A Bonus Game is a special reward stage that activates when a specific condition is met (usually the appearance of 3 or more 'Bonus' symbols), transitioning from the spinning reels to a completely new and separate game screen. This is different from features like free spins, where new rules are added to the existing reels. The core of a bonus game is to provide a new experience, as if you are enjoying a 'mini-game within the game', completely breaking away from the basic slot gameplay.

Reel Expansion is a feature where the physical size of the game grid (reels or rows) actually gets bigger, typically upon entering a bonus round like free spins. This goes beyond simply adding a multiplier; it aims to expand the 'board' of the game itself, providing players with a wider field of opportunity and fundamentally increasing the number of winning ways.
