Ive been playing Rune Gems for several now, and I am still not bored. I have passed all levels without purchasing any extra helps...it just takes patience. Eventually the game will give you a set of gems that will work. The more you play, the quicker your eyes will catch matches and be able to see future matches buried within the stacks of gems. I purchased the additional levels and passed all of them, too, without purchasing helps. Now I am trying to increase my number of stars earned at each level. I think the key is to just relax and enjoy the play. If the game doesnt give you a set of gems that work, hit "restart" and play it again. It may take a week of playing in your spare time to get a set that is winnable on the hardest levels, but thats ok by me. Im not in a hurry to get all the stars for each level.
Lets see more levels soon!
