For sure, Hacksaw games are very hard to hit, and even if you got a bonus round, it's not a guarantee. I even had to be very happy if I hit a bonus round, but they've all dead spin unlike others who hit big multiplier with just one single spin.
My advice as a former player who has experience with Contest Multiplier. You can tried to play on the slot are not high volatility, maybe chasing around multiplier up to 100x to secure some entries. If you chasing to the slot or provider are really high or extream volatility like HackSaw, Push Gaming or maybe crazy extreme volatility like No Limits your balance can be doomed before you can get a good multiplier.
