Selectable Volatility is a unique feature that allows the player todirectly select and change the game's volatility level in real-time through the game's settings menu or start screen. The core of this feature is to give the player powerful agency to'tune' the game's 'risk' and 'reward style' to match their own preferences and financial situation, rather than following a single 'personality' set by the developer.

Full Screen Bonus is a special payout rule that awards an additional bonus (usually a multiplier) on top of the standard prize at the visually most satisfying moment when all positions on the reels are filled with a single identical symbol. The core of this feature is that it is distinguished from a regular high-payout win, as it is an 'achievement-based reward' given for accomplishing the special condition of 'filling the entire screen'.
