Sudoku Dungeon is a fantasy tactical puzzle game where every battle is a Sudoku.

Each 9x9 grid is filled with enemies valued 1–9, and—just like a classic Sudoku—each number appears only once per row, column, and box. Your heroes can only defeat specific enemies based on unique rules. The Barbarian can only strike increasingly challenging foes; the Scout can clear fog when defeating an opponent; the Paladin smites enemies that do not conform to the rules of Sudoku; the Wizard (and his colleagues) creates fireballs that explode in Pentomino shapes; and more. With 25 characters, you'll craft ever-changing tactical solutions for each encounter.

Your role as Tactical Co-ordinator is simple in theory and devilishly tricky in practice:

Clear every enemy on the grid, use minimal energy and collect the loot.

Across 80 handcrafted puzzles, you'll confront five enemy factions, each escalating the challenge: Goblinoids, Undead, Beasts, Demons, and the enigmatic Elementals. Every biome ends in a boss battle that bends the rules in surprising ways. In each campaign mode puzzle, you are given a set group of heroes with limited energy. Many enemies have their own special rules which alter how you'll have to approach defeating them. Beat them all to help the Guild get to the bottom of the nefarious Enclave, vanquish whoever is behind their evil machinations and save the day!

Complete episodes to unlock heroes for Challenge Mode, where you can replay any puzzle you've beaten in the campaign now with your whole roster. Experiment with party synergy, and chase perfect-score solutions. Then see how you've done against other players in challenge mode score leaderboards.
