Purr Grid

About Purr Grid

Purr Grid is an independent browser game by SailToWorld. Its boards are square grids split into numbered, coloured regions, and the goal is to place one cat in every row, every column and every region. Cats may not sit in neighbouring squares, diagonals included, so each cat you place rules out a ring of squares around it.

The daily puzzle is one board for everyone, keyed to the UTC date and changed at midnight UTC. It is drawn from the game's Standard path and rotated or reflected, so it is usually a 6 by 6 or 7 by 7 grid. Finishing it adds a day to a streak kept in your browser, and a Copy result button gives a spoiler-free summary with your time and how much help you used.

Outside the daily board there are 72 original levels in three paths: Beginner boards solve with single-candidate steps, Standard ones add groups confined to rows or columns, and Challenge boards need assumption checks. A Mix button rotates or reflects a board from a path for a fresh layout at the same difficulty. Every board is checked by a solver to have connected regions and exactly one solution.

What sets it apart from other Queens-style games is its teaching help. Show a reason highlights the next deduction and explains why it follows without placing a cat for you, and Reveal a cat is counted separately. There is a guided mini lesson and a strategy page with worked deductions. No account or payment is needed, and progress stays in your browser. It suits players who like LinkedIn's Queens or Star Battle and want a calm daily board with explained hints.

How to play Purr Grid

1. Open the daily puzzle page; today's board is labelled with the UTC date.
2. Choose the Cat tool and tap a square to place a cat, or tap it again to remove it.
3. Switch to the × Mark tool to tap or drag across squares you have ruled out; right-click also marks.
4. Keep exactly one cat in each row, each column and each numbered coloured region.
5. Never place two cats in neighbouring squares, including diagonal corners.
6. Use Show a reason when stuck to see the next deduction explained, then copy your result when the board is solved.

Tips

• Start with the smallest region: if a region sits inside one row or column, every other square in that line can be crossed out.
• After placing a cat, mark all eight squares around it at once; the Show excluded squares option does this visually.
• Look for two regions confined to the same two rows: no other region can use those rows.
• Show a reason does not count as a reveal, so use it to learn a step rather than revealing a cat.
