Test pattern recognition, memory, rhythm, color, pitch, and more.
Watch elements light up, then reproduce the exact order from memory.
Memorize which cells flash on a grid, then recall their positions.
Listen to a beat pattern and tap it back with precise timing.
Spot the transformation rule in a shape sequence and predict what comes next.
Find the one shape that's different among a group of similar items.
Complete a dot pattern's reflection across a symmetry axis.
Count dots that appear on screen for a fraction of a second.
Follow target dots as they move randomly, then identify them when they stop.
Spot what changed between two flickering versions of a scene.
Memorize a symbol codebook, then decode a sequence under time pressure.
Remember a color, then recreate it using a hue/saturation/lightness wheel.
Match a frequency from memory using a logarithmic pitch slider.
Numbered circles flash and vanish — tap them back in ascending order.
A path lights up through a constellation of dots — retrace it from memory.
Hear a melody, then reconstruct it on a pentatonic grid. Pure ear memory — pitch is hidden during playback.
Wait for the visual stimulus, then tap as fast as possible. Test your reaction time.
A hypnotic spirograph plays for a hidden duration. Press and hold to reproduce that span from your internal sense of time. Apex strips the playback — produce a target duration from a number alone.
Watch blocks drop into columns and stack. Grid clears. Rebuild the sequence from memory.
Decrypt a streaming terminal transmission. Recall the words via recognition grid, rapid-fire Y/N, and keyword extraction.
Mix primary color atoms to match a target color using color wheel knowledge. Chemistry flask meets subtractive paint mixing.
