More about this game
Queens Logic Puzzle challenges you to place a set number of queens on a grid. You must place exactly one queen in every row, column, and colored region. Queens cannot share a row, column, or region, and they cannot touch diagonally. The game features 6x6, 8x8, and 10x10 grids, tracking your completion time and daily streak. A puzzle ends when you successfully place all queens with zero conflicts.
Tips
- Start by finding small colored regions; if a region only has one or two cells, it limits where a queen can go.
- Use the X mark generously to rule out rows and columns that already have a queen.
- Watch for the red pulse on a queen—this indicates a conflict you need to fix.
Questions
What do the colors mean?
The grid is divided into colored regions. You must place exactly one queen in each colored region.
Why is my queen pulsing red?
A red pulse means the queen is in conflict. It either shares a row, column, or region with another queen, or it is touching another queen diagonally.
What does the Quick X button do?
The Quick X button changes your tap behavior. Instead of cycling through empty, X, and queen, tapping will only toggle an X mark on or off.
