Leave some breathing room.
A clear head is more useful than a fast hand when the whole floor needs to fit.
Pause before a large rectangle
The preview is a chance to look, not a deadline to confirm. Trace the edge, count the squares and check whether another clue would be trapped inside. Nothing happens until you place the chamber.
Let a wrong guess be temporary
A blocked area is information about the plan, not a failure that needs to be paid away. Remove the room or use undo. Example hints are available from the start and do not reduce a reward.
A floor can remain unfinished
There is no countdown, daily attendance requirement or saved ranking. Leave when you have had enough. A page reload begins again, so take that into account rather than treating the browser as a permanent notebook.
Keep the controls comfortable
The board uses tap targets and numbered clues instead of requiring a precise drag. Increase the browser zoom for the written guide. Reduced-motion settings quiet the decorative transitions without changing the puzzle rules.
Send a precise observation
When a room behaves unexpectedly, note its two corners, the selected plan and the displayed message. That can help an enquiry stay short and useful. Do not include unrelated personal or financial details.
A quieter page
The device’s preference is always respected. You can also request reduced decorative motion for this visit.
