Interactive mechanics that require player decisions
-
Cinematic elements that tie into the slot’s story

Game-changing modifiers like reel-swapping, symbol upgrades, or persistent multipliers

Bonus games within the game that offer new win paths or experiences
These features make the game feel more like an adventure than a simple gamble, keeping players immersed and entertained.
