About

Blanked

Features
Read full description

Blanked is a quick, warm, beautifully-designed brain game built for memory improvement, without the 30-minute clinical daily commitment. A scene flashes up for a few seconds, it disappears, and you answer questions about what you saw. Quick rounds. 2 minutes a day. That's all your brain needs. No clinical jargon. No scare tactics. No "your memory is at risk" marketing. Just a fun memory game that actually works. WHY BLANKED WORKS 2-minute daily sessions - play while the kettle boils 6 distinct memory game modes: Classic, Speed Recall, Snap Match, Sequence, Counting Blitz, Colour Chain 380+ levels across multiple worlds per mode Daily streak rewards that make memory training feel addictive, not clinical Weekly challenges with gem rewards Memory score analytics track your brain getting sharper week by week BRAIN GAMES THAT DON'T FEEL LIKE HOMEWORK Most brain training apps want 30 minutes of your day. Blanked wants 2 minutes. Short, consistent bursts of visual memory training strengthen recall, focus, and mental agility more than marathon sessions, that's what cognitive research consistently shows. A little every day adds up faster than you think. MADE FOR REAL LIFE Blanked is for people who do the NYT crossword with morning coffee, sudoku at lunch, or a quick word game before bed. Not clinical. Not childish. Just a well-designed brain workout that fits into your day - on the bus, in a queue, while the TV ads are on. SIX WAYS TO TRAIN YOUR MEMORY Classic — memorise a scene, answer questions about what you saw Speed Recall — remember where shapes were, tap to place them back Snap Match — two scenes flash, spot what changed before the timer Sequence — shapes flash one by one, tap them back in order Counting Blitz — shapes pop in and out, count each colour Colour Chain — memorise a colour grid, recall each position UPGRADE TO BLANKED+ Unlock the full experience: Unlimited lives — play as much as you want No ads, ever 100 gems every month Exclusive premium cosmetics for Blink (our mascot) Full Memory Score analytics + personal brain profile radar Monthly: £2.99 · Yearly: £19.99 with a 3-day free trial Subscriptions auto-renew at the price above unless cancelled at least 24 hours before the end of the current period.
