Strategy Tips

Start with elimination. Mark cells with X where queens definitely can't go. This often reveals where queens must be placed.

Look for singletons. If a row, column, or block has only one valid cell remaining, that's where the queen must go.

Use the corners. Corner cells and edge positions are often more constrained, making them good starting points.

Think about adjacency. When you place a queen, immediately consider which cells it eliminates in neighboring rows and columns.

Don't guess. Every Queens puzzle has a unique solution that can be found through logic alone. If you're stuck, use a hint!
