SuperSizeScale TicTacToe

Can You Reach Level 4?

It all starts with a regular game of Tic Tac Toe, but don’t be fooled—nothing stays simple for long! Win the round, and you’ll uncover the true scale of the challenge: you’re actually playing Super Tic Tac Toe.

Your AI opponent gets smarter and more challenging with every level. Do you have what it takes to conquer the final level?

Here’s a quick refresher on how 9x9 Super Tic Tac Toe works:

Super Tic Tac Toe combines traditional Tic Tac Toe with a larger strategy. The board consists of nine 3x3 grids arranged in a 3x3 formation, creating an overall 9x9 grid. Each turn, players place their mark in one of the smaller grids, but the twist is that the location of their move determines where their opponent must play next. For example, if you place your mark in the top-left corner of a sub-grid, your opponent must place their next move in the top-left sub-grid. The goal is to win three sub-grids in a row (horizontally, vertically, or diagonally), similar to how you’d win in traditional Tic Tac Toe.

The game was created in less than 24 hours — unfortunately, I had a major exam on Monday and couldn’t start earlier. The game might not be perfect, but it’s definitely still fun to play. There’s likely a bug somewhere in the AI code, which causes it to play a bit dumber than intended. I wrote around 300 lines of code for the AI, using a method where every possible move is analyzed to find the best strategy for the opponent (Minmax-Algorithm). I suspect there’s a small error (maybe a minus where there should be a plus) that’s affecting the AI’s performance. But hey, it is what it is. Enjoy the challenge!
