Miami Mayhem

Reviewed by Paul Clare Last updated:

Hacksaw takes us back to 80s Miami when gangs ran the streets with baseball bats and wore fabulous clothes. Big gold chains are included as standard, as are large, hooped earrings. Three free spins bonuses and a string of base game modifiers could see you walking off with a 15,000x top payout in Miami Mayhem this summer.

Miami Mayhem Review

I'm not sure what has rattled this chap in the purple vest, but it looks like he's ready to start something nasty and then possibly take you to a disco afterwards. There’s a strange blend of crime and camp going on and I'm intrigued to see where this goes!

Gameplay & Features

The royal symbol wins will barely return your base bet and most of the paying picture symbols will require you to get at least four matching symbols to start seeing your balance move towards the positive side. 

The highest payers can get you up to 10x but you're going to need a group of five of these. Crew symbols and wild symbols will get you the same results as the highest-paying symbol. Wild symbols substitute for other regular payers and the crew symbols trigger a mini feature. They expand into a reel which is now wild and can help substitute for other regular payers. It may also get multipliers added between 2x and 100x when this happens. 

Missions trigger when wanted symbols land and activate the wanted level bar. You get three respins and you need to hope that you land the specific symbol that is designated. If you complete this mission, you get a guaranteed 2x multiplier with any expanded wild and then this continues until they get to the final level with a 25x multiplier. 

Bonus games 

The 1st of the three bonus games comes when you land three scatter symbols during the base game. You now have a better chance of triggering the crew symbols and you'll get 10 free spins. The bonus plays out in much the same way as the base game but the wanted levels will be progressive and one mission triggers at the start of the bonus. You can pick up extra spins as you play. 

Four bonus scatter symbols also trigger 10 free spins and everything you received with the standard bonus game now continues. After your last spin, the Mayhem Bar activates and the multiplier value will assist your payouts. 

Five scatter symbols force the hidden bonus game to appear where you'll get 10 free spins and everything that you've seen before. You're guaranteed to get at least one crew symbol with every spin and the wanted level is always at 5. As a little extra bonus, you’ve got an increased chance of landing an expanded crew reel with higher multipliers. 

You can pay 3x to make each spin five times more likely to trigger a bonus game and 50x will get you a spin with a guaranteed pair of expanding crew reels. 50x also brings you a wanted symbol and triggers a mission. Outside the UK, players have the option of paying 100x or 300x to see the basic and mid-range free spins bonuses, respectively.

Miami Mayhem - Expanding Reels

Expanding Reels

Crew symbols may land and expand if they can form part of a win. They cover the entire reel and will show one of the five crew members. These guys can act as simple wild as they substitute for other regular payers or they may offer multipliers worth between 2x and 100x. Multipliers can combine.

Miami Mayhem - Missions

Missions

Trigger missions when wanted symbols land and activate the wanted level bar. You get three respins and if you hit the target symbol during that time, you start a new mission. The wanted levels increase as you move through the missions and the result is that the minimum multiplier applied to the crew reels will start to increase.

Miami Mayhem - Free Spins

Free Spins

Three scatter symbols will produce 10 free spins and you'll see much of the same base game fun carry on, but you now have a better chance of landing the crew symbols. The wanted levels are progressive, so they won't reset and you get one mission triggered at the beginning of the game. Four scatter symbols offers a very similar bonus game but you can now build up a mayhem bar which triggers a crew spin. The final bonus requires five scatter symbols and one crew symbol will always land with each spin. The wanted level is always at 5.

Win Potential

You've got some medium-high volatility to contend with throughout this game but there is a max win of 15,000x to look forward to. I didn't get much love from the base game, even though the missions were able to offer the occasional multiplier. The rewards get bigger and better as you progress through the range of free spins bonuses and for players outside the UK, it's going to be very tempting to head straight there.

Design

Miami Mayhem has quite a camp feel, even though it's supposed to be based on some rough crime gang! Everything is blended with an 80s shock of purple and palm trees that depict the era perfectly along the Miami coastline. The soundtrack wouldn't be out of place in an episode of Stranger Things and you can grab all of the action on your mobile phone if you prefer to play while on the move.

Our Verdict

The method of reaching the various modifiers during this game is quite unique and even though it seems a little long-winded, it can produce some pretty decent results from time to time. The bonus games are where the cash is at and you get a better glimpse of how powerful these modifiers can really be when you get there. Miami Mayhem might just offer enough of a twist and turn here and there to draw your attention towards it.
