Queens Master

Queens Master is a quiet, thinking-person's puzzle. Place one queen in every
row, every column and every coloured region of the board. Queens are royalty,
so no two of them may ever stand next to each other, not side by side and not
corner to corner.

That is the whole game. Four rules you can learn in under a minute, and 500
boards that will keep you busy for months.

NO GUESSING, EVER
Every board is proven to have exactly one solution before it ships. You are
never asked to guess and then backtrack. If you are stuck, the answer is
already on the board waiting to be deduced, and a hint will point you at the
next square you can prove rather than simply filling one in for you.

A REAL DIFFICULTY CURVE
Ten acts take you from gentle 5x5 grids to 11x11 boards that demand real
technique. Early levels teach forced lines and confined regions. Later ones
stack those ideas until you are reading the whole board at once. Nothing is
padded and nothing repeats.

BUILT FOR THINKING, NOT TAPPING
No timers counting down at you. No moves running out. No twitch reflexes. Take
five seconds or five days on a board, it will be exactly where you left it.
Tap a square to cycle it: empty, crossed out, queen. Drag across the grid to
sweep away squares you have ruled out.
