Crown Logic: Queens Puzzle

Place one crown in every row, every column and every colour area. Crowns never touch, not even corner to corner. Every board has exactly one answer, and you can always reach it by logic alone.

Crown Logic is a calm logic puzzle with a royal cat, Princess Pumpkin, to keep you company. No timer, no rush, no ads.

How to play

• Tap or click a cell once to mark ✕ where a crown can't go, twice to place a crown.
• Drag to mark many cells at once.
• A short walkthrough shows the rules before your first game, and Pumpkin guides you through level 1.

What's inside

• Boards from 5×5 to 9×9, and levels that never run out. Every fifth level after 20 is a tougher one.
• Royal Scrolls show the next logical step, with the reason. Royal Leaps fix mistakes and place two crowns. Cat's Paws take back a clash.
• Earn 1 to 3 crowns on every level, travel a painted map and unlock new crown colours.
• A new Daily Puzzle every day, with a streak and a weekly gift.
• Colour patterns for colour-blind players, optional auto ✕, and separate music and sound switches.

Completely free

• No ads and nothing to buy. Out of scrolls or leaps? Refills are free.
