cant get past 86. i will not buy. Is that the problem?

This is how King make their money. They put level in that are almost impossible to pass, at the end of the day you get that frustrated with the level that you end up buying. This is repeated through out the King games. Persevere or buy... Up to you. My advise is to wait till you get a good game. You will eventually pass it but it could take awhile. Good Luck
