Theme & Visuals

The theme used for Dr Zappo reminds me of one of those futuristic cartoons. A bit of Futurama, maybe?

Dr Zappo and his lab monkey stand next to the game area and observe the gameplay but don’t interfere, as characters sometimes do in other Hacksaw Gaming slots.

Slot Features & Bonus Rounds

Eyeballs! You want to see those eyeballs to benefit from spreading wilds and multipliers.

Wild Eyeballs

The eyeball can land on the 4^th reel in the base game and will shoot wilds in 1 of 3 directions. The wilds can also get an additive multiplier of 2x to 200x.

If an eyeball hits an existing wild symbol, it will gain a multiplier.

Energy Fields

Energy fields are located on the left, top and right edges of the grid. If an eyeball stream hits an energy field, it bounces off and continues in another direction at the same angle.  

Free Spins

Landing 3 or more FS Scatters triggers 10 free spins.

Landing an additional 2 or 3 scatters during the bonus game adds another 2 or 4 free spins to your total.

• 3 Scatters: Increased chance of landing eyeball symbols.
• 4 Scatters: Eye symbols will shoot in two directions.
• 5 Scatters: Guaranteed to land an eyeball symbol on each spin.

Symbols & Payouts

Dr Zappo features 10 regular pay symbols and a wild.

• Low-paying symbols can pay up to 1x the bet for 5 matching royal symbols.    
• High-paying symbols can pay up to 5x the bet for 5 Dr Zappo symbols.    
• The Wilds also pay 5x the bet for 5 of them on a payline.

CasinoWizard’s verdict: Dr Zappo really comes to life in the free spins (7 out of 10)

The initial enthusiasm starts to fade away quite quickly if you don’t start landing those eye symbols anytime soon, as there isn’t much happening apart from those in the base game. Regular, often smaller wins stop feeling exciting after a while.

However, when the eye symbol decides to make an entrance, the game suddenly elevates. This doesn’t happen too much in the base game, so your best chances to experience what this game really has to offer are to reach the free spins by landing 3 or more scatters.

The three scatter free spins increase your chances of landing eye symbols, while the 4 scatter free spins make sure that the eyeballs shoot wilds in two different directions, and this can make all the difference.

The 5 scatter free spins will naturally be difficult to trigger, but these free spins guarantee an eyeball symbol to land on every spin.

Hacksaw Gaming has used similar features in the past, for example, in Fire My Laser (excellent game), where the lasers shot in different directions.

Dr Zappo isn’t as entertaining as that slot, but it’s still good. A slightly more entertaining base game would have pushed the rating up a notch, but experiencing the free spins, where you land plenty of eyeballs and see the wilds spreading across the game area, and ideally with some multipliers added in there, is good fun.

If you enjoy Dr Zappo and want an even quirkier theme, try Jaws of Justice, which Dr Zappo is a reskin of.

Final verdict: 7 out of 10.

Dr Zappo is officially released on September 29, 2026.
