Printable 10x10 Crowns (Hard)

Ten-by-ten is the largest Crowns grid we print: ten regions, ten crowns and plenty of room for long chains of deduction. For experienced solvers.

This first pack has four Crowns puzzles with an answer key on the second page. Each grid has ten colour regions, so ten crowns to place.

How to solve

  • One per line: Each row and each column holds exactly one crown.
  • One per region: Each colour region holds exactly one crown.
  • No touching: Crowns never touch, not even diagonally.
  • Cross off: Mark every square that cannot hold a crown. The last open square in a row, column or region is the crown.
