All wooden pieces — Floor cube, Rooftop, Building Permit, Mayor, or Cancel cube — are available if they are not currently on the board and have not been discarded.

Floor cubes: May only be selected from either end of the 3 rows. During the game, every player may auction, bid, purchase, or place Floor cubes of any color.

Rooftops: May only be selected if there is at least 1 building without a Rooftop on the board and there are available Rooftops. Before the auction for a Rooftop, flip over the Rooftop to reveal its number.

Building Permits, Mayor, or Cancel cube: May only be selected if not on the board and not discarded.
