Number Gym: Brain Training

Train mental math, memory, and logic in five focused minutes a day. 21 short games that meet you at your level and grow as you do. No ads, no tracking, no streaks shaming you — just a calm daily practice for a sharper mind. THREE CATEGORIES, 21 GAMES • Arithmetic — 9 games for mental calculation: addition, multiplication, equations, missing numbers, fractions, percentages. • Memory & attention — 5 games to recall numbers, sequences, positions, and visual patterns — and to catch numbers at the edge of your vision. • Logic — 7 games for reasoning, pattern recognition, logic circuits, and rotating shapes in your head. ADAPTIVE DIFFICULTY Every game tunes itself to you. Each has its own rating from 0 to 100 — as you improve, questions get harder; when you struggle, they soften. You always play near your edge: never bored, rarely frustrated. DAILY CHALLENGE A new set of 30 questions every day, the same for everyone worldwide. Compare on the global leaderboard or among friends, and build a streak for consistent practice. CALM BY DESIGN No ads. No tracking across other apps. No shaming streaks, no flashing rewards, no addictive loops. Number Gym respects your attention — it's built to be put down, not to keep you hooked.
