QueenSweep

QueenSweep is a daily logic puzzle that fuses the N-Queens problem with Minesweeper-style number clues. Your mission is to find all 8 hidden queens on an 8×8 board using deduction alone.

Each puzzle starts with a blank grid dotted with numbered cells. Those numbers tell you how many queens touch that square, including diagonals. Your job is to figure out where all 8 queens are hiding. The catch? Every row and column must contain exactly one queen, and queens can never sit diagonally adjacent to each other.

• Click to place a flag where you think a queen is hiding.
• Numbers show how many queens touch that cell, counting all 8 surrounding squares.
• Each row and column must contain exactly one queen.
• Queens cannot be diagonally adjacent, though they can share a diagonal line with empty space between.
• Mark cells with X to eliminate possibilities as you narrow things down.
• Flag all 8 queens correctly to win.

The daily puzzle changes at midnight, with difficulty ramping up through the week. Mondays are gentle, weekends are ruthless. Unlimited mode lets you practice anytime with custom difficulty levels.

Why we like it:

• ✅Scratches the same deductive itch as Sudoku, but with fresh rules to master.
• ✅Puzzles are quick enough for a coffee break but tough enough to feel earned.
• ✅No guessing required, just pure logic all the way through.

Hint: Start with rows or columns that already have several revealed numbers. A cell showing zero means no queens touch it at all, which instantly eliminates eight squares. Use those to cascade through the board.
