About game

Board game fans who crave a cosmic twist on classic logic will find Space Tic-Tac-Toe an addictive challenge. You battle a clever AI on a massive 10x10 grid while navigating the chaos of deep space. Placing your symbol starts a chain reaction that spawns a black hole on the board. These dark voids block specific squares for one turn, forcing you to think several steps ahead to secure a victory. Lining up five marks creates a win, but the shifting obstacles keep every match tense. Expect zero downtime as you constantly adapt your strategy to the unpredictable movement of these gravitational gaps. This modern spin on traditional крестики нолики makes every single session feel fresh and demanding. Jump into the action right here in your browser without any downloads or installations.
