Miami Mayhem is a video slot developed by Hacksaw Gaming, featuring a distinctive visual presentation consistent with the studio’s established design and gameplay approach. It incorporates several familiar mechanics found in other Hacksaw titles, offering a recognisable yet well-executed setup.
The game is played on a 5×4 reel layout with 14 fixed paylines. It supports bet amounts ranging from €0.10 to €100 and features high volatility gameplay with a return-to-player (RTP) rate of 96.35%. The maximum win available reaches up to 15,000x the stake.

This game draws clear inspiration from the Grand Theft Auto series, particularly in its visual style, narrative elements, and overall atmosphere. The characters, symbols, and in-game features reflect familiar themes often associated with the cult game’s brand. However, despite its influence, the slot manages to avoid feeling like a copy and establishes its own distinct identity.
The storyline follows a crew of five misfit characters called Ghosting Gordo, Roxie Rizz, Vinny the Vice, Lola la Reina, and Diego el Fuego. They’ve teamed up for the ultimate heist in a city where danger is always close. Between shady deals, crooked authorities, and constant threats, they’ll need to keep their heads down and stay ahead if they want to pull it off.

This feature appears frequently across the studio’s slots and plays a central role in Miami Mayhem. It involves Crew symbols, which act as special Wilds. When one of these symbols lands and can contribute to a win, it expands to cover the entire reel. The expanded symbol will display one of the five outlaws, depending on which reel it lands on:
Once expanded, each Crew Reel functions as a Wild across all its positions. In addition, it may randomly reveal a multiplier value ranging from 2x to 100x. This multiplier applies to the full reel and all wins it is a part of. If multiple Crew Reels appear in a single win, their multipliers are added from left to right before being applied to the payout.
Note: Only one Crew symbol can appear on a reel at a time, and regular Wild symbols are also present in the game.

Missions activate when a Wanted symbol lands on the grid. This symbol can be identified by a badge design featuring a star and police sirens.
Triggering a Mission activates the Wanted Level Bar above the grid. It then selects a Mission Target and awards three respins. The bonus begins at Wanted Level 0 and can increase up to Level 5.
At the start of each Mission, one high-paying symbol is randomly chosen as the Mission Target. To progress, a winning combination must include this target symbol. Completing a Mission refills the respins to three, triggers a new target, and increases the Wanted Level by at least one step.
If the Wanted Level reaches 5, it stays locked at that level. Additional Missions can still be triggered, and the round continues until a Mission fails (i.e., all respins are used without a qualifying win).
As the Wanted Level increases, the minimum multiplier value on expanded Crew Reels rises:

This bonus round activates when three Scatter symbols land, awarding 10 free spins. The core mechanics from the base game remain active, though Crew symbols are more likely to appear during this feature.
The round also starts with a Mission, but without respins. Instead, the Mission feature plays out for the duration of the bonus. Extra Scatter symbols during the round can extend the feature as so:

This bonus activates when four Scatter symbols land, awarding 10 free spins. It shares mechanics with the previous round but adds the Mayhem Bar, which sits beneath the grid.
The Mayhem Bar has one compartment for each reel. When a win occurs involving an expanded Crew Reel, that reel is collected and stored beneath the corresponding reel. After the last free spin, the Mayhem Bar activates one Crew Spin, during which all stored Crew Reels return to their positions and apply their multipliers.
Only one Crew Reel can be stored per reel, with a maximum of five stored at once. If no Crew Reels are collected during the round, the Mayhem Bar does not trigger.
Additional Scatters during this feature also extend the round as follows:
This is triggered by landing 5 Scatters and triggers a free spins round with 10 free spins. It generally functions like the rest of the bonus games, but it guarantees that one Crew Wild symbol will land on every spin and locks the Wanted Level at 5 throughout the round, maximising Crew Reel multipliers.

The slot features several Bonus Buy options that provide instant access to specific game modes or enhanced base game spins. Each option has a set cost relative to the base bet and comes with its own volatility level and return-to-player (RTP) rate.
Miami Mayhem pulls off a solid mix of theme, features, and high-stakes potential without losing its own identity. The style influence is clear but never overbearing, and the slot backs it up with sharp mechanics. Its expanding Crew Wild Reels add momentum to the base game, while the Mission system and tiered bonus rounds keep the structure engaging overall.
There’s a clear effort to tie the gameplay to its narrative, and it mostly works. Taken as a whole, it’s one of Hacksaw’s more cohesive and confident releases, packed with strong mechanics, smart design choices, and memorable in all the right ways.
