TOT 3 is a completely original two-player, turn-based, strategy game that is played on an octagon-shaped board. It's completely different from but also in the style of board games like Othello (Reversi), Checkers, and Chess.
Although the strategy is very deep a person can learn to play without using a manual or following a tutorial. Just follow your intuition and make a few moves then watch what the computer does in response to your moves.
