About

Goldfish Memory

Features
Read full description

GOLDFISH is a memory game with real bite that teaches memory techniques you can use in real life. Legend says a goldfish forgets everything in three seconds. Gil is out to prove the myth wrong — and so are you. Watch the pattern flash, then remember your way down through the Sunlight Zone, the Twilight Zone, the Midnight Zone, and into The Trench. WHY IT'S DIFFERENT • Adaptive difficulty that meets you at your edge — never too easy, never brutal. • A Memory Index that tracks Span, Speed, Focus and Flexibility, so you can workout your visuospatial working memory. • A global Top-100 leaderboard you climb with skill, not luck. • Daily Dive streaks that reward showing up. • Honest training — no brain-age nonsense, just real working-memory tasks. HOW TO PLAY Tap DIVE. Memorize the sequence of tiles as they flash, then tap them back before your oxygen runs out. Clear rounds to descend into deeper, harder water and survive modifiers like Riptide, Snapshot, Jellyfish and The Current. GOLDFISH PREMIUM Remove ads and support development with a Monthly or Annual subscription — more perks on the way. Slip up on a dive? Grab Continues and revive right where you left off. Prove the myth wrong. https://hivedevops.com/en/goldfishmemory/terms
