3×3 GRID · 15 ROUNDS
Spot the lit tile and select its position as fast as you can.
Complete 15 rounds to measure your reaction time and accuracy.
READY?
Press 1–9 or tap the tile that lights up.
Keyboard: keys 1–9 match the grid · Touch or mouse: select any tile
HOW TO PLAY
Start the game and focus on the center of the 3×3 grid.
When one tile lights up, press its number or select it directly.
Standard mode ends after 15 rounds. Endless mode gets faster and ends on the first miss.
VISUAL POSITION REACTION
The visual reaction grid combines detection, spatial attention, and choice speed. You must notice which location changed, map it to one of nine responses, and act quickly.
Standard mode records the response time of correct selections and accuracy across all 15 rounds. A wrong tile still advances the test, so both speed and control matter.
READ YOUR RESULT
Average reaction time uses correct rounds only. Accuracy is the share of all rounds answered correctly, including early inputs and wrong tiles.
Input delay varies between keyboards, mice, and touchscreens. For a useful personal benchmark, replay on the same device with the same input method.
QUESTIONS
Reaction time runs from the instant a tile lights up until you respond. The displayed average uses correct responses, while accuracy is correct rounds divided by every completed round.
Keys 1, 2, and 3 match the top row; 4, 5, and 6 match the middle row; and 7, 8, and 9 match the bottom row. The number is also shown on every tile.
Every correct tile grows your streak and shortens the response deadline. Selecting the wrong tile, pressing early, or running out of time ends the run.
Yes. The grid is designed for touch, mouse, and keyboard play. Use the same device when comparing results because input latency can change your measured time.
