We can assume a lot of things, but the best thing to do is ask the dev about it. A year ago, according to her feelings, it was
like this.

So here I agree with
Maviarab and what he wrote above. Anyway, in addition to the upcoming Ep8 pt2, we have Ep8 pt3 (the final installment of the game show) waiting for us, which Tess hasn't started working on yet. And basically, the “war of all against all” won't start until episode 9+ at the earliest. That is when the first heads of serious players like the Karlsson sisters will fly. (However, it depends on our decisions, and, as Tess writes, we can save the first possible victim among the sisters if we try very hard and make certain decisions).
So, using chess terminology, I'd say we're now in the first half of the
Mittelspiel, which will last (I think) at least until the end of episode 10+, after which we will be waiting for a large and extensive
Endspiel (Ep/Ch 11-12+), the result of which will be ~17 different endings of the game. But, again, it all depends on Tess and how much the creative process takes her over. For example, the new update (Ep8 pt2) was supposed to be smaller, but according to her, she again didn't hold back (lucky for us) and did more scenes than planned. So time will tell.
