About Word Sudoku: Crossword Puzzle with Wooden Letter Blocks

Word Sudoku is a relaxing crossword puzzle played with wooden letter blocks. Each board presents a small crossword grid whose answers have been broken into colored blocks, and the challenge is to restore every row and column so that each one spells a real English word. The game spans 300 hand-tuned levels, ranging from 5×5 warm-up grids to demanding 8×8 challenges, and adds a Daily Puzzle that refreshes every day with a calendar for replaying past entries. A built-in Word Book provides simple English definitions for every word built during play, and tricky words can be saved to My Words for later reference. Coins earned through play unlock new tile skins and board themes, while stars collected across levels feed into a leaderboard. Word Sudoku is available in 10 languages.

How to Play Word Sudoku

Every puzzle has exactly one solution. The goal is to drag letter blocks from the tray onto the board so that each row and column spells a real English word. A block only fits a slot that shares its color and shape, so matching those two properties guides placement. Placing a block in the wrong slot sends it bouncing back and costs one heart; lose all three hearts and the level ends. Finishing without any mistakes awards three stars, and a hint is available to place a block automatically when progress stalls.
