Looks like these three friends could use your help. They need to destroy the ice crystals that keep appearing before the time runs out. When you start, follow the tutorial of how to play. It is rather simple, just click on the crystal shards or the larger crystals to get points. When you click on one, one of the girls will appear to destroy it. Although be sure to keep in mind that you should try to create chains. The longer the chain of destruction the more points you will get when the crystals or shards are destroyed by the girls.
