King’s Bubble Witch Saga 3 (Free), the bubble-busting cousin of Candy Crush Saga, is celebrating Halloween with a first: during this live event, players can play collaboratively. Starting today and up until November 1st, you’ll have to help Stella the witch (appropriate for Halloween) and brand new characters get their candy back from that bad kitty, Wilbur (although I’m sure he’s actually more misunderstood than anything). In this new collaborative mode, you have to join forces with others to pop as many bubbles containing Halloween candy as possible, and the more treats you all gather, the more rewards you’ll get. And if one player loses a level, a team member can recover those lost candies. No candy left behind for sure.

In addition to this collaborative event, King is using Snapchat to enhance the celebrations. For the first time ever in the history of Snapchat, you’ll be able to unlock lenses and filters through another app, in this specific instance Bubble Witch Saga 3. Depending on what level you get to in Bubble Witch Saga 3, you’ll get to unlock exclusive Halloween-inspired lenses and filters for Snapchat. It will be interesting to see if other developers being to take advantage of Snapchat in similar ways given how popular the service is. Enjoy busting Halloween bubbles.
