How fast does your brain respond? These tests measure raw reaction time, processing speed, and visual tracking ability.
Reaction Time
Measure your basic processing speed, alertness, and neural conduction latency.
F1 Reaction
Formula 1 lights-out start sequence. React the instant all five red lights go dark.
Processing Speed
Rapid symbol search task to evaluate how fast you process visual information.
Object Tracking
Track highlighted balls as they move among distractors. Measures attentional splitting ability.
Target Shooter
Targets appear, grow, and vanish. Click them before they disappear. Pace increases over time.
How much can your brain hold? These tests evaluate short-term, working, verbal, and spatial memory capacity.
Working Memory
Digit span task testing your active short-term memory capacity and focus.
Sequence Memory
Spatial recall task: watch a pattern of tiles light up, then repeat it in order.
Verbal Memory
Words shown one at a time: is it new or have you seen it? Tests word recognition memory.
Chimp Test
Numbers flash on a grid then hide; click them in order. Inspired by primate memory research.
Pattern Memory
Memorize highlighted cells on a grid, then recreate the pattern from memory. Grid grows each level.
Can you stay focused and resist distractions? These tests measure sustained attention, impulse control, and cognitive flexibility.
Sustained Attention
Continuous performance task calculating your sensitivity index (d-prime).
Go / No-Go
Click for go shapes, hold back for no-go. Measures impulse control and response inhibition.
Stroop Test
Color words in mismatched ink: name the ink color, not the word. Tests cognitive interference.
Task Switching
Switch between categorization rules. Measures cognitive cost of mental shifting.
How precise and fast are your hands? These tests measure mouse aim speed, precision, and finger clicking rate.
Aim Trainer
Click 30 targets as quickly as possible. Evaluates spatial precision and motor latency.
Typing Speed
Find out how many words per minute (WPM) you type. Measures physical hand coordination.
Button Mashing
Click the button as many times as possible in 10 seconds. Measures physical clicking rates.
APM Test
How many precise actions can you fire in 60 seconds? Click highlighted grid targets as fast and accurately as possible — missed clicks cost you.
Keyboard Trainer
A key lights up — hit it instantly. Measures your raw keyboard reflex speed and accuracy under a 30-second pressure window.
WASD Dodge
How long can you survive? Dodge incoming enemies with WASD as the swarm gets faster — your survival time is your score.
How acute are your sensory organs and probability perception? These tests check color discrimination, internal time sense, and decision strategy under risk.
Color Perception
Find the slightly different color grid cell. Evaluates visual contrast and color acuity.
Blind Timer
Estimate time intervals without seeing a clock. Tests your brain's internal time perception.
Test Your Luck
Guess whether a double dice roll is less or high. Measures pure random probability and gut instinct.
Iowa Gambling
Test your risk tolerance and decision-making strategy under uncertainty and changing card deck yields.
