Width auto-suggests a roughly square board from the square footage — edit it yourself any time you want a different shape (like a narrow walkway).

New tiles land centered and selected so you can see them. Any angle counts as the same size — a 12x24 laid sideways or on a 45° diagonal is still 12x24.

Selecting tiles
Click a tile to select it. Shift-click to add more to the selection, or drag a box over empty board space to select everything inside it. Drag any selected tile to move the whole group together.
