Crosses-zeros

Crosses-zeros was one of those simple games you'd find during the Flash era, a time when a quick browser game could fill a few minutes. It took the familiar grid of tic-tac-toe and tried to add something new to the formula.

You play against the computer, taking turns placing your X or O on a three-by-three board. The twist is that you can set the computer's difficulty, which changes how often it makes the optimal move. Your main goal is to get three in a row before it does, but the game introduces mechanics like a timer or score tracking in some versions. The pacing is deliberate, each move requiring a bit of thought as you block the opponent and set up your own lines. It feels like a quiet, thoughtful puzzle more than a frantic competition.
