Typical of Bgaming games, it is high volatility slot but not as volatile as games by NoLimitCity.
The RTP itself is fair enough which is 96.5%, standard RTP of most slot games.
Anyway, there are still 4 active challenges to hunt but the reward is not as big as this one while the minimum bet is bigger than this one.
They should consider to have more reasonable challenges unlike those challenges to chase 2500x-7500x with few dollars minimum bet.
Yeah, nolimit's insane volatility is next level.
Indeed, at the moment, current challenges are not pretty attractive. Plus with those multi and bet size, there are other places that offer more reward.
I also like their past slots' challengers for the low bet size and multiplier goal. The reward is not as big as the bgaming one but good enough for me to try my luck with a small bankroll.

BTW, does gates 1000's minimum bet size actually go 10c in USD? so far never seen that. unless they accept the USD equivalent of some local currencies.
Thanks for testing and I guess the 15-minute processing time is more likely for Bitcoin because with this blockchain, the average block time is 10 minute. For altcoin blockchains, it's normal to see the processing time is much shorter than 15 minutes.
I don't think confirmation time is also taken into account since bitcoin could take longer depending on mempool condition and fee. The within 15 minute mark is most likely just for when the transaction has been sent out/broadcasted. If there's nothing wrong found in your account and no technical issue/s either, it will most likely take just some minutes.
