CrossZero
Real-time multiplayer tic-tac-toe on massive grids.
Think you know Tic-Tac-Toe? CrossZero scales the classic game into a high-stakes tactical battlefield. The match doesn't end at 3-in-a-row—you play the entire board (up to 10x10). Complete multi-triplet combos for points until the grid is full. Features real-time global multiplayer, 7 ELO ranks (Bronze to Grandmaster), private rooms with friends, and calibrated AI bots. Master the grid and outsmart the world!
Hi Product Hunt! 👋
I built CrossZero because I wanted to see what happens when you take a simple, solved game like Tic-Tac-Toe and introduce deep strategy, massive grids, and a competitive ELO ranking system.
Instead of the match ending after the first 3-in-a-row, you battle for points until the entire board is full. You have to plan multi-triplet combos and block your opponent dynamically. It runs smoothly on a real-time WebSocket backend for lightning-fast global matchmaking.
You can jump into public multiplayer to climb the ladder, generate a secure room code to play with friends, or train offline against AI bots ranging from Bronze to Grandmaster.
I'd love for you to try it out and let me know what you think of the scoring system and gameplay loop! I'll be here all day answering questions. ⚔️
