Free Cognitive Tests for Gamers
Measure your reaction time, memory, and focus. Every score comes with a percentile from published research norms — free, no sign-up.
Reaction Time Test
Click when the screen turns green. 12 scored rounds measure your average simple visual reaction time in milliseconds — then a 6-round distractor block tests your impulse control separately.
Aim Trainer — Target Tracking Test
Keep your cursor on a moving target for 20 seconds. Measures hand-eye coordination as percent time-on-target.
Sequence Memory Test
Watch the squares flash, then repeat the sequence. Each success adds one step — how long a sequence can you hold?
N-Back Test — Free Working Memory Test Online
Watch cells light up on a 3×3 grid and press Match whenever the position repeats from exactly 2 steps back. 30 fixed-pace trials (28 scored, exactly 9 true matches) measure your working-memory balanced accuracy.
Stroop Test — Color Word Interference Test
Color words flash in sometimes-mismatched ink — respond to the INK color, not the word. 40 scored trials measure your Stroop effect: the interference cost in milliseconds.
Mental Rotation Test — Spatial Reasoning
See an original shape, then pick which of 4 options is that shape rotated — the rest are mirror images. 12 scored rounds of increasingly complex polygons, about one minute.
Multiple Object Tracking Test (MOT)
Memorize the red-flashing circles, track them as all 8 balls move for 5 seconds, then pick them out. 8 scored rounds, from 3 up to 5 targets.
Flanker Task Online — Selective Attention Test
Press the direction of the center arrow while ignoring the four flanking arrows — 5 practice trials, then 40 scored trials measure your flanker effect in milliseconds.
Go/No-Go Test — Impulse Control Test
Press for green circles, hold back for red rings — 45 rapid trials (5 practice + 40 scored: exactly 30 green, 10 red) build an urge to press that your score depends on resisting.
Task Switching Test — Cognitive Flexibility
Judge digits under two alternating rules — blue asks 'greater than 5?', orange asks 'is it even?' — with the rule switching every 2 trials. Your score is your switch cost in milliseconds.
Multitasking Test — Dual-Task Divided Attention Test
Track a bouncing dot and click it the moment it turns red — while classifying digits as odd or even. 16 dual-task rounds measure how much accuracy you keep when both tasks compete.
Rhythm Test — Beat Sync & Timing Accuracy
Tap the space bar or click in time with a 120 BPM metronome — 4 beats to listen, 8 to practice, 32 scored. Measures your average timing error in milliseconds.
