Love Sudoku? Try Prime 59 — a fresh number puzzle with prime numbers and competitive multiplayer.
If you enjoy Sudoku, you already know the thrill of filling a grid with numbers that satisfy every constraint. Prime 59 takes that same logic-puzzle satisfaction and adds a mathematical twist: instead of placing digits 1–9 without repeats, you place prime numbers so every row and column sums to exactly 59. It’s familiar enough to pick up instantly, but the prime-number mechanic creates entirely new solving strategies. Plus, unlike Sudoku, Prime 59 features real-time multiplayer battles, daily challenges, global leaderboards, and five difficulty levels from Easy to Master. If you’re looking for the next puzzle to scratch that Sudoku itch, Prime 59 is it.
