I sure have and still do!
I am up to about 350 and keep vowing I will not play again.
Sometimes it took me months to get through one level and at one stage I DID stop playing because of this but then one day i tried again and got through that level.
This has happened a few times but at the moment, as they have a free spin and prize every day, this has helped me get through levels and, touch wood, I have not been stuck for about a month now.
YAY Candy Crush!
I do not believe in paying for things on this game even though I used to as I thought $1 is not a lot -worked out they are making probably millions per day.
I paid often as I thought $1 for the enjoyment I get out of it is nothing.
I still feel this way but I do not like the company -King, so now I will not pay!
