"Tic Tac Toe Cube" is an online puzzle that not every gamer can handle. Try it, maybe you will succeed. The difficulty is that you have to act not on one, but on 4 planes at once (according to the number of sides of the cube). The rest of the rules are the same as usual. The participants take turns. The winner is the one who first collects a line of four identical elements. The gamer can choose for free how to play: crosses or tac-toes. You also got the right to make the first move.
