- The O.T.T.O Hut is a building unlocked at Builder Hall level 9.
- The O.T.T.O Hut does nothing when initially built, and will only serve as a distraction defensive-wise then. However, it houses the O.T.T.O which can only become active when the O.T.T.O Hut is upgraded to level 5.
- Upgrading the O.T.T.O Hut does not take time or resources, but instead a certain prerequisite must be completed (and the Master Builder must also be available to upgrade the building). To upgrade the O.T.T.O Hut to level 5, four such prerequisites must be satisfied.
- Once the O.T.T.O Hut is upgraded to level 5, O.T.T.O is activated and functions as an additional builder in the Builder Base. The Master Builder can then freely travel between the Home Village and Builder Base as the player so chooses, whenever he is not working on a building, and can function as an extra Builder in either base as long as you have the Master Builder's Hut built in the Home Village.
- Icon Descriptions
Tapping this icon displays information about the O.T.T.O Hut, such as Hitpoints and information regarding the tasks needed to upgrade the Hut. Tapping this icon also opens up the information screen, and allows the O.T.T.O Hut to be upgraded to the next level, if you have completed the relevant task and if the Master Builder is free. When the O.T.T.O Hut is at maximum level, this icon is not shown. Tapping this icon moves the Master Builder to the Home Village. This icon is only shown when the O.T.T.O Hut is at maximum level and the Master Builder's Hut has been placed in the Home Village. Tapping this icon informs you that the Master Builder is already in the Home Village, or that the Master Builder's Hut has not been placed. This icon is only shown when the O.T.T.O Hut is at maximum level.
