Fill the 9x9 grid so every row, column and box holds the digits 1 to 9 once. Tap a cell, tap a digit. The grid highlights the row, the column, the box and every cell with the same digit, so you see what is left. Five levels, Easy to Master, rated by the techniques they need, not by the clue count. Notes with auto-clear, a Fill button that writes every candidate, three free hints, undo, a timer and a three-mistake limit you can turn off. A new puzzle every day, the same for everyone, with a streak. Every puzzle earns XP. Player levels open digit styles, themes and paper patterns, up to level 50. Go after 44 achievements and 12 feats, and five leaderboards, one per level.

How to play

Pick a level and tap Play. The givens are in ink, the clock starts at zero.
Tap a cell, then a digit. A correct digit turns blue; a wrong one turns red and counts a mistake.
Three mistakes end the puzzle, unless you turn the limit off in Settings.
Tap Notes to write candidates in a cell. Fill writes every candidate at once.
Hint fills one cell. You get three per puzzle, then one more for watching an ad.
Undo takes back your last digit or note. Correct digits stay.
Solve fast for a bigger bonus. Play the daily every day to grow your streak.

Tap Select a cell, press a digit, tap a tool.
