How it plays
Starts at three digits and grows by one each level. Time on screen per digit falls from 620ms toward 260ms over fourteen levels and then holds, so level 1 gives you nearly two seconds and later levels do not.
Scoring
No lives. One wrong digit ends the run and your score is the level you reached. Numbers never start with a zero, and an on-screen keypad submits itself as soon as the digits are complete.
Content
Endless and procedurally generated — no list to memorise, just the number itself.
What it tests
Digit-by-digit recall against a shrinking clock — working memory, measured one digit at a time.
