I'm watching the anime on netflix right now because the second season is there, I've started it and the season is over now and I'm wondering if there's another one coming
So far nothing known.
OK, well, hopefully something will come
It's from June 13th. Only when they see how it works, it is decided if there's a sequel. You'll have to wait there.
OK, if you hear something just write in thanks
Kakegurui is based on a manga and the anime practically caught up with him. These are the last 2 episodes of the anime only filler (so fictitious). More specifically, Rei's existence in the anime is fictitious to lengthen the anime so that enough material is enough for a second season.
For a third season you have to be patient for a very long time.
Alternatively, I recommend you just read the manga from Chapter 55, Volume 10, even if not much further.
An announcement for a third season you will find out at the earliest
