How to play
Tap a cell, then tap a number to place it. Each row, each column, and each 3x3 box must contain the digits 1 through 9 with no repeats. Use Notes to pencil in candidates, Hint for a safe next move, Undo to step back, and Solve to watch the tea-house bot finish the board.
Difficulty levels
Choose from Gentle, Easy, Medium, Hard, and Expert. Every puzzle is generated fresh with a single guaranteed solution, so there is always exactly one right answer and never a dead end.
