Once there was no limit about the counter when you pass that 1,999,999,999 coins, it would display odd characters which are letters and symbols. They added the limit after some people noticed it. The more the number increases, the smaller it has to be to be shown in screen. If you compare 1,999,999,999 coins with 2,000,000,000 coins, the number "1" is narrow but "2" is wide number. So these odd numbers begins from here where the game can't show real numbers anymore.

The game gets updated in the same way for PC version, no matter you use a phone or a PC. It is possible to make the counter count higher on PC but they do not care PC and PS Vita versions. They just use same settings for every platform.
