Since most hacksaw games is limited to 10,000x so I believe this user played NoLimit City because there are so many games with huge max multiplier compared to other providers. Push gaming can be alternative to reach more than 10,000x because games like Big Bamboo and jammin Jars can give few ten thousands multiplier. Extreme volatility slot is the best choice if we are hunting for big multiplier but of course the risk to lose is bigger compared to low to medium volatility slots.
