Primes drops two streams of balls onto the screen. One stream bears the number 7, the other carries 9. Your job is to sort each ball into the correct bowl: prime‑numbered balls go in the blue bowl, non‑prime balls land in the red bowl. The game blends casual play with a solid math challenge, turning every round into a quick number‑sorting puzzle. Master the swap mechanic, and you’ll feel the rush of precision every time a ball lands where it belongs.
The controls are stripped down to a single mouse gesture. You hold the mouse button, then release it to trigger a bowl swap. This single action decides whether the next ball lands in the blue or red container.
Start by focusing on the pattern of incoming numbers. The 7‑balls appear faster once you clear a few rounds, so keep an eye on the rhythm. When the red bowl holds a non‑prime ball, a quick swap can prevent a cascade of mistakes. As you progress, the game introduces mixed streams that require you to anticipate the next number before it drops. Speed up your swaps only when confidence is high; a mistimed release will send a ball to the wrong bowl and end the round. Aim to maintain a perfect chain of correct placements; each flawless sequence adds bonus points and unlocks a new visual theme.
