This map is the similar to Map124 - the only difference is that the long dynamic block consists of ice instead of wood. There is no shaman on this map.
Don't hesitate, decide for one direction and walk there. Most of the mice walk right, so it's often more intelligent to walk left. The piece of ice will fluctuate and finally fall off - watch out, it's not wood, it is ice, which is a lot more slippery. The one who gets first is usually one of the ones who picked the side that less mice went on. Being ice makes it easier to jump into the hole after the plank falls.
