Tic Tac Arduintoe Moves The Game To 4×4

We know you’re out there spending a lot more time with your loved ones, and appreciate that you may be running out of ways to keep everyone entertained. [Mukesh] dropped us a tip because he has the antidote to boredom — a new twist on that old chestnut, Tic Tac Toe.

Instead of the usual 3×3 configuration, [Mukesh] made the grid 4×4 so the game would be more engaging. Game play is otherwise the same — this Tic Tac Toe still results in a lot of draws, but they take longer and you can’t see them coming a mile away. What’s even more engaging is that you get to push clicky buttons that light up, and don’t have to draw a grid before every game.

Under the hood is an Arduino Uno that controls 16 push buttons and their corresponding RGB LEDs. Whoever goes first is blue, and player two gets pink. If you win, your color floods the board for a brief victory animation. If the game is a tie, the board turns red. We really like the printed two-piece buttons that house the LEDs and actuate the push buttons while keeping the two separate. Toe your way past the break to check out the build video.

Intrigued by the 4×4 version, but need a build that takes more time? Try building your TTT in TTL.

  1. Long time ago (mid ’90) I had tic-tac-toe running under DOS. It was using quite big matrix (50×50 or more – not sure), normal console characters (maybe was written in courses or similar) and you had to have 5 marks in a row not 3. I was using some simple “AI” that was blazing fast on my 486 with 4MB RAM resulting immediated response to any move. I noticed that it took a lot of effort to win.
