Miami Mayhem™ Slot RTP, Details & Wager Limits

Miami Mayhem™ slot is a 5-reel 4-row machine with 14 fixed paylines. As with most regular online slots, create wins by landing 3, 4, or 5 matching symbols on adjacent rows, from left to right.

You can join the mayhem at stake between 10p and £100 per spin. Keep in mind that bets can sometimes cap at £50 depending on the variant available at your preferred Miami Mayhem™ casino. Players outside UK slot sites can activate the autoplay function and turbo mode for fast spins.

The default Miami Mayhem™ RTP is 96.35%, a touch above average, but still won’t outrank the highest RTP slots out there. Besides, lower variants of 94.34%, 92.17%, and 86.23% are also available, so shop around for the top return value.

With a hit frequency of 33%, expect wins on the third spin on average. This is quite impressive for a volatile gameplay, rated 4 out of 5 on the scale. Hacksaw Gaming sets the Miami Mayhem™ max win at a solid 15,000x the bet.

When playing the Miami Mayhem™ demo slot, my best streak came by landing Crew Reels in the We Split Bonus round. You can try out the free version in our catalogue of free online slots.

Miami Mayhem™ Theme—Stay Safe and Avoid the Street Mayhem

miami mayhem slot base game

As the name already suggests, there is nothing like peace in the Miami Mayhem™ slot game. Picture an urban street gang running every corner of the city, intimidating residents and clashing with rival crews. It feels like one of those new online slots inspired by Grand Theft Auto.

The grid is set on a street with Diego el Fuego, one of the gang members, armed with a baseball bat. He is replaced by Ghosting Gordo, another jacked criminal, and Roxie Rizz in the bonus rounds. Although the designs look clean and sharp, I wasn’t entirely thrilled by them.

The tense soundtrack matches the crime theme, and it ramps up in the bonus round. However, the occasional voiceover didn’t do it for me.

See what the paytable looks like:

Miami Mayhem™ Mobile Slot

miami mayhem mobile slot

I didn’t notice a drop in performance when trying out the Miami Mayhem™ mobile slot. The visuals stay sharp and vibrant, and the controls are responsive on smaller screens.

Between portrait and landscape, I found the latter holds up better at mobile casinos. The layout feels a bit too tight in portrait mode.

Miami Mayhem™ Bonus Features

The gameplay centres on landing an expanding symbol, which can sometimes display a multiplier. Also, like we’ve seen in the provider’s best slots online, this game comes with multiple bonus rounds and a bonus buy feature.

Expanding Crew Reel

When a Crew symbol lands, it will transform into an expanding symbol, Crew Reel, if there is a possibility that it takes part in a winning combination. The expanded symbol covers the entire grid, displaying a crew member.

The expanded symbol counts as a Wild, helping to complete winning combinations. It can also reveal a multiplier value between 2x and 100x, which applies to the winnings the Crew Reel is part of.

If multiple Crew Reels with multipliers take part in a win, the multiplier values are first summed up before being applied to the payout.

Missions

A Wanted symbol, represented by a Star with sirens, activates a Mission sequence when it lands on the reels. When triggered, it activates a Wanted Level bar, assigns a Mission Target, and awards 3 respins.

A random high-paying symbol is selected as the target at the beginning of a mission. To complete the mission, land a winning combination that includes the target symbol within the awarded respins.

Completing a mission resets the spin counter and increases the Wanted Level by at least 1, and also unlocks another mission. The progress continues until the 5th Wanted Level, where the progress becomes static.

In addition, the minimum multiplier value on the Crew Reel increases progressively with the Wanted Level.

Wanted Level Minimum Multiplier Value
Level 1 2x
Level 2 5x
Level 3 10x
Level 4 15x
Level 5 25x

The Hit Bonus Game

miami mayhem slot free spins

Landing 3 Scatters in the base game triggers 10 free spins. You have better chances of landing the crew symbols in the bonus round. A mission is triggered at the start of the round, and the Wanted Levels will be progressive, so respins aren’t awarded.

Retrigger 2 and 4 free spins by landing 2 and 3 Scatters, respectively.

We Split Bonus Game

miami mayhem slot we split bonus game

Trigger this bonus game by landing 4 Scatter symbols in the base game. The round starts with 10 free spins, and it maintains the mechanics of the Hit Bonus, but here, each reel has a Mayhem Bar.

Whenever a Crew Reel appears, the respective Mayhem Bar is filled, and a Crew Spin is awarded after the last free spin. In this spin, collected Crew Reels appear with multiplier values.

Like the Hit Bonus, you can retrigger 2 and 4 free spins by landing 2 and 3 Scatters, respectively.

Hidden Epic Bonus

The bonus round is triggered by landing 5 Scatter symbols, awarding 10 free spins. It maintains the mechanics of the We Split Bonus, and it also guarantees that at least a crew symbol will appear on every free spin.

Even more, the round is played on Wanted Level 5, so Missions cannot be triggered. You have better chances of landing Crew Reels with higher multiplier values. Unlike the other bonus games, you can’t retrigger additional spins here.

Bonus Buy (Unavailable in the UK)

Activate the Bonus Buy option to move into the bonus round directly from the base game. Here are the available options:

  • BonusHunt FeatureSpins™ (5x the bet): 5x more likely to trigger a bonus game.
  • Beach Please FeatureSpins™ (50x the bet): Guarantees at least 2 Crew Reels form.
  • Mayhem Mode FeatureSpins™ (50x the bet): Triggers the Missions feature.
  • The Hit (100x the bet): Triggers the Hit Bonus game.
  • We Split (300x the bet): Triggers the We Split Bonus game.

Miami Mayhem™ Verdict: Great Gameplay with Exciting Features

4.3/5
Based on our expert’s review. Reviewed by
Miami Mayhem™ Slot

If you’re after an exciting but volatile gameplay with multiple bonus rounds and vibrant scenes, the Miami Mayhem™ slot game might be an ideal choice.

Pros
  • Loaded with bonus features
  • Offers a 15,000x max win
  • Delivers expanding reels with up to 100x multiplier
  • Visuals are eye-catching
  • Gameplay is exciting
Cons
  • Just 14 paylines

Can Hacksaw Gaming ever get it wrong? Well, not with the Miami Mayhem™ slot. Although I have seen more fascinating visuals from the provider, this doesn’t perform badly. It’s exactly what you’d expect from a Grand Theft Auto title—vibrant, bold and unrepentantly violent.

At this rate, it’s fair to say that the studio has made the expanding reel wild multiplier mechanic its own. Just like what we saw in Aiko and the Wind Spirit™ and Fighter Pit™, the multiplier values cap at 100x and play a big role in delivering the top reward.

The Mission feature stood out to me during my playtest. Every respin builds anticipation of forming a win with the target symbol, which unlocks a new mission. It’s not something I have come across often.

For more slots inspired by gang violence, try out Dead Rider’s Trail by Relax Gaming. It features a group of bikers on a rampage, offering a top win of 50,000x the bet.

Additionally, for those who prefer some heroic battles, I recommend playing Hero’s Quest by Bally Wulff.
