Games Like KenKen
Love KenKen? Prime 59 brings the same math-meets-logic thrill with a prime number twist.
KenKen combines arithmetic with grid logic, and that’s exactly what makes Prime 59 feel like a natural next step for KenKen fans. Both games require you to think about number combinations that satisfy constraints, but Prime 59 focuses exclusively on addition with prime numbers. The target sum of 59 for every row and column creates a consistent constraint that’s easy to understand but endlessly challenging to solve. If you love the way KenKen makes math feel like a puzzle, you’ll love Prime 59.
