About
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.
