[] Arcade: Tornado Lock (and unfixed jumping layer)

In Tornado, the game can be locked in gameplay forever by clicking two times rapidly immediately after starting the game. This can be used to grief other players, preventing them from playing this game. The ball will stay in place, never leaving the plunger zone.

The ball may also jump out of its layer. The ball appears to go further into the labyrinth. It then pops back out into an outer layer, causing the player to receive less tickets than what was believed earlier.
