List of the best bonus buy games from hacksaw imo. 

1. sixsixsix No point to give the game basegame spins, really impossible to hit the bonus. With the buys if you land 3 red bonus marks usually it hits at least 100x. The multiplier system can make the win go from 20x to +1000x so easily.

2. Rise of ymir 4 scatter After you get the collector you actually only need to land 3-4 wilds to make it pay.

3. Hand of anubis 3 scatter Just a very nice game to watch and always seems to give some decent hits.
