Roll Zone

As thematic inspiration goes, the fallout from a nuclear war is probably not the most glamorous. Indeed, barrels of toxic waste, hazmat suits and lakes of putrid green liquid aren't the most spectacular sights to behold. Nevertheless, slot designer Felix Gaming has managed to make a slot game, Roll Zone, that is still entreating despite this Chernobyl-like atmosphere. Mechanically, this game is a four-reel and four-row slot with a cluster pays dynamic. This means players score wins by landing clusters of matching symbols together rather than aligning them on pay lines. The RTP for Roll Zone is 96.5%, and the volatility rating is medium. This game is available on mobile, tablet and desktop platforms.

Roll Zone Overview

The features of this game hinge chiefly on what is called a radiation zone bonus. This zone is a 2x2 area on the board that changes location with each new spin. Any icons within its perimeter mutate into four symbols, increasing the likelihood of scoring wins with these icons. The other feature of this game is the free spins round. This is triggered when players land a blue stalker icon in the radiation zone. For every one of these stalker icons that fall into this zone, the game will grant you more free spins. There is also a multiplier meter in both the free spins and base game. In the free spins, it does not reset after a losing spin. Furthermore, when multiple Green Stalkers enter the Radiation zone, you will increase the multiplier. All features will be explained in more detail later in the review.

Roll Zone Theme and Symbols

The theme for this game is a post-apocalyptic wasteland poisoned by a nuclear accident or weapon. High radioactive materials contaminate the setting, making for a bleak and unlovely atmosphere. Indeed there is a sense that this place is a hostile environment with dangerous radiation levels that have harmed living creatures, reduced vegetation, and damaged structures. This area looks uninhabitable and requires protective measures for those entering it. It is a harsh and toxic theme but novel in its design, it has to be said.

The background for this slot is the post-apocalyptic world that remains after some huge nuclear event, the details of which we are unsure of. The survivors of this event must fend for themselves in a harsh, dangerous world where resources are scarce and violence is common. The landscape is desolate and barren, dotted with the remnants of the old world, such as bridges and abandoned buildings. From the looks of the ice and snow, the event may have also caused what is known as a nuclear winter by blocking out the sun's rays with debris shot into the atmosphere. The playing board is a collection of valves and wheels like you might find in a nuclear power station.

The symbols are split into low-paying, high-paying and special symbols. The low-paying symbols are the J, Q, K and A in playing card royals. The more valuable icons, however, are the barrels of nuclear waste, the Geiger counter, the frozen door, the teddy, and the danger sign. The danger sign is the most valuable icon, worth 1,000x the stake for the top combination. The specials for this game are the characters in hazmat suits, one in green and the other in blue.

Roll Zone Features

As explained above, on each spin, the radiation zone stops on a certain area of the reels – this is the cordoned-off area delineated with yellow and black tape. All symbols found inside are split into four icons. This goes for both regulars and specials, with the only exception being the specials delivering modifiers. Players must land the green hazmat character inside the radiation zone to activate the multiplier. This will trigger a multiplier of between 1x and 9x to come into effect for all your wins. Landing additional green characters within this zone grow the active multiplier.

The final feature of this game is the free spins round. This is activated whenever the Blue Characters land in the Radiation zone. When it does, it grants between one and five free spins. Moreover, additional spins free of charge can be won similarly, and the Green Characters' multiplier stays persistent throughout the feature.

Conclusion

The theme here might get some getting used to, but the actual playing experience is pretty exciting, thanks mostly to the radiation zone and its associated bonus content. Regarding the winning potential, things look promising, with a high RTP, manageable volatility and a meaty top win.
