Installs
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.

Google Play shows “1,000,000+” on the store page.
Play publishes a precise install counter alongside the rounded step users see on the store page. This is that counter, worldwide, as it stood each day we asked.
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.
