If you are playing Soda Crush as well then check out this to see how to get more lives with Soda Crush.
The first thing you want to do before you even read this post is make sure that “Automatic Updates” with apps on your phone is turned off. Once they figure out this bug they are going to fix it so turn it off so you do not get the update.
I cannot confirm this bug works with Android or any other version of IOS other than mine so I am sorry if it does not work for you.
I am currently using an iPhone 5 with IOS version 8.1 (12B411)
If after a while you get to the screen that tells you that you have run out of lives and need to wait or pay .99 cents to buy more all you simply have to do is go back and keep challenging the player. After a couple times of doing this I can eventually play again without paying a dime.
