Watch yourself learn the key
The same key, 90 seconds. Most people get faster from the first third to the last as lookups turn into memory.
Which pairs are locked in?
Dark = fast (learned), pink = slow (still looking it up). Play a round to fill it in.
Two ways to find a digit
Your eyes travel to the key on every answer. Speed depends on how fast you scan.
The pair is learned. Try Medium or Hard above, the key disappears partway through and only memory is left.
Code faster
Say the pair
Whisper "diamond four" as you press. Words help pairs stick.
Learn in chunks
Lock in 1–3 first, then 4–6, then 7–9.
Keep your hand on the pad
Rest fingers over the digits so pressing costs nothing.
Don’t chase errors
A slip costs one answer. Stopping to worry costs three.
Eye, key, hand
Coding is one of the few tests that uses seeing, remembering and moving at once. Pick a region.
A digit-symbol task was part of the US Army's picture-based test for recruits who couldn't read English. A version still sits in the Wechsler IQ tests today.
The Symbol Digit Modalities Test (symbol shown, digit given, like this game) runs for 90 seconds and is widely used to screen processing speed in clinics.
Matching symbols at speed
Use a key to pair digits with symbols as fast as you can. A core speed subtest of the Wechsler scales, and one of the most sensitive measures of processing speed.
Three places this skill turns up
Each one leans on a different part of what the game trains.
