Being stuck for a while on iOS was its initial problem.
The Android port took quite a bit of time to happen which means 2048 had time to eclipse it for many people. And when it finally was on Android, It probably struggled more there for being a paid game when 2048 was free with ads what’s wrong with you people, it costs as much as 2 coffees and ads are fucking annoying.
It’s been available on both iOS and Android for years before Arcade was a thing.
