In this set, players must repair the breaking machines. A machine will fail 60 seconds after it as broken, with too many failed machines causing the game to end.

To repair a machine, the player may be prompted to solve a simple math problem, stand still for a moment, or do simple trivia. What the machine wants the player to do will be displayed to the player through in-game Chat.

To make this tougher, there are broken pipes that have steam coming out of them in the shape of bubbles. If the steam touches the player, it lowers the player's walking speed until they walk out of the steam zone.

There are also exit workers, who will do nothing unless they bump into the player, at which point they will display a short message in the form of a chat-bubble and make the player unable to move for a few seconds.
