Tic Tac Toe: Neon Duel

Tic Tac Toe: Neon Duel is the game you already know, rebuilt as a glowing arcade duel.

Amber X. Electric cyan O. Every mark burns itself onto the board, the winning line fires like a laser, and the screen flashes in the winner's colour. It is the classic game of three-in-a-row, with the atmosphere of a late-night arcade.

PLAY YOUR WAY
• Two players on one device — pass and play, no internet needed
• Play against the computer and choose whether you are X or O
• Separate scoreboards for two-player and vs-computer, so your records never mix

FOUR REAL DIFFICULTY LEVELS
• Easy — relaxed, made to be beaten
• Medium — a fair fight
• Hard — you will have to concentrate
• Impossible — perfect play. It cannot be beaten, only drawn.

The computer uses a full minimax search, so "Impossible" really is impossible. The easier levels are not just a slower version of the same opponent — they make genuine mistakes, so every level feels different.

MADE TO FEEL GOOD
• Neon marks that draw themselves in
• A laser that fires down the winning line
• Particle bursts and a screen flash when you win
• Sound effects you can switch off any time
• Fits every screen size, from small phones to tablets

NO NONSENSE
• No sign-up, no account, no login
• Works completely offline
• Small download
• No personal data collected

Whether you are killing five minutes or trying to finally draw against a perfect opponent, Tic Tac Toe: Neon Duel is the classic game, done properly.
