This is from my experience, from a provably fair game, for example, what can I recognize from that number? until now I (personally) never understood what the pattern was like. but for me it will be different from poker in that I can still take up the challenge because I can see a pattern on the cards. this is what makes me agree that, if we do not have knowledge about a game for what we follow a challenge that exists?
You can't find a pattern on pure chance games. I believe comment from @shoreno was about challenges like "guess the wager" and "guess the slot," in which you can get better after several trials. Furthermore, it's free so only beta would complain about the difficulties. LuLPretty much like what @arallmuus said.
Can I use a VPN service at this casino?
Usually, it's forbidden from the ToS, but you can always logout and play for free using VPN. You don't have to log in if the sole purpose just for the "guess the slot."I tried using chrome with a VPN, my browser stuck on Roobet logo.
VPN works on this site, probably because of maintenance.
