times, and the player with the most stones at the end wins. * There is a time limit of 30 seconds, and if a player fails to move a stone within the time limit, a stone will be moved randomly. * If there are no stones that can be moved, pass. ■Online Match ・You can compete online against people from all over the world. ・You can share a room pass and play against friends you know. ・In the case of friend matches, there is also a spectator mode.
