King Colossus Slot Overview

I have always liked how King Colossus from Quickspin throws you straight into a kingdom of gold. You start outside the dwarf king’s mountain court, following glowing piles of coins on a standard 5 reel, 3 row grid with 40 paylines. The set up is very straight forward, wealth themed and focused on lining up stacked symbols. Medium volatility and an RTP around 96.6 percent keep the maths fairly player friendly.

In King Colossus I feel the whole game really revolves around that audience with the King of Gold. Stacked King Colossus symbols and stacked Wild symbols dominate both the base game and bonus, capable of throwing out serious wins when they land together. Features stay tight and simple, with Wild Symbols, Massive Symbols and Free Spins carrying the game and giving a realistic shot at the stated max win of 500 times stake.

King Colossus Review

When I first loaded King Colossus, the look hit me straight away. The reels sit in a lavish chamber packed with crystals, gold and royal insignia, very much in line with its Arabian and emperor style theme. The soundtrack and effects back that up without getting in the way. It feels like a classic Quickspin video slot, with crisp symbols and a layout that makes the 40 lines easy to read at a glance.

From a player’s point of view King Colossus keeps things very straight forward, which I appreciate when I just want to relax and spin. There is no complex feature ladder or side game to track, so my focus stays on timing bets and watching for feature teases. That simplicity lets the stacked symbols and the bonus game do the heavy lifting, and most of the excitement comes from chasing that feature.

King Colossus features

The main attraction in King Colossus is the Free Spins feature. In the base game I am really just waiting for the chance to enter the King’s Court. Once the bonus triggers you start with 5 free spins, and there is a chance to re trigger extra spins one at a time. During this phase the King symbol grows, filling a 3 by 3 block on the centre reels for serious hit potential.

Free Spins in King Colossus come with Bonus Wild symbols on every spin, so I always feel the grid is primed for decent lines. Wilds combine with the enlarged King to land stacked wins across the 40 paylines, and this is where most of the game’s stated max win of 500 times stake lies. The feature trigger has an expected return of about 32 times bet, which matches how it feels in practice.

I treat King Colossus as a slot where the bonus round carries the balance of the value, so my betting reflects that. On medium stakes the swings feel fair for a medium volatility title, with the odd dry spell when the feature refuses to land. When Free Spins do appear, the stacked Wild symbols and massive Kings often throw in enough wins to keep me going for several more sessions.

King Colossus Attributes

Looking at the raw numbers, King Colossus is a 5 reel, 3 row video slot with 40 fixed betways and bets from 0.4 up to 120 per spin. Quickspin list the RTP around 96.6 percent with possible RTP ranges, and variance rated roughly 2.62 out of 5, so it sits in the medium bracket. The headline max win is 60000 credits, effectively 500 times max stake, delivered through those stacked symbols in the bonus.

King Colossus Paytable 1

The symbol set in King Colossus is built around wealth, with the King himself acting as the top paying icon. In the base game he appears as stacked King Colossus symbols, so full reel hits are common when he decides to show. During Free Spins that King swells into a massive 3 by 3 symbol across the middle, which tightens up the paytable and makes those premium lines hit much harder when the Wilds line up.

Wild symbols in King Colossus also come stacked, and during the bonus you get Bonus Wilds on every spin, so they appear far more often than in many older titles. That makes the overall symbol package feel very focused on coverage rather than single big icons. I find my better sessions usually come when stacked Wilds and the enlarged King overlap on the centre reels, showering 40 line wins across the screen.

Game Statistic. King Colossus by Quickspin

From a broader view King Colossus still shows up on a fair number of sites across different markets, helped by that solid medium volatility maths and clear feature set. Quickspin flag that the game uses RTP ranges, so I always check the current setting in the paytable before settling on a stake. For me it sits nicely as a go to gold themed option when I fancy stacked symbol action.
