So I was going through the sales figures for Shovel Shuffle, which includes the number of downloads since it's free to play and I made another chart. It shows downloads per region as a percentage, where all regions combined make 100% and a region relates to where in the world the game is available.
As of June 2014 Shovel Shuffle is also available in Austria, India and Switzerland. I haven't include these in the chart since it would skew the results. Unfortunately players in those regions were never able to taste success on the scoreboards because they were patched out in the same month.
