Shadowverse

And they were supposed to last until the end of July :)
It's just that the developers have become so greedy that they ended the event two days early and extended it for a month, without mentioning it on the website or in the game client, only sending a notification to mobile devices, so that people wouldn't have time to farm enough rupees. I can only applaud them - their level of disrespect towards players is only surpassed in this universe by Russian developers.
