Neon XO: Tic Tac Toe

Neon XO is tic-tac-toe with a synthwave heart — the game you already know, wrapped in glowing lines, animated backdrops and a retro soundtrack. Draw your X or O on a board that hums with light and watch each mark ignite. Easy to pick up, quietly hard to put down. MODES - Play vs AI — a sharp single-player opponent that punishes every mistake. The best you can force is a draw. - Pass & Play — two players sharing one device, taking turns on the same board. - Online — remote matches against other players, coming soon.
