Multi-Level Bonus refers to a structure where a bonus game, like 'Pick and Win', does not end with a single choice, but requires the player to sequentially pass through multiple 'levels' to reach the final reward. The core of this feature is to provide a clear sense of 'journey' and 'progression' to the game, and to offer the ultimate sense of achievement by gradually increasing the anticipation for a larger reward with each level passed.
