I deposited 10 AUD onto 7bitcasino and used the 100% bonus, meaning i had to wager 400 AUD to get anywhere. I did it just to waste some free time.
Long story short, I got feature on aztec gold megaways, on 0.20 bet. I ended up getting 4070x and filled $400 wager up and cashed out 850 AUD. It was insane!
