Keep Prime Numbers
A browser-based racing game with a mathematical twist, this one swaps engines for arithmetic. Played in landscape on desktop, you clear a path by clicking or tapping blocks to drop composite numbers, leaving only primes for the number to pass through. It runs instantly in the browser with no install, pairing quick-fire number recognition with a simple, mouse-or-touch control scheme.
