Royal Smash! - Physics Puzzle

How many people have installed this game, as the storefront reports it. This number is worldwide — unlike the price, the same package answers with the same install count in every market we asked — so it carries no country. Each source below is a different kind of number and they are never drawn on one axis.

Of the eight storefronts we track, only Google Play publishes an install count we can read. Where a store publishes nothing of the kind, this panel shows nothing rather than a zero.
