King Colossus Review

I've spun King Colossus by Quickspin for years, and it still plays clean and direct. The theme puts you before the King of Gold, with a 5x3 grid and 40 lines doing the work. Most of the value sits in the bonus game, yet stacked King Colossus symbols and stacked Wilds can throw out tidy base hits. RTP sits around 96.57% to 96.6%, with RTP ranges in some markets. Volatility is medium, so sessions ebb and flow without nasty shocks, provided you size stakes sensibly.

King Colossus features

Free Spins is the main feature in King Colossus. I trigger five spins to start, with +1 retriggers possible, and every spin uses a Bonus Wild to stitch wins together. The high-paying King grows into a 3x3 Massive Symbol on the middle reels during the feature, which is where the slot hits its stride. Quickspin list the feature trigger expected payout at 32x bet, and on my logs that figure feels about right over time, with the odd run spiking far higher.

In the base game, stacked Wilds and stacked King Colossus symbols can land screens that look and pay the part, keeping balance alive while you chase the Court. The rhythm suits medium volatility: stretches of small lines, then a feature that can open the taps when the Massive Symbol connects with Wilds. The stated max win is 500x the bet, which lines up with the design. It is not a marathon grinder; it wants tidy timing and a measured stake plan.

King Colossus Attributes

King Colossus runs on 5 reels and 3 rows with 40 paylines, a min bet of 0.4 and a max of 120. The RTP is listed around 96.6%, and the game can ship RTP ranges depending on the site. Volatility is medium. Symbols fit the gold-and-gems brief, with the King as the top payer in the base, and that same King expanding to 3x3 during Free Spins. Wilds substitute and arrive stacked, which pairs well with 40 lines when the middle reels light up.
