The players co-operate to empty a vault of gold before the time is up. The laser locks have to strategically be opened and closed according to dice rolls, so the carts can move between the vaults. The elevator also has to be moved up and down several times to get all the gold out. The same dice control both the locks and the elevator, so the most efficient use of the dice has to be quickly chosen upon. When in turn, a player always rolls the two colour dice. A die can be used to open or close a matching laser lock on the track, or to move the elevator to the next level, if the colour matches. Further, the player can move their own cart along the tracks on their turn. They try to open a way to an opened vault with gold, and move there to load their cart. With a loaded cart they try to move to the elevator console in the middle of the board, and unload the gold off their cart there. When a cart is being moved, it can move freely along any tracks, until its way is blocked. A free app needs to be downloaded for full play. The app functions as a timer, but also tells the players when their (non-player) partners on street level have managed to open a new vault. Gold can only be fetched from the opened vaults. The elevator can only take 3 gold pallets at a time, and 12 pallets need to be brought to street level, before the time is up. If the players manage to bring up the 10th-12th pallets before the time is up, they win! If the 15 minutes are up before that, the players lose...
