A daily reaction time trial. Lowest clock wins.
About Grid Rush
Grid Rush is a daily Formula 1 reaction test. Twenty-five signals fire on a three by three grid and every millisecond you take is added to your clock. The rule board above the grid tells you what to do, and it changes: sometimes you tap the green cell, sometimes the rule reverses and the green cell is the one to leave alone. Everyone in the world gets the same run each day, and the day turns over at midnight UTC so two players comparing times are comparing the same puzzle.
How to play
- Three lights, then go. Nothing is timed until the lights go out.
- The board above the grid always tells you the current rule.
- Whatever time you take is added to your clock. The clock only goes up.
- One ranked run a day. Lowest total wins.
A new puzzle every day
Grid Rush resets at midnight UTC, not local midnight, so everyone plays the same puzzle on the same day wherever they are. Times are ranked lowest first, and a run counts once a day. It is free, there is nothing to install, and it works in any modern browser.
