I played about 20-25 games today at an arcade today. I found 2 shots to be extremely difficult, the milk jug and the lock loop for the chest. I feel like the lock loop for you have to have not only some skill but some luck. I want to know if it is really that hard even after you have played the game a couple hundred times. I had no games where i got 3 balls into the lock mechanism and to get into milk jug was luck. I guess you have to be perfect off the end of the right flipper. Someone post and let me know. I was thinking of purchasing it. Anyone unhappy with the purchase because it is too challenging or like with any pinball machine it gets easier as you play it more?
