Review

This slot has brought us a couple of interesting online slots, but the overall quality of their releases tends to be somewhat unreliable. That’s where our detailed slot reviews can come in handy, and we’ll take a look at the game in this one. It’s a 5x4 slot with 40 paylines, and it has quite a few nice tricks up its sleeves!

The setting will take you to the laboratory of a certain crazy scientist, and the lab is naturally full of crazy gadgets. It’s a nice theme that also manages to be fairly original, but, unfortunately, the level of polish isn’t exactly great, and some of the game’s visual details look a bit off. It’s not a disaster by any stretch of the imagination, but things could’ve certainly been a bit better.

The mathematical model combines a medium volatility level with a solid hit frequency of 26.94%. Its jackpot is then worth 6,255x your bet, and it’s possible to dive into the game for many different bet levels between £0.40 and £120 per spin. As most slots, even this one comes with RTP ranges, and the available RTP values are 88.13%, 94.07%, and 95.52%. In other words, it’s nothing to write home about.

Slot Features

The paytable is dynamic, which means that you can always easily check how much you stand to win for each of the available combinations. There are then as many as 11 pay symbols, and the set is divided into 5 low-paying symbols and 6 high-paying symbols. For the former, there are brightly-colored card ranks from Nines to Aces, while the latter feature vials, notepads, microscopes, flasks, cash containers, and even the crazy professor himself.

Aside from pay symbols, the game’s reels also offer three special symbols. Specifically, there are Wilds, Free Games symbols, and Electric Scatters. Wilds can substitute for any of the pay symbols, and they also come with their own payout values. Free Games symbols and Electric Scatters, meanwhile, interact with the slot’s bonus features.

Moving on to the slot’s gameplay, there’s the Mystery Replacement feature, which changes some of the symbols on the game’s reels into matching ones at the start of each spin. That means that you should – in theory – be more likely to win, but this feature is naturally already factored into the game’s hit frequency.

Next, there’s the Replicating Reels feature, which you can trigger either at random or by landing 2 Electric Scatters in one go. Then, you’ll get a spin with special Replicating Reels that are synchronized, improving your chances to win by a big margin.

To trigger the Free Spins feature, you have to land full stacks of Free Games symbols on 2 or more reels. Then, you’ll get 7 free spins with the Replicating Reels feature in play at all times. By landing full stacks of Free Games symbols, you can also shutter reels and make them Replicating for the entire feature, and there’s also the special High Voltage Mode that can net you more Free Games symbols and help you out that way.

Last but not least, there’s also the Buy a Bonus option, which will take you right to the Free Spins feature for 120x your bet.

Review Summary

All in all, this online slot is a rather mixed package. On one hand, we like its theme and bonus features. On the other hand, it’s hard to enjoy many aspects of its presentation, and its math model leaves much to be desired as well. It’s fine enough, and clearly have a lot of potential, but it’s not as polished as it could’ve been.
