What do you need to do to earn the star in Peggle Blast Daily Challenge?

If you have a level where you have won only 1 star, you replay until you have more than 1 star.  Any level where you get stars will do.  If you have 3 stars in all your levels, play a new level and only win 1 star, and then play it again to get 2 or 3 stars.  Good luck

Apparently for the daily challenge only increasing stars in a previously worked level counts. Stars on first time win of levels does not count for the daily. I do not know what would happen if you had all levels at 3 stars — and I never expect to find out as there are several levels that I cannot figure a way to get all stars.

I’ve earned 3 stars in every level from 1-30, and several beyond level 30.  When I went back to play level having only 1 or 2 stars, I found it easier to earn more stars just by replaying those levels 2 or 3 times.  It depends on how the orange pegs are arranged.  Some of the skills used in the earlier levels really come in handy in the later levels.  Don’t forget to bounce off the side walls, either.  Earning extra balls helps also.  The green pegs will give extra balls, or power ups depending on what level you are playing.  Hope this helps.
