Bill's Sudoku
Calm, classic Sudoku with a Japanese touch: a wooden board, shogi-style number pieces, and gentle café jazz.
What’s in the game
Easy and Medium are free in your browser, for as long as you like. Hard, Expert, and more come with the app: free for 30 days, then one small purchase, forever.
Four difficulties
Easy, Medium, Hard, and Expert, each with its own feel and a clock on every level.
Notes and hints
Pencil in candidates, ask for a hint when you are stuck, and undo as far back as you like.
Kanji numbers
Switch the pieces to kanji for a quiet change of pace, like a Japanese newspaper puzzle.
Records and leaderboards

How to play
Three steps and you’re in.
Pick a difficulty
Start with Easy. Every row, column, and 3×3 box needs the numbers 1 to 9 exactly once.
Place the pieces
Tap a square, then a number. Turn on Notes to pencil in the numbers you are still thinking about.
Finish the board
A full board with no clashes ends the puzzle. Solve it with no hints and 3 mistakes or fewer to put your time on the Leaderboard.
