Monopoly (game)
The game only comes with 32 houses and 12 hotels. If the Bank runs out of houses or hotels, no players may build any more of them until the Bank gets more of them (for example, if players sell them or exchange houses for a hotel). If there are only a few buildings left in the Bank and more than one player wants to buy them, the Banker must sell them at an auction to the players who want them.
