Echo · Memory Sequence
Each round a set of tiles flashes one after another. Watch the order, then reproduce it by tapping the tiles yourself. Get it right and the next sequence adds one more tile; get it wrong and the game ends. Your score is the longest sequence you nailed.
How to play Echo
Each round a set of tiles flashes one after another. Watch the order, then reproduce it by tapping the tiles yourself. Get it right and the next sequence adds one more tile; get it wrong and the game ends. Your score is the longest sequence you nailed.
What it measures
Echo is a visuospatial working-memory span task — a cousin of the digit-span and Corsi block tests used in cognitive psychology. It taxes your ability to hold an ordered set of items in mind for a few seconds and replay them.
Honest note: Training span games reliably makes you better at span games. Whether it boosts unrelated abilities is genuinely unsettled, so we won't promise it.
What's a good score?
The classic figure is seven plus or minus two; reaching level 9 or 10 is strong. The percentile we show is an estimate based on typical distributions, not a clinical norm.
FAQ
How is my score calculated?
It's the length of the longest sequence you repeated correctly before a mistake.
Any tips?
Group tiles into shapes or rhythms. Chunking beats brute memorisation.
