I'd call that superstitious for sure because it implies that the seed somehow determines if you're going to be a lucky or unlucky players or that the seed can be jinxed.
At least that's how I see it. It also feels like the gambler suspects the system is rigged not to allow too many people to win, so there's some kind of seed monitoring system that doesn't allow players to get too lucky?
I don't believe there's a correlation between your seed ad luck. If there is luck, it is in you not in the seed.
I don't believe in luck that much. I do believe there's a part in the seed though that will give you a multi-win but we don't know when it will happen.
It could be in the 10,000th bet or it could be in the 9th bet.
Last month I had a seed with a record of 400k bets and I can say I made some profits on it because it gives a lot of multi-wins in just a short span of bets. Like in every 2000 bets, there will be a surprising multi. That's also where I got the x1500 multi-win in Tome of Life then x500 and x900 which made me happy so I withdrew those funds.
But, when I used that same seed in other games like Keno and Scarab Spin, I could not even see those numbers of multi-wins anymore. I guess that incident in my betting experience is also a part of what made me curious about the guy who said that in my opening posts.
But we don't have the resources to confirm it so it's just a superstitious belief or a theory.
