Ive hit Wild swarm whilst playing at just £0.40 spins, it paid £328, but i agree with some comments Bonanza can take hundreds of spins to drop for example i autoplayed my way through some 1000 spins yesterday and the bonus didn't drop, however my balance when starting was at £420 and playing £0.40p spins my balance after the mass autoplays was £365 so i was lucky to only lose £55 from nearly 1000 spins. It sucks how its so hard to bonus but its also great that it doesn't cost you the world to try and get it.
