About
Memorize a pattern that flashes for just a moment, then tap it back in the same order — a simple memory game that's surprisingly hard to put down.
A quiet, immersive design built on "Minimal × Futuristic × Memory." For when you want to focus, alone, at night.
■ Two game modes
・CLASSIC: Memorize the order the cells light up, then tap.
・NUMBER: Memorize where the numbers flash, then tap them 1, 2, 3...
■ NORMAL / SPEED
・NORMAL: The classic mode that gets harder each round.
・SPEED: The display time keeps shrinking. Chase the 1-second limit.
■ Made for
・Refreshing your brain in spare moments
・Training memory and focus
・Playing quietly, with no ads or purchases
No ads. No in-app purchases. No account. No data collected.
All high scores are stored on your device.
Memorize the moment.
