KA Gaming presents two mechanic families as proprietary concepts: Lock 2 Spin™ and Fusion Reels™. The official site lists them among distinctive ways to play alongside paylines, ways and clusters. Multiple themed titles can use the same family, so full game names matter: a Lock 2 Spin or Fusion Reels edition may be a separate release rather than a switch inside a base slot.
Lock 2 Spin™ broadly follows a respin model in which some symbols stay locked while the feature continues through repeated spins. Exact triggers, respin counts and reset rules vary by game. Black Swan Lock 2 Spin is a representative example in the current catalogue.
Fusion Reels™ centres on combining or expanding reel positions. Depending on the title, the feature can change symbol size or reshape the structure of winning combinations. Museum of Fantasy is a useful example of the family, and the catalogue also includes releases with Fusion Reels directly in the title.
Beyond those families, KA Gaming slots use Free Spins, Bonus Games, Buy Features, wheel bonuses, jackpots, bonus reels and selected skill-like bonus features. Current filters on the official site show hundreds of releases with Free Spins and Free Rounds, dozens with Bonus Games and smaller groups for Buy Feature, Wheel Bonus, Jackpot and Skill Bonus. A category label does not mean the same feature works identically across every game.
Fish/shooting games use a different loop. Their key elements are a multiplayer scene, weapons, targets with different values and boss fish rather than a standard reel grid. Comparing a fish game with a slot only by theme or maximum multiplier can therefore be misleading because the underlying play cycles are different.
