Kana Slot Car 3D is a free browser racing game where the tracks are real Japanese Hiragana and Katakana characters, rendered in full 3D. Every track follows the actual stroke order of a character — and where strokes cross, the track becomes a real overpass you drive over and under, so the structure of each character is something you physically experience.
Use W or the up arrow to accelerate, and S or the down arrow to brake. Your slot car follows a groove cut into the track — but carry too much speed into a tight curve and you'll fly off in a tumble! Red-and-white kerbs mark the corners that demand braking. Switch between a low chase camera and a slowly orbiting overview with C.
Race the Nihon Grand Prix across every character connected into one giant circuit, pick any single character for a 5-lap race, or take on a whole family in Grand Prix mode. Each character has gold, silver and bronze target times; beat them to earn medals and XP, and race the translucent ghost of your own personal best.
Before each race, an animated preview draws the character's stroke order — then you drive exactly those strokes, in order, with numbered gates marking where each stroke begins. The character itself is painted beneath its track. At night the slot grooves glow — try dark mode.
