Tic tac toe against an opponent that never loses. In Impossible mode the computer searches every possible game with minimax, so the best you can do is a draw. Rigged mode is the comedy version: Rigby, a purple robot, plays perfectly and also cheats, calling dibs on your winning square, painting over your line or sneaking in a double move. It keeps a rap sheet of every cheat it gets caught pulling. There is also a 2 Player mode for two people on one phone or laptop. Scores are saved in your browser.
How to play: Tap or click a square to place your X. Get three in a row horizontally, vertically or diagonally. Switch between Impossible, Rigged and 2 Player with the tabs, and choose who moves first.

GameHub is a free directory of indie games you play in the browser, on the developer’s own site. We never host or re-upload games: every “Play” button sends you to the game’s official page. Links are checked daily, and developers can add their games for free.
