Machine Gun Nellie - Review, Demo Play, Payout, Free Spins & Bonuses

Machine Gun Nellie Slot Review

Not all Skywind slots feature 7 reels or replace paylines with cluster pays. Most slots with a bank robbery theme don’t have an elephant main character. Welcome to our Machine Gun Nellie slot review, where we explain what makes this game distinct, including its various modifiers, multipliers, and free spins bonus. We’ll also touch on responsible gambling, including self-exclusion to control your play.

The Golden Age of Bank Robbery

During the Prohibition and Great Depression periods, organized crime began to rise, with infamous criminals like Bonnie and Clyde, Frank Dillinger, and Baby Face Nelson pulling off daring bank heists. This was the golden age of bank robbery, providing the perfect inspiration for a video slot.

Nellie the Elephant

While the setting features familiar elements of bank robberies—bank vaults, getaway cars, and machine guns—there’s one thing that sets this slot apart: an elephant. Machine Gun Nellie (a pun on the infamous gangster Machine Gun Kelly) is an elephant dressed and armed like a 1930s bank robber. She’s not a comic character but a serious criminal in the game.

Machine Gun Nellie RTP and Variance

The Machine Gun Nellie slot offers an RTP of 96.5%, although some casinos may set it lower. The variance is medium to high (4/5).

How to Win at Machine Gun Nellie

Unlike most slots that use fixed paylines, Machine Gun Nellie uses cluster pays. To win, you need to form a cluster of at least five matching symbols anywhere on the 7x7 grid, either horizontally or vertically. Your main objective is to trigger the Machine Gun Nellie bonus features.

Top Wins

• The payout potential is highest when a cluster has at least 15 matching symbols.


• Diamonds and clubs can pay up to x10 your stake.


• The getaway car offers the top win of x100.


• There are 8 regular paying symbols. The scatter symbol pays a flat rate of x2, while wilds don’t pay. Wilds and scatters help trigger bonuses.


• The max win available is x5000.

Machine Gun Nellie Bonuses

Machine Gun Nellie features cascading symbols, multiplier hotspots, and a bank vault bonus round that adds modifiers to enhance your gameplay.

Cascading Symbols

In Machine Gun Nellie, cascading symbols work as usual by removing winning symbols and allowing new ones to replace them. What makes this unique is that when symbols are removed from the same position twice in a row, it creates a multiplier hotspot. This multiplier starts at x2 and grows every time another winning symbol is removed, up to a maximum of x128. Your total win is then calculated from all clusters and multipliers.

Free Spins

Free spins are triggered by scatter symbols:

• 4 scatters: 10 free spins


• 5 scatters: 12 free spins


• 6 scatters: 14 free spins


• 7 scatters: 16 free spins

For every additional scatter symbol during free spins, you’ll earn 5 extra free games. During the free spins, any multiplier hotspot that is triggered won’t reset when the cascading sequence finishes and will persist until the feature ends.

Bank Vault

If a wild symbol is part of a winning cluster, it triggers a bonus wheel shaped like a bank vault door, offering several potential prizes:

• Double Whammy: Doubles your triggering win.


• Global Upgrade: Doubles the value of all multiplier hotspots.


• Win-ferno: Adds 3-5 fire wilds to the gaps left by winning clusters.


• Sniper Wilds: Adds 2-5 wilds to your next cascade.


• Shotgun Upgrade: Selects a 2x2 or 3x3 area, increases hotspot values, and turns regular positions into hotspots with win multipliers between x2 and x5.

Note that fire wilds cannot trigger additional bank vaults.
