King Colossus is a medieval-themed video slot from Quickspin built around a giant, expanding King symbol. The 5-reel, 3-row, 40-payline game is set in a stone-walled royal court, and its core hook is simple: land the Free Spins feature and the King himself grows to fill a 3×3 block on the middle reels for oversized wins. Released in 2014, it was one of Quickspin’s earlier attempts at building a bonus round entirely around a single oversized symbol rather than cascades or extra wilds.

Free Spins are triggered from the base game and move play into the King’s Court, where every spin carries a Bonus Wild to help line up combinations. The signature mechanic is the high-paying King symbol growing to occupy a full 3×3 block across the middle reels whenever it lands, turning a single symbol into the backbone of several paylines at once. Because that expansion can happen on any Free Spins turn, a single trigger can chain several oversized hits back to back rather than relying on one big finish. Outside the feature, the base game plays as a straightforward 40-payline medieval slot with standard wilds and scatters building toward the next trigger, keeping the pace steady between bonus rounds.
