Start with the topics you know
English practice follows selected US Common Core arithmetic topics. Chinese and German select separate mental-math progressions; German primary practice offers Grades 1–4. This is arithmetic practice, not a complete curriculum. Each link opens the grade selector so you can confirm your choice before playing.
How much time do you get?
Grades 1–2 allow 15 seconds per question. Grade 3 allows 10 seconds. Grades 4–6 allow 10 seconds for regular questions and 20 seconds for challenge questions. Questions 5 and 10 are challenge questions.
Pick a practice mode
In Endless Challenge, answer ten questions to clear a level and continue to a new course. A wrong answer or timeout ends the run. For a single daily goal, try the Daily Challenge, which offers one free revive per attempt.
Use the game alongside learning
Try a sample question aloud before starting. For example, 7 × 8 can be worked out as 7 × 5 + 7 × 3 = 35 + 21 = 56. If the timer feels too fast, practice the method away from the timer first or choose an easier group. The game does not currently offer an untimed mode.
Best Endless levels are saved separately for each grade in this browser. Changing grades does not unlock a Daily Challenge you have already completed today.
