About
One familiar idea, expanded.
Choose 1 Queen or 2 Queen mode, then solve Easy, Medium, Hard, or Extreme boards. Each row, column, and colour region has a target quota, and queens cannot touch in any neighbouring cell. Progress, best times, streaks, and statistics stay on your device.
The first 50 levels in every mode and difficulty are free, giving you 400 puzzles to start. One hint and one check are free on each puzzle; rewarded ads unlock more help or one locked puzzle. Difficulty packs and Full Access are one-time purchases.
