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 the entire Lapland. Huge amounts of colored ice started growing in most inappropriate places and interfered with the normal life of Lapland inhabitants. But Santa never gives up! This had happened quite a few times in the past but all the people in Lapland know the properties of this snow. 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 coped with the disaster before. And Santa decided to use this good old method this time as well. Besides, it is a good opportunity to test the new model of his sleigh that had just been developed in the scientific laboratories of Lapland. Under the pressure of constant protests from those concerned with animal rights, they had developed a special sleigh for Santa. No deer are needed for this sleigh, it flies using the energy of that very magic ice! Help Santa! It will be difficult for him to do away with all those ice blocks alone. Moreover, the supply of magic ice in the sleigh is limited. It is still an experimental model and there is a lot to be done yet. You will need to be very clever to deal with it. But you'll make a perfect team, together with Santa! Well, the sleigh is fueled and ready to fly and Santa waits for you only. Good luck!
