Ice Jam

While Santa was busy with his Christmas duties, there was a very strong snowstorm in his magic land.

The storm was so strong that it reached into the deepest caves and spread crystals of magic ice from those caves over entire Lapland. Then huge amounts of colored ice started growing in most inappropriate places and interfering with the normal life of Lapland inhabitants.

But Santa never gives up! This had happened quite a few times in the past and all people in Lapland know the properties of this ice. If you put three or more ice blocks of one color together, the excess of magic tension will make them blow up. That's the way they used to cope with the disaster before. And Santa decided to use the good old method this time as well.
