Remove all the blocks to make the composite number going out but keep the prime number. Click or tap the unused block to drop the composite numbers.
Throttle up in Keep Prime Numbers and see how well you handle the curves. Your aim is to shave seconds off your lap times by finding the racing line on every corner. Controls: WASD to drive, mouse clicks for menu choices. The car responds to how long you hold each key, so feather inputs into turns. Tips to get better: Look at what the top scores on leaderboards have in common — it's usually a specific strategy. Power-ups are more valuable when you save them for the moment you're about to lose. Every game has a rhythm. Find it early, commit to it, and your scores will climb fast. If you're drawn to games with a keep, prime, numbers flavor, Keep Prime Numbers hits that spot cleanly. Keep Prime Numbers is short-session friendly but gets surprisingly deep if you stick with it.
