I don't think you can! The thing is, you just can't quit at all without loose g a life no matter what. But I am not a very experienced player so maybe someone else would have a good solution.Β
There are quite a few players in Candy Crush Saga (I think this is the only game where you can do this) - where you can exit before actually moving any candies and go back into the level again before you play it without losing a life.Β However, @GeraldineNaicke - there were some players who either never could do this or had this ability and then had it removed. It works like this - you go to a level and press play, however before you actually move any candies you hit the pink wheel in the lower left corner and then the door with the arrow pointing to the left and you then exit the level.Β You can then press play again and repeat until you have a game set-up you like (for example two CBs together). So if when you try and use the door to exit (before you have moved any candies) and it says you will lose a life, then you do not have this ability.Β However I know that some people are willing to lose a life to try and get a better board set-up and make sure they get lots of lives from friends so they can afford to lose a few lives in order to have a more favorable board - especially for the more difficult levels.
Thank you @SagaR - i try to be clear enough so players can follow what I am saying and hopefully either answer their question or help to resolve an issue.π
