About the game
Prime Hunt is a quick number game set on a bright lagoon floor. Five giant clams puff out bubbles with numbers on them, and an otter diver with a reed popper waits below. Pop the primes, the numbers that only split as 1 times themselves, before they float away. Pop a bubble that is not prime and you lose a heart.
But nothing is wasted. A popped composite cracks into its two factors, so 12 becomes 2 and 6, and those golden pieces are safe to pop: prime pieces score and count toward your goal, and bigger pieces crack again. Some bubbles rise already golden, and a gold 30 is worth three primes once you break it all the way down. Twenty-four levels grow from 2 to 12 up to numbers near 100, with faster bubbles and sneaky odd ones like 51 and 91.
