EDIT: Thanks to the good people of r/AndroidGaming I found out that this is just some kind of a loot box from an otherwise free to play game. The whole setup looks now a bit scammy, so check out the deal carefully and don't get tricked.

CashKnight (Soul Event Version) is an idle RPG game that is currently on an insane offer. For the next six days, you can get it for free, even though it is otherwise - $9,99! Yes, SUPERCLAY Inc. development studio is selling its Android idle game for 10 bucks and it must be good, behind that so far, it has over 100,000 players.
If you presume that even 10 percent of these 100k players paid for the game (which is about three times as expensive as the regular premium gaming app) it must be, as they say, helluva good. The reviews tell a similar tale. So far, it has over 4,400 of those with an average score of 4.5 stars. In fact, almost 90 percent of the reviews are 4 or 5 stars. This is a stunning result for a game that is this pricey.
Use this opportunity - head to the CashKnight Google Play page and save $10 on a clearly very good RPG game (unless my data scapping is all wrong here).
