Troll K.O. Slot Review

How to play

This video slot has an unusual set up to accommodate all the action possible. There are six reels, four rows, and 50 fixed paylines. The betting range for this game is on the low side, which is great for casual gamblers looking and newbies alike. The minimum stake per spin is €0.50, for a €0.01 line bet. The maximum stake per spin is €25.00, for a €0.50 line bet. Autoplay is available from 10 to 50 spins with customizable win/loss settings, but there is no option for Turbospin.

The sound and music can be controlled separately or muted, and you can even see your game history. The Knockout stone pillar is set to the right of the reels. There are 10 explosives that you can choose to detonate, which will eliminate certain symbols. This will trigger a singular cascading reel. We’ll cover the when and why later. For now, just keep in mind that it will take five paid spins to recharge one explosive.

Symbols and payouts

There are a lot of characters to keep track of in this game, because it differs between the base reels and the free spin reels. There are three tiers of prizes: low, mid, and high. The low-paying symbols are used for both reel sets, but the mid and high will swap out. Those low paying symbols are a pile of bronze coins, a silver ingot, a gold ingot, green crystals, and diamonds. The base game mid-values are green, grey, or yellow goblins. The high tier has green, orange, or red trolls.

In the free spins, the middle tier has a chicken, a blue goblin, and a horse. The high-values are a woman, an old man, and a young man. The high-paying symbols in both reels – the red troll and the young man – offer the same prize. They award a 2,000x the line bet when you land six on a payline. This is the highest payline prize in the game. There are also two special symbols. The wild will substitute for all symbols listed above. Finally, there are loot boxes that only appear in the base game.

Best Troll K.O. bonus feature

Loot boxes are the best Troll K.O. bonus feature, without a doubt. Loot boxes hold various prizes – free spins, total bet multipliers, or both. You need to line up three loot boxes horizontally in order to collect your prize. Of course, this can be more difficult than it sounds. Sometimes loot boxes will be hiding above the reels by two or three spaces, and you’ll need to look for visual clues to identify them. You’ll be able to use the Knockout feature to remove symbols that are in your way. It’s only available to knockout symbols that have a loot box on the same reel above them. Destroying that icon must help move the loot box into position, or it won’t activate.

The multiplier and free spin awards will depend on the number of triggering loot boxes you line up. Three boxes will award up to 2.5x the total bet and/or 15 spins. Four boxes award up to 5x and/or 30 spins. Five awards up to 8x and/or 60 free spins. And six boxes on a row awards up to 10x your total bet and/or 80 free spins. What happens if you realize you missed a great match? The game takes that into account and weights your next loot box prize into your favor via the skill balance pot.

RTP & volatility

The Troll K.O. RTP is set by the casino operator but can vary between 93-97%. An RTP of 93% is notably below average for a video slot game, since most of them run around 95% RTP. However, the dynamic bonus features might be enough to entice hesitant players. The slot demonstrates medium volatility. Gamblers can expect a steady mix of large and small wins during play.
