Number Memory

Features
Read full description

Can you remember 10 numbers in 5 seconds? Number Memory puts your working memory under real pressure — see the numbers, memorize them, then tap from smallest to largest without a single mistake. Your result isn't a generic "score." It's your Brain Age (not medical): a precise cognitive measurement based on the highest level you reached, your accuracy, and your reaction speed. Honest. Specific. Yours. No tutorials. No lives system. Just your memory versus itself. HOW IT WORKS • Numbers flash on screen in random positions • Memorize the full sequence before the timer bar runs out • Tap them in ascending order — purely from memory • Each correct round adds one more number to remember • One wrong tap ends the round and reveals your Brain Age BRAIN AGE SCORE • Algorithm combines level reached, tap accuracy, and response speed • Tracks your personal best — your real cognitive baseline • Share your score card directly from the result screen DESIGN & FEATURES • Distraction-free black & white interface — zero visual noise • Dark mode and Light mode — comfortable in any environment • Progressive difficulty: 3 numbers to 20+ as you improve • Grid layout adapts automatically as number count grows • Sound & haptic feedback on correct and incorrect taps HOW GOOD IS YOUR MEMORY?

Reaction Grid is a fast, minimal reflex game: a cell lights up on the grid - tap it before it's gone. Simple to learn, genuinely hard to master. HOW IT WORKS A random cell activates. Hit it fast for a higher rank and bonus points; miss or hesitate and your streak breaks. Every session tracks your score, accuracy, average and best reaction time, and longest streak. SINGLE PLAYER Sharpen your reflexes and climb the ranks - from Standard Hit all the way to Perfect Hit. A full performance report after every round shows exactly how sharp you were. TWO-PLAYER DUEL (Premium) Hand one phone to a friend and go head-to-head on the same screen - split grid, one timer, one winner. No second device needed. MADE TO FIT YOU - Two visual themes: warm "Reflex Lab" and cool "Synapse" - Three grid sizes (4x4, 8x8, 16x16) - Three difficulty levels and session lengths (1 / 3 / 5 min) - Full English and Turkish support PREMIUM Reaction Grid is free to play with ads between single-player games.
