This achievement is very easy to get at level 9 ...
At this level you always give away the 2 glaciers which can be used at any time to push enough scoring.
At this level I have come to get to 372,000 points.
If you manage to get on board another glacier you can combine for achieving 5 double glaciers.
I will leave a video demonstrating more or less as it should do, it is not that hard but it always helps guide one video.
I know that the video does not help much as the levels are totally random, but it helps to get the achievement.
Thanks to youtuber GameWalkDotNet for making a video of the level 9 to get 3 stars and a big score.
