Probably it's the combination of bad luck and a harder game. Should I continue the experiment or move on with usual 5,000x max-win games for the sake of my sanity?
If you have the money to continue by all means continue.If not I think there are better chances in 5000x games.I know this from my latest personal experience,I tried Coils of Cash with 30000x max payout and the game was boring and the payouts were really small,way different compared to 5000x games where I have won and not only one time payouts of more than 1000-2000x.However with games like Coils of Cash with 30000x payout,once you break your bad luck you turn things around as you win really big amounts of which we all dream about.
