Prime Number Game
The only puzzle game built entirely around prime numbers.
Prime numbers are the building blocks of mathematics — numbers divisible only by 1 and themselves. Prime 59 turns these fascinating numbers into a puzzle game. You place primes (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31) into a 6×6 grid so every row and column sums to exactly 59. Why 59? Because 59 itself is prime, and it creates the perfect constraint for a challenging puzzle. Whether you’re a math lover who appreciates the elegance of primes or just looking for a fresh puzzle, Prime 59 is the definitive prime number game.
