2021, the end of Flash? Not so fast!

Did you know? Experimonkey is a contributor to Ruffle.rs, the world's first Flash games emulator. This means that, even after browsers disable Flash in December, you'll still be able to play all of your favorite Flash games here at Experimonkey.com! Experimonkey is always improving, so stay tuned for even more Flash games, mobile games, awesome experiments, cheesy jokes, cool facts, and more!

Oops... Looks like you're on mobile or flash is not enabled

We're trying to get some mobile games up and running, but unfortunately our flash games don't work on phone or tablet. How about some hilarious science jokes instead?

Ultimate Tic-Tac-Toe

  Full Screen

Choose from classic 3x3 tic-tac-toe (a.k.a. noughts and crosses), or go a little ultimate with 5x5 and even 7x7 tic-tac-toe. And when you're ready for a real challenge, play in multiplayer mode with both 2-person and online tic-tac-toe.

How to Play

Follow the in-game instructions.
