Botta's Architecture is a collection of Wheel of Fortune buildings that can be accessed through the Extra building menu and is available for a limited time.
Each spin of the wheel usually costs 3 (1 when rerun) and provides one random building from the collection. Once a player obtains all of the buildings in the collection, they receive the Reward Building. Because the wheel is random, it is possible to obtain the same building multiple times. However, if a player receives more than one copy of the same building, those buildings can be sent to a friend as a gift or can be sold. Buildings received as gifts count toward the completion of all buildings for the purposes of obtaining the reward building.
Once the Reward Building is obtained, the user can re-spin the wheel for additional copies of the random building, or purchase additional copies of the reward building for 7 . In addition the Wheel of Fortune will remain permanently in the Extra section of the Shop Menu.
