Done ✔ I didn't change the client seed, I used the default one. It represents 10 000 bets on Hi in a row. And as expected I only lost around 500 sats (554 precisely) at the end. I don't know what is wrong with you, but I don't believe you anymore when you claim you always get 15% of loss.
Lucky. Now try to bet on other multipliers (x3, x5, x10, x1000 and x4750) only then you will see that the House Edge is more than 5%
