Kitten Square: Sudoku Puzzle

Kitten Square is a logic puzzle with a single rule: the same cat never appears twice in any row or column.
That one rule carries the whole game. The first boards are small and gentle, and every level, right up to the big 9x9 grids, can be solved with pure deduction. No guessing, no luck.
HOW IT PLAYS
• Tap an empty cell to pencil in a note, double tap to place a cat
• Wrong placements bounce off, so the board never gets ruined
• Three hearts per level, instant retry when they run out
• Stuck? The hint shows the one cell that can only hold one cat
WHAT'S INSIDE
• Levels that grow from quick 4x4 warmups to full 9x9 boards
• New kittens join the crew as you play — collect every set
• A daily ranking to climb, one solve at a time
• Pencil marks, missing-color dots and other helpers you can toggle
• A warm cream look, plus a dark theme if you prefer
QUIET BY DESIGN
No move timer, no energy system, no account. The whole game works offline, so it travels well: planes, trains, waiting rooms.
If you enjoy sudoku or queens-style puzzles, you'll settle in fast. If you've never touched a logic puzzle, the first few levels teach you everything.
