Neon Tic Tac Toe

Electric lines frame a neon board. Neon Tic Tac Toe swaps the usual marks for glowing stars and colored rings, then changes them again deeper into the run with shapes like triangles, squares, and hexagons. A computer opponent waits in the only available mode. Progress moves through three main tiers, and each one is split into three sub-sections before the next tier opens. Lives are limited. Run out, and the whole climb resets.

How to play?

Place symbols on the grid to line up three before the computer does. Block the rival mark when a row is forming. Wins move the run forward into the next match. Three cleared sub-sections unlock the second main tier. Later sets replace the ring and star with new geometric symbols, changing the look without changing the rule.
