Sum Race Kids

Sum Race Kids (加法大赛车) is a cheerful two-player addition racing game built for kindergarteners aged 5 to 8. Two cartoon cars line up at the starting flag; the first child to tap the correct answer drives ahead. The race ends when somebody crosses the finish line — no timers, no penalties, just friendly side-by-side math practice.

Designed for early arithmetic
- Addition within 10 (and an optional within-20 mode for older kids)
- Big, finger-friendly answer buttons

- Each child picks their own car color and avatar emoji
- Built-in cheering sounds and haptic feedback so wins feel rewarding
