Crown Blocks

One crown per row, column, and region — none touching. 500 brain puzzles, pure logic, no pressure.

Crown Blocks is the elegant Queens logic puzzle where one crown rules every row, column, and region.

Think you can place every crown? The rules are simple to learn but tricky to master: fill the board so exactly one crown sits in each row, each column, and each region, and no two crowns ever touch, not even diagonally.

No timers rushing you, no clutter, just you, the grid, and that satisfying click when the logic falls into place. A pure black-and-white design keeps your focus where it belongs: on solving.

HOW TO PLAY • Tap a cell to place a crown • One crown per row, one per column, one per region • Crowns can't be adjacent, not even diagonally • Use logic, not luck, to crack every board

FEATURES • 500 handcrafted levels, each with a single unique solution • Difficulty that grows with you, from gentle 4x4 grids to brain-bending 10x10 boards • Clean, minimalist black & white design with dark mode • Smart hints for when you're stuck • Undo any move, anytime

A WORKOUT FOR YOUR BRAIN If you love Queens, Sudoku, nonograms, or any classic brain teaser, this crown puzzle will keep your mind sharp, perfect for a quick break or a long, satisfying solving session.
