I don't know if luck is supposed to make such a huge difference in the Castings minigames or what, but I was playing Match 3 and with almost 40 seconds left to go the game gave me a position where it was impossible to continue. I feel that had the game not gone into an unsolvable position I could have gotten a score higher than that of two other people in my game. The people making these games should avoid allowing positions where the player cannot progress. It is very frustrating.
