Secrets Unlock Hidden Cave & Game Type To Unlock the ''Hidden Cave'' you need to buy the map from the shop and begin a Practice game. If you're breaking then you need to point the Cue towards a cave to your right side, facing away from the sea. (At about ''2 o clock'' angle wise). Pause the game and enter the ''Subgame Menu'' and choose the map. You will be whisked away to the ''Hidden Cave'' where you gain $20,000, the use of a special table and also the ability to practice ''Switchball'', a game type invented by Archer Maclean.
