Rule 01
One queen per color
Every color region gets exactly one queen — no more, no less.
The color-grid star battle brain game
Give every color its crown. Boards are pure deduction — one queen per region, row, and column, never touching — and each has a single solution. Solve today's board faster than yesterday and climb the global leaderboard.
How it works
Rule 01
Every color region gets exactly one queen — no more, no less.
Rule 02
A row can hold only one queen, and so can a column.
Rule 03
No two queens may sit next to each other — horizontally, vertically, or diagonally.
Pure logic
Every board is uniquely solvable by reasoning alone, and grows from 5×5 to 12×12 as you improve.

Questions
Queens Puzzle: Crown Logic is a free iPhone logic game. Every board is a colorful grid: give each color region, each row, and each column exactly one queen, and never let two queens touch — not even at the corners.
By deduction alone. Start with regions that have only one possible cell, mark the squares a placed queen rules out, and keep narrowing. One queen per region, row, and column; no adjacency. Every board has exactly one solution, so no guess is ever required.
