Yeah better than usual bonus. It seems to pay just above bonus gaurantee usually. As already mentioned it has potential but it’s that one bonus in a blue moon bonus. I have had load of extra spins in one bonus and get nothing from them which I think is pointless but that’s part of the game.
Once every three blue moons you’ll get a spin in the bonus with all 4 wilds which is when it gets tasty. Only had that magic spin happen to me twice, but there was never a rhino on reel 1. One day….
