Nhẩm Nhanh

Nhẩm Nhanh turns everyday arithmetic into quick challenges with a lively pace and a playful sense of humor. • Sprint: complete 20 questions and work your way through five tiers. • 60-second challenge: keep your mental math streak going against the clock. • Tower: climb higher with three hearts. • Practice: choose from 83 topics, learn from examples, practice with guidance, and check what you remember. • Play with friends: compete 1v1 or create a group race, then compare results. • Records and leaderboards: track your best runs and in-game NQ score. NQ is a game score, not an IQ test. Play as a guest, or sign in to sync account progress and results across devices. Choose your number pad layout and adjust music and sound effects. On compatible iPads, write answers in solo games with Apple Pencil or use the number pad. Multiplayer and account sync require an internet connection.
