Arena of Iron

Arena of Iron: Slot Overview

With the way AI seems to be advancing into all spheres of life, maybe one day in the not-too-distant future, AI-powered robots will be doing just about everything for us. Manufacturing, making our art, making war, while we, what? Watch TV shows written by machines, as we ease deeper into the couch groove, while robot butlers ensure we are topped up with nutrients and change the channels for us? With this in mind, we step into the world of Arena of Iron. Designed by Hacksaw partner Bullshark Games, this is a slot that offers a glimpse of the future where gladiatorial battles take place with the aid of cybernetic war machines, as humanity gets to watch the action unfold from the safety of the splash zone.

An arena is where the game is held, but this is no dusty ancient Roman amphitheatre drizzled in the blood of slain criminals and prisoners of war. This is the future, where metallic orbs float around menacingly, transports drift lazily across the sky, and a hulking gladiator dude, presumably a robot, gyrates next to the reels. Modern minds might look at what took place in the Roman arena with distaste, but it seems that in Bullshark Games' vision of the future, humanity still has a fondness for violence, and maybe if AI takes over all of our drudge tasks one day and we're gifted lives of absolute leisure, perhaps the digital neutering won't entirely erase our base animalistic urge to vanquish foes.

Technicals now, and the symbol arena is a 5-reel, 20-payline matrix, where players win by landing matching symbols left to right, from the leftmost reel. Available in two RTP configurations, 96.33% is the preferred return value, while Arena of Iron's volatility has been rated 4 out of 5. When picking a base stake, the options range from $/€0.10 up to $/€75 per spin.

Arena of Iron's pay symbols are 10-A royals, two circular objects, a chalice, a sword, and a helmet. Landing 5 matching royals awards 1x-1.5x the bet, or 2.5x-10x is awarded for landing 5 matching premium symbols. The wild symbol substitutes for all symbols on the paytable and can land in all game phases. A line of five wilds pays 20x the stake.

Arena of Iron: Slot Features

Features in this battle are a Multiplier Adder, a Robot Rumble bonus, The Deathmatch bonus, and feature buys.

Multiplier Adder

The Multiplier Adder symbol adds a random multiplier of x2 to x100 to positions in a specific direction. The possible directions are up, down, left, right, up and down, left and right, or all four directions. All multipliers added by the same Multiplier Adder have the same value, but several Multiplier Adders can have different values. If a symbol already has a multiplier value, the new value is added to it. After adding multipliers, the Multiplier Adder transforms into a random pay symbol. When a win includes more than one multiplier, the values are summed up. Multipliers reset with each new spin.

Robot Rumble

Landing 3 scatters triggers 10 free spins in the Robot Rumble round. During these free spins, the base game mechanics are kept, but any wild that lands becomes sticky until the end of the feature. Any multipliers added to a wild are progressive and do not reset between free spins. Each landed scatter awards +1 free spin before turning into a random pay symbol.

The Deathmatch

Hitting 4 scatters triggers 12 free spins in The Deathmatch round. This bonus keeps the mechanics of Robot Rumble plus at least one wild will land on the first spin.

Feature Buys

Arena of Iron comes with four feature buys. BonusHunt FeatureSpins cost 3x and make each spin 5 times more likely to trigger a bonus game. Quick Charge FeatureSpins cost 50x to guarantee at least 2 wilds and one Multiplier Adder land on the reels. The Robot Rumble bonus may be bought for 100x, or The Deathmatch costs 250x the stake.

Arena of Iron: Slot Verdict

Bullshark Games has designed a thought-provoking window into a mechanised future where a robotic form of blood sports is on the menu. The game manages to stand someway out not just for its futuristic skin and towering character, but for the way it converts its confrontational theme into volatile gameplay. It swaps the usual ancient history, duking it out in a Roman arena for cybernetic warfare, and the result is quite entertaining. It feels a little formulaic, as the gameplay structure boils down to triggering an interesting multiplier feature in the base game, enhancing it in the lower bonus round, then enhancing it slightly more for the second level bonus. However, layered over the skeleton of the structure are features which might be quite effective should they manage to bring their destructive powers to bear.

The Multiplier Adder is obviously one of the key components, and Bullshark have branched away from using a more straightforward common wild multiplier/wild reel multiplier feature. This method is able to spread multiplier values all over the reels, if you're lucky, though unlike the versatility of a wild multiplier, substituting anything, symbols with multipliers then need to be connected with other matching symbols to strike a win. The balance tips back towards wilds in free spins as Arena of Iron ups the ante by making wild symbols sticky and ensuring the multipliers that they collect are progressive throughout the bonus. It's a system with potential, and a win cap of 12,000x the bet, but linking all of the required parts together in order to produce a healthy return might be trickier than suspected.

In the end, Arena of Iron is a cleanly structured, volatile battle wrapped in a sleek sci-fi shell, where the progression from base game to bonus rounds provides ascending levels of punch. The link between sticky wilds and directional multiplier values adds a unique twist to standard multiplier fare, even if aligning all the necessary components for a major whack may require a fair amount of patience. It is hard to classify Arena of Iron as a great slot, but it's sturdy enough to deliver solid sticky wild/multiplier action.
