## What is Ruffdoku?

Cat person or dog person? Either way, Ruffdoku is your new daily logic fix.

Place exactly one adorable pet on the board so that every color region, every row, and every column has just one — and no two pets ever touch, not even diagonally. Every puzzle is solvable by pure logic. No guessing, no luck — just the satisfying click of deduction.

• A fresh DAILY CHALLENGE every day — build your streak and earn Perfect Solve badges
• 100 hand-crafted LEVELS that grow from cozy 4×4 boards to brain-bending 10×10
• Pick your side: Team Meow or Team Woof — switch anytime
• Mind your treats: three per puzzle, lose one for every wrong placement
• Beautiful, share-worthy result cards to show off your solve
• Quick to learn, hard to put down — perfect for a coffee break

No sign-up. No clutter. Just you, the board, and very good pets.

Can you keep your daily streak alive? Start solving.
