Featured Queens boards
A curated set of 45, named and sorted from gentle to punishing. 0 / 45 solved
Why a set list instead of random boards
Unlimited mode hands you a fresh board whenever you want one, which is perfect for a quick session. This list is for people who would rather work through something with a beginning and an end. Each board has a name, the set runs from easy to hard, and the counter at the top keeps score of how far you have got.

How the difficulty is set
A Queens board always starts empty, so difficulty is not about how much you are handed. It is about how many crowns you can work out at once. Easy boards usually offer several at a time; hard boards keep coming down to one square in the whole grid, which means checking every region, row and column to find it. Every board, at every level, is checked to have exactly one solution reachable by logic alone.
