Troll KO | Slot Demo & Review ➤ Green Jade Games

Troll KO slot review

Following the success of Hammer of Fortune, Green Jade Games comes up with a follow-up, once again taking players on an exciting reel adventure through the fantasy realm. Featuring trademarked Knockout and Skill Balance Pot mechanics, Troll KO is yet another slot to complement the developers' KO slot series, which appears to be pretty successful. Thanks to Green Jade's proprietary Skill Balance Pot, casino operators can offer much more rewarding games without damaging the house edge.

Our KO suite of games is proving to be super popular with players especially in Germany, Netherlands, and the UK. Each features our patented Skill Balance Pot, whereby if there is a win to be had and the player doesn’t take it, it goes back into the game meaning more riches on offer for the next intrepid player. This is yet another example of how Green Jade aims to give more than just the standard slot game, adding advanced interaction and handing more control to the player. Skilled competitors will be able to harvest rewards others may miss, giving a higher RTP profit and a chance to top the leader board for even more big prizes.

Troll KO - Slot Outlook

Once released, Hammer of Fortune became a huge hit since it offered a unique casino gaming for it boasted a plot, different chapters, vibrant characters, and immersive dialogues. Troll KO, however, offers a more traditional experience. Loading the game will take players to a massive semi-transparent 6x4 grid with 50 ways to play, which dominates the view, while the backdrop showcases a beautiful meadow amidst dense woods. A piece of suspenseful epic music plays whilst you spin the reels to add a final touch to the general ambiance and set players in the right mood for smashing trolls.

Troll KO Reel Screen

Playable on any device, Troll KO offers a betting range from 0.5$ to 25$ per spin. It comes with medium volatility and ranging RTP values from 93% to 97%, so keep that in mind and be sure to check the stats before depositing. Meanwhile, the maximum potential is 2,000x of the bet. Even though it's not the biggest payout potential we've seen so far, it could be justified by the generous math model and the Skill Balance Pot.

The symbol collection includes 11 regular symbols, split into 3 categories. On the lower side, we see a bunch of coins, silver and gold ingots, and emeralds and diamonds, while mid and high pays involve various trolls. During the bonus game though the more valuable symbols transform into more recognizable icons, namely Brin, Papa, and other characters taken from the Hammer of Fortune slot.

Scoring wins requires matching at least 3 symbols on a line, while full combos are achieved by landing 6 instances of the same symbol on a single payline. The payouts are moderate, with low-paying symbols awarding from 3x to 8x of the bet for 6-of-a-kind combos, and mids and high from 10 to 40 times the stake.

Troll KO - Bonus Features

Like other games in the KO slot series, Troll KO is light on features and relies heavily on the Knockout mechanic. Unlike regular slots, here the bonus game is activated when 3 or more Loot Chests align horizontally on adjacent reels anywhere on the grid. It might seem quite a challenging task, though, the Knockout feature comes to the rescue.

This allows you to remove any symbol from the grid to line up the chest symbols. Whenever the symbol is removed, all symbols above it tumble down to fill empty spaces. You can have up to 10 charges, and it takes 5 spins to accumulate one charge. Moreover, with the help of the KO feature, you can get extra bonus symbols in addition to those already in view. If there's an opportunity to land an extra Loot Chest, a hint appears above the respective reel, displaying a chest. However, it can take up to 3 Knockouts to drop the hidden chest, so use them wisely.

Once 3 or more chests are aligned, players unlock them to reveal either a cash prize, or Free Spins, or both. The more bonus symbols you manage to land, the higher will be the prize:

• 3 Loot Chests - 2x - 2.5x cash prize / 10-15 Free Spins
• 4 Loot Chests - 4x - 5x cash prize / 20-30 Free Spins
• 5 Loot Chests - 6x - 8x cash prize / 40-60 Free Spins
• 6 Loot Chests - 10x cash prize / 70-80 Free Spins

Troll KO - Slot Verdict

While Hammer of Fortune stood out from the crowd with its unique gameplay and narrative story, Troll KO sticks to a different concept, offering a standard slot gaming experience. It feels like a common slot with not so many things to do and the only distinctive feature here is the Knockout mechanic. It's still capable of delivering tons of fun and tasty payouts, though, it won't surely manage to surpass its older sibling and is likely to be overshadowed by it as just a cut-down version.
