Finish 5 rounds to compute your official verified average reaction time.

💡 Keep your finger resting lightly on the mouse button or touchscreen to minimize travel latency.
💡 Do not try to guess the timing — false clicks will reset the round and penalize your score.
💡 Use a high refresh rate display (120Hz+) for the lowest visual input latency.
