I transfer my money from my PKR Poker account, 50$ each time I want to play and only play with that, never reload. Each time I make a nice win I transfer it all back to my poker account including my winnings.

You might not like that slot, have a go with fun money and see if you like it. Will also help you understand how it works with the bonus rounds and scatters.

BTW I limit my play to once per week/fortnight, it's quite addictive for me.

Have fun.
