Hi, I'm Ildefonso Zamorano, the founder and developer of TicToe.org. I build browser games and write about the history, strategy, and psychology behind them.
I've always loved web-based multiplayer games. There's something special about jumping into a game instantly in your browser and playing with someone on the other side of the world, with no installs, no accounts, just play. TicToe.org is my attempt at building exactly that.
It started as a small side project to see if I could make a real-time multiplayer game from scratch, and it grew from there. Most tic tac toe sites online are cluttered, slow, or push you towards creating an account before you can do anything. I wanted something that gets out of the way and just lets you play.
Games
- Tic Tac Toe: the classic, with vs Computer (Easy and Hard), local 2-player, and online multiplayer
- Ultimate Tic-Tac-Toe: nine boards in one, with vs AI and online multiplayer
- Terni Lapilli: the ancient Roman predecessor where pieces slide instead of stacking
- Rock Paper Scissors: vs computer or friends online, best of 1, 3, 5 or more
- Snake: the classic Nokia game, eat and grow without hitting yourself
- SameGame: a puzzle game about clearing coloured blocks for maximum points
- Achtung, die Kurve!: curve fever with online multiplayer for up to 6 players or vs bots
The blog
Alongside the games, I write about the history, strategy, and data behind them. That means deep dives into where tic tac toe came from, why the centre square has the lowest win rate despite being the strongest opening, and how rock paper scissors turns out to be far less random than it looks. There are over 20 articles so far. Browse all posts →
How it's built
The site runs on Node.js with Express for routing and WebSockets for real-time multiplayer. The game logic and UI are written in vanilla JavaScript with no frameworks. Blog posts are written in Markdown and rendered server-side.
The AI opponent in Tic Tac Toe uses the minimax algorithm, which explores every possible game position to guarantee optimal play. On Hard difficulty it is mathematically unbeatable.
