嗨算!
An arithmetic drill that gets louder the better you do: every correct digit pumps up your “hype” score, and the effects and music escalate with it. From counting pictures for preschoolers to the four operations of Chinese primary grades 1–4.

About the game
Inspired by @grmchn4ai’s “ドパドリル” video. Every correct digit raises your hype score, which climbs through Chinese number units (万, 亿, 兆 … 不可思议) until it hits ∞. Keep going and bunting, light rays, cat friends and fireworks pile up, while the music speeds up and rises in pitch with every streak.
Eight modes: a preschool mode for counting pictures and adding or taking away within 10, then seven that follow the PEP (人教版) curriculum from Grade 1 to the first term of Grade 4: mental arithmetic within 20 and 100, times tables and division with remainders, then column arithmetic up to 3-digit × 2-digit multiplication and division by 2-digit numbers. Column problems are filled in one digit at a time, with carries, borrows and every long-division step shown.
Get 80% or more right on the first try to unlock EX: a 20-second fever round worth 10 extra points per problem.
The interface is in Simplified Chinese. It runs in mobile and desktop browsers, and number keys work too. Sound effects and music are synthesized in the browser.
