Queens

Place one queen on every row, every column and every colour region

of the board, without letting any two queens touch - not even

diagonally.

That single rule is the whole game. No timers forcing you, no lives

to lose, no moves to buy. Every puzzle has exactly one solution, and

that solution can always be reached by reasoning alone. You will

never have to guess.
