Lockpicker

How well does someone remember a pattern under pressure? A key, a screw, a dog. Six symbols flash in a certain order. Remember them and reproduce them. The sequence gets longer, and longer. In three minutes Lockpicker measures the size of someone's working memory.

3 Reasons we love this assessment

01
Done in a few minutes
No long test environment, no proctor, no test anxiety. Open the app, play the mini-game, done. Faster than filling in an application form.
02
Just as accurate, more fun
Scientific research shows: well-designed game-based assessments measure as accurately as classic psychological tests but with less stress and more engagement.
03
Everyone gets the same shot
No advantage or disadvantage for your name, your background, or who you know. No gut feeling that midway whispers 'this one doesn't fit'.
Technical Details

Information

3 minutes, adaptive

The test adapts to the candidate's pace: get it right and the sequence gets longer; get it wrong and it gets shorter.

Universal symbols

Animals and objects. No language, no culture required. Equally fair for everyone.

Measures what you can't train

Working memory is one of the most stable cognitive traits. Lockpicker measures capacity itself, not a trained trick.

Scientific foundation

This test is based on classic digit span tests in use since 1957.
