Just managed to get past level 31 after being stuck for over a week!!! I found the thing to do was to try to get the special candies, and try to get them next to each other for an extra boost and it all seemed to happen on its own!!! Mi just happy I got past it!,,,,

Im at level 169 and i helped my friend reach level 148 in a matter of weeks. i think the biggest trick to them all is learning how to create special candies and try to combine special candies foremost. also many harder levels i find if you focus on crushing candies at the lowest lines possible, that way all of the above candies will often crush atomatically. just a few tips that help me

I can't get pass level 21 :-(

I am on level 31 also and don't understand how to clear the jelly.......Anyone know how to do it?
