Regal Moss Crowns

Regal Moss Crowns is a quiet logic puzzle about placing crowns on a coloured field.

Every board is an N x N grid split into N coloured regions. The task is simple to state and deeply satisfying to work out: place exactly one crown in every row, in every column, and in every coloured region - and never let two crowns touch, not even at a corner.

HOW IT PLAYS
Tap a square once to rule it out with a small mark, tap again to set a crown, tap a third time to clear it. Crowns that clash pulse in red, so a mistake is never hidden from you. An optional assist shades every square your placed crowns already forbid, turning a tangle of possibilities into a clean chain of deductions.

THREE FIELD SIZES
Choose a 7 x 7 field for a short sitting, the classic 8 x 8, or a 9 x 9 for a longer campaign. Every board is built fresh on your device and then checked by a solver, so each one has exactly one answer and can always be reasoned out. Guessing is never required.

TOOLS, NOT SHORTCUTS
Undo lifts your last tap. A hint places one correct crown, or lifts one that cannot be right. A timer runs quietly if you care about it and can be ignored if you do not. Nothing here rushes you or punishes you for thinking slowly.

KEEP A RECORD
The Stats tab tracks fields crowned at each size, your best time per size, marks placed and your hint-free streak. Twelve awards mark the milestones, from your very first crown to fifty completed fields. Everything is saved on the device and survives a restart.
