hextris takes the falling-block puzzle everyone already has muscle memory for and wraps it around a rotating hexagon, so instead of one floor to fill you are defending six edges at once. Blocks drop toward the center, you spin the hex to steer them, and matching colors clears them before the stack creeps outward and closes you in. It is the same satisfying loop of pattern and panic, viewed from a smarter angle.

The genius is how quickly it teaches itself. One look and you understand the goal; ten minutes and you are chasing a cleaner, faster clear. It is free, runs right in the browser with no download, and scales from idle distraction to genuine white-knuckle focus as the speed climbs. Keep it near our more puzzle games for when you want to think with your reflexes.
