Japanese megahit Monster Strike is done in North America on August 1

One of the most lucrative games ever released for smartphones is coming to an end — at least in its English form.

Developer Mixi revealed today that it is shutting down the English version of Monster Strike, the mobile arcade-style role-playing game where you fling balled up monsters at one another in combat. While the game is still the No. 2 highest-grossing app on Apple and Google app markets in Japan, it has failed to replicate anything close to that ranking in Western territories. That relative lack of success directly led to Mixi deciding to turn out the lights on August 1 — although, players will no longer have the option to download it beginning July 2.
