Best under-the-radar bonus round slot

In our humble opinion, Guns N’ Roses is the best under-the-radar bonus round slot. People are attracted to the game for its loaded Guns N’ Roses soundtrack, but there’s a lot more to this game.

There’s more than one bonus feature. Anytime you land three platinum records anywhere on Reels 1, 3, and 5, you trigger the Bonus Wheel, where you’ll win entry into one of three bonus features. The Crowd Pleaser bonus is the one you want.

It’s a pick’em game, but it has multiple levels offering cash prizes and free spins. This slot and its Crowd Pleaser bonus have more than meets the eyes and ears, making Guns N’ Roses our pick for the best under-the-radar bonus round slot.

What is the maximum you can win in a bonus round?

A few years ago, one New Jersey player hit a $489,865 jackpot at BetMGM playing the bonus round on Divine Fortune.

Since the bonus round is where you’ll get a shot at the progressive jackpot on most progressive jackpot slots, the maximum amount you can win depends on how big that progressive grows.

What is the lowest buy-in slot with bonus rounds?

Sometimes, you have to bet the maximum amount on a slot for just the possibility of access to a bonus game, free spins features, and a jackpot. Others randomly award this access with any bet level.

Since you can play a variety of slots with bonus features for as little as $0.01 per payline or bet level, and most slots average 20 paylines, $0.20 is the minimum you’ll need to bet for the chance at a bonus round.

Divine Fortune is one such slot. With a $0.01 per payline minimum and 20 playlines, you can play Divine Fortune for $0.20 a spin. Every spin gives you a chance at the bonus round, where you might win Divine Fortune’s progressive jackpot.
