Fathom Tesserae

Fathom Tesserae is a cyberpunk 8-bit strategy take on classic Tic-Tac-Toe.
You play as X against an abyssal AI (O) on a neon tactical grid inspired by retro console-era pixel art.

In each round, place your mark on open tiles and create a line of three before the AI does.
The opponent uses tactical decision-making, so positioning and threat control matter: center control, corner pressure, and fork prevention can decide the game.
