Gotz's Traps Mini Game

Early in the game you will meet an Orc named Gotz.  He will be playing with some small stones in a little room just past the Imperial Quarters on B1.  He'll tell you about his dream to build a labyrinth inside a labyrinth and will give you a Labyrinth stone.  When you leave and come back later on, he will have you disarm a trap.  Do it, and he'll give you a magic stone.  He will then show you a little rinky-dink trap that he made, and tell you that he estimates that it will break after 10 disarms and asks you if you want to try it for 1000G.  Do it, and he'll give you a prize of 3 Transfer Potions.  As you progess further in the game, go back to him again and he will have a 2nd set of traps he'll want you to disarm for 2000G, and another prize.

The traps work basically like this:  you can't get to the next level until you've beaten the previous one (which is kinda obvious).  You must beat one level, leave the floor, then re-enter again and go to Gotz's, and he will have the next level available.  Beat that one, leave then return and the next one is up.  They cost progressively more and more per level (1000 G x game level).  For the ones that give multiple prizes, Gotz will check to see if you have enough room in your inventory before he will let you try for it.  If not, he won't let you.  They are as follows:
