A classic digit span test: memorize the digits as they appear, then type them back. Starts at 3 digits and grows by one each success — 2 misses ends the test. Most adults manage around 7.

The digit span task is one of the oldest measures of short-term and working memory: hold a sequence in mind, then reproduce it. Your span is the longest sequence you can recall reliably — for most adults that's about 7 digits, plus or minus 2.
This is an informal performance exercise, not a medical or diagnostic assessment. To make it a useful benchmark, retest under similar conditions and watch the trend.

Cognitive training exercises to improve focus
Every skill comes with a free test: get your baseline in under a minute, then retest weekly to track your progress. Scores are saved to your profile so you can watch them move as you train.
Calculate equations and make split-second pathing adjustments as the screen scrolls.
Real-world benefit: Faster decision-making under pressure and quicker reflexes while driving.
Hold numbers in short-term memory while physically navigating winding turns.
Real-world benefit: Better retention of names, phone numbers and daily to-do lists.
Trace a dynamic, shrinking path without drifting or lifting your finger.
Real-world benefit: Faster reactions, precise motor control and sustained attention.
Common questions
A classic working memory test: you're shown a sequence of digits one at a time and must repeat it back. The sequence grows by one digit each time you succeed, and your span is the longest sequence you recall correctly.
Most adults recall around 7 digits, give or take 2 — the famous 'magical number seven'. Spans of 5–9 are all typical.
Practice makes you noticeably better at the tasks you train and closely related ones — like holding numbers steady while using them. Games such as Number Stairs and Equation Forge train exactly that hold-and-manipulate loop.
