Well, I am way into 276k bets on Plinko with no 1000x win... so do not think you must hit it soon. Some people seem to think that you should regularly change seed, if you do not hit it within 40k bets, but I tried that.. before this and I just get the same result.
Gone are the days where you kind of had some guarantee that you will hit a 1000x within a maximum of 80k hits.

I have dug the hole so deep now... I just have to continue until I hit it... so that I can recover some of my losses.

I feel for you. 275k is insanely lot. May i ask what's your win/loss ratio on plinko?
But weird as it is, thats probability for you, there are some players that got really lucky against all odds, so there must people people who got wildly unlucky against all odds as well. You just got the shortest draw. I feel like there should be some sort of consolation price when you are being really unlucky. Like leveling up faster or something.
