Queens Unlimited

Endless Queens, four levels

Every press of New puzzle draws a brand-new grid that has never been played before. Each one is checked to have exactly one solution you can reach by logic.

• Easy: 6×6 or 7×7 grids that open up quickly. Great for learning.
• Medium: 8×8 grids that need a little thought about how regions sit in rows and columns.
• Hard: 9×9 grids where you'll need to reason about groups of regions together.
• Expert: 10×10 grids that sometimes need a short "what if" chain to crack.

Every unlimited puzzle has its own link, so you can send a friend the exact grid you just solved and compare times. Your best time per level is saved on your stats page.

1. Place exactly one queen in every row and one in every column.
2. Each coloured region holds exactly one queen.
3. Queens may not touch each other, not even diagonally.
