Napdoku: Cat Sudoku Puzzle

Napdoku is a calm logic puzzle with sleepy pets. The board is split into colourful cushions, and every pet needs a cushion of its own. THE RULES • Put exactly one pet in every row, every column and on every cushion. • Pets never touch, not even corner to corner. • Every puzzle has exactly one solution, and you can reach it by logic alone, without guessing. HOW TO PLAY • Tap a cell to cross it out. • Double-tap a cell to put a pet to sleep there. • Drag across cells to cross out many at once. • Auto-cross marks the cells around a new pet for you. WHAT IS INSIDE • Endless levels, from small 5×5 boards up to 10×10, from easy to expert. • A new daily puzzle every day, with a streak. • Hints that show the next step and explain why it works. • Three hearts per puzzle, or relaxed play with hearts turned off. • 12 pets to collect: cat, shiba, bunny, capybara, panda, fox, hamster, penguin, koala, red panda, duckling and bear cub. • Undo, restart, an optional timer and statistics. • Works offline. No account, no sign-in. • In 17 languages. This kind of puzzle is also known as Queens or Star Battle: sudoku-style rules with minesweeper-style deduction.
