Hi Steven! I think you´d enjoy Hippo Pop. It is a cheap bonus buy in which you can gamble from 5 to 7/9/12 spins. The bonus has expanding megaways and multiplier. I will even recommend you to try and a couple of rounds and just spin it to the bonus. Sounds dull I know, but this way it lets you have the possibility to get up to 7 spins for free. Give it a go.
