I hate having to build up 2800 coins to unlock more packs which only give you around 1000 coins back. (Even zoomed in the larger puzzles pieces are too small) I play this with a friend across sea's to see who can do the most in a week. If it wasn't for this I would have uninstalled this game already. It does have some good Quirk's. Being able to zoom into one corner and given the pieces for the part works really well especially for the larger puzzles.
