Number Gym — Brain Training

Train your mental math, memory, and logic with 20 short games. Each session takes a few minutes — long enough to feel the work, short enough to fit any pause.

THREE CATEGORIES, 20 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. • Logic — 6 games for reasoning, comparison, counting, and pattern recognition.

DAILY CHALLENGE A new set of 30 questions every day. The same for everyone, worldwide. See how you compare on the global leaderboard or among friends. Streaks reward consistent practice.

ADAPTIVE DIFFICULTY Each game has its own Elo rating from 0 to 100. As you improve, questions get harder. As you struggle, they soften. You always play near your edge — never bored, rarely frustrated.

COURSES WITH CERTIFICATES Structured lessons that take you from basics to advanced topics — mental multiplication, fast addition, percentage tricks. Pass the final exam, earn a certificate, share it.

FRIENDS AND ARENA Add friends, see their progress, challenge them in head-to-head matches. Weekly Arena ranks the most active players worldwide.
