The daily memory challenge
Five rounds. Tiles flash, you remember where they were. Everyone in the world gets the same puzzle today. Share your grid, keep your streak.

How it works
- One puzzle a day. The patterns are generated from today’s date, so every player faces the same five rounds. Tomorrow at midnight (your local time), a new one unlocks.
- Five rounds, rising difficulty. Round one flashes 3 tiles; round five flashes 7. Three lives cover the whole run.
- Share your grid. Purple is a hit, red is a wrong click, white is a miss. Compare with friends playing the same puzzle.
- Streaks are the point. Memory training compounds daily. The streak makes showing up visible. (Curious why streaks work on your brain? We wrote about the neuroscience of streaks.)
What today’s puzzle is actually training
Each round is a visuospatial working-memory task: encode a set of positions in about a second, hold them across the blank, and reproduce them. That is the same task family as the Corsi block-tapping paradigm that cognitive psychology has used since the 1970s, and the same skill measured by our full visual memory test. The capacity you are bumping against in rounds four and five (six or seven positions) is the well-documented limit of working memory: most adults hold 4 to 7 spatial items at once.
One daily puzzle keeps the skill warm. If you want to actually push the ceiling, that takes repeated, varied practice at the edge of your ability, which is what the six game modes in the app are designed around: two minutes a day, at your level, with a properly tracked streak.

How does the daily challenge work?
Every day there is one puzzle, and it is the same for every player in the world. Five rounds on a 5x5 grid: tiles flash for just over a second, then you click the ones you saw. Each round adds one more tile. You have three lives across the whole run and one attempt per day. A new challenge unlocks at midnight, your local time.
Is it really the same puzzle for everyone?
Yes. The tile patterns are generated from the date, so everyone playing on the same calendar day gets identical rounds. That is what makes shared results comparable, like Wordle.
What does the share grid mean?
Each row is one round. A purple square is a tile you found, a red square is a wrong click, and a white square is a tile you missed. Five clean purple rows is a perfect day.
How do streaks work?
Play the challenge on consecutive days and your streak counts up. Miss a day and it resets. The web streak is stored in your browser, so it will not follow you across devices; the Blanked app tracks your streak properly on your account.
What memory skill does this train?
Visuospatial working memory: holding positions in mind for a few seconds and reproducing them. It is the same task family as the Corsi block-tapping paradigm used in cognitive psychology research. One puzzle a day is a nudge, not a training programme; consistent daily practice is where measurable improvement comes from.
Do you store my results?
Only in your own browser (for the streak counter). Nothing about your play is sent to our servers. Standard site analytics may record the page visit, but not your score.
