Probably-Sudoku

Probably Sudoku is a roguelike number puzzle built around Sudoku rules, powerful combos and Books with personality.

Choose from 12 Books, each with its own ability and questionable encouragement. Place numbers using Sudoku rules, build scoring combinations, and reach each puzzle's target before your turns run out. You don't have to fill every square to win.

A BOOK WORTH FINISHING
Each run spans nine levels and 27 puzzles. Plan around clearly announced Boss powers, then face one of five major final Bosses on the last page. Finish a Book to unlock its next Obstacle difficulty. Every Book keeps its own progress.

MAKE THE NUMBERS WORK FOR YOU
Spend earned coins on Bookmarks that strengthen your build, Markers that reward selected squares, and one-use Buffs for a timely advantage. Make the most of the numbers in your hand, decide when to toss them, and discover combinations that turn a modest move into a much bigger score.

PAPER, PERSONALITY AND ONE MORE TRY
Browse a rotating book rack, turn flexible paper pages, and enjoy gentle music, sound effects and tactile feedback. Adjust the audio to suit you. Interactive practice teaches placement, multipliers, buying and selling, Markers and Buffs. Replay it from Settings, and return to your saved Book whenever you're ready.

Play without a required login. Optional rewarded videos can grant three extra turns, once per puzzle, when an ad is available.

Your next good idea is probably one number away.
