Logic Puzzle Games
A logic puzzle game that challenges your deduction skills with prime numbers.
The best logic puzzle games give you a set of constraints and let you reason your way to the solution. Prime 59 does exactly that: every row must sum to 59, every column must sum to 59, and you can only use prime numbers. From these simple rules emerges a rich chain of logical deductions — if this row needs 59 and already has 23 and 17, the remaining cells must sum to 19, and there are only certain prime combinations that work. Each deduction leads to the next, creating the “aha!” moments that logic puzzle fans live for.
