Cat Sudoku is a cozy logic puzzle: fill the grid so every row, column and box contains each symbol exactly once, using cute cat-themed icons or classic numbers.
Each puzzle starts with a few symbols already in place. Complete the grid so that no symbol repeats in any row, column or box. The 6x6 grid uses 2x3 boxes and six symbols; the classic 9x9 grid uses 3x3 boxes and nine symbols. Every puzzle has exactly one solution.
Tap a cell, then tap a symbol on the pad below. Turn on Notes to pencil in candidates, use Undo or Erase to fix entries, and tap a filled cell to highlight every matching symbol. With auto-check on, wrong entries cost one of your three lives; turn it off for a classic game.
Every day brings one new 9x9 puzzle, the same for every player. It is easy on Monday and builds up to expert on Sunday. Solve it to earn a bonus hint and grow your streak: reach 3, 7, 14 and 30 days in a row for extra hints. Miss a day and the streak starts again.
Win puzzles to earn hints and unlock collectible cat cards, with rarer cats on harder levels. The Stats screen shows games played, wins, win rate, best and average times for every grid and difficulty, plus your streaks.

You start with three. Every win earns more (two on Hard and Expert), the Daily Challenge adds one, and streak milestones add bonus hints.
