King Colossus Demo Mode

Quickspin made King Colossus not about intrigue, but about pure luxury: gold along the edges, gemstones in the centre and one very pleased monarch. In 2014, the game received a striking trick — the king expands into a 3x3 symbol in the bonus, while lion wilds wink from the sides. The demo is available on this page, and other Quickspin games can be found in the Legalbet online slots section.

King Colossus: Design and Theme

🖼️ Graphics

The background shows desert tents and chests of gold, creating the feeling of a temporary palace set among the sands. The screen is framed with heavy gilding, while the reels shine with cold blue tones so that the gemstones burst with brightness. In the bonus scene, we are taken to green halls: columns, carpets, glitter. When the king expands, the interface pulls the middle reels together into a single shield — the image becomes monumental.

🎶 Sound

The melody is majestic, as if in a divine temple. Against it, the spins sound like sharp clicks, deliberately breaking the harmony — it feels like the mechanical ticking of a treasure vault. The scatter stands out with a separate chime: a short, clear signal before the scene shifts. In the bonus round, the orchestral backing becomes richer and hits land with sharp accents, emphasising the king symbol’s growth.

Special Symbols

To quickly understand how to play King Colossus, keep your focus on two things: the expanding King in the bonus and the lion wilds that help complete lines.

  • Wild (lion): substitutes all symbols except the scatter and the +1 Spin token. In the base game, it also has its own payouts: 2 — x0.125, 3 — x0.75, 4 — x2.5, 5 — x12.5.
  • Bonus Wild (lion with a red frame): appears only during free spins on random positions of reels 1 and 5; acts as a wild but has no payouts of its own.
  • Scatter (BONUS portal): required to trigger the free spins.
  • +1 Spin Token: awards an additional spin during the bonus game.

Bonus Game

All the magic happens in the free spins:

  • 3 scatters — 5 free spins.
  • The King symbol can appear on the middle reels and transforms into a 3x3 block, merging reels 2–4.
  • On each spin, one or several Bonus Wilds may appear on reel 1 and occasionally on reel 5, staying for the duration of that spin.
  • A falling “+1 Spin” token adds additional spins (a short-form retrigger).

RTP, Volatility, Max Win

RTP — 96.57%. Volatility is medium. The maximum win is capped at x500 of the stake.

Our Verdict

King Colossus plays with a certain charm: the base game is calm and steady, while the bonus is built from clear components — a huge 3x3 symbol in the centre, lion wilds on the edges, and short “+1 Spin” top-ups. The slot feels like old-school Quickspin: a little measured, but with lively spikes when the grid locks into place.

If you want something similar in spirit but on a larger scale, try Gates of Olympus 1000. And for a complete mood change, Babushkas offers symbol upgrades and dancing bears.
