This test measures how well you hold your reaction speed while doing something else. When you multitask, your brain splits attention between tasks, which usually slows both of them down. The goal is to shrink that gap.
Test modes:
Comparison: First you take reaction trials alone to set a baseline. Then you take a second round of trials while playing brick breaker, and the two averages are compared. The trial count for each round is set separately.
Endurance: See how many reactions you can keep under the cutoff time while playing brick breaker. React too slowly or drop the ball and the run ends.
Reaction Time Only: Practice reactions with no second task. For a pure test with more settings, try the Reaction Time Test.
Controls:
Click or tap the right panel when it turns red
← → or A/D: move the paddle
Drag on the game area: move the paddle on touch screens
P: pause | ESC: end the test
Rules:
Clicking before the panel turns red is a false start and the trial restarts
In Comparison mode, dropping the ball resets your multitasking trial count to zero
In Endurance mode, reacting slower than the cutoff ends the run
Clearing all bricks spawns a fresh set automatically
Ending the test early is an abort — nothing is saved to your history
Tips:
Keep your eyes near the reaction panel and track the ball with peripheral vision
Park the paddle near the center and make small corrections
Start at slow ball speed and work upward
In Endurance mode, start at 500–600 ms and lower the cutoff as you improve
