Big Bass Bonanza 2.0 is a color-selection, tile-interaction system played across a fixed set of rounds. The session begins with choosing one of three colors for the ball. During play, the ball descends through color-coded tiles, including multiplier elements and additive tiles. Passing through a tile that matches the selected color increases the balance according to the tile type.

A modifier system enables limited control of the field: each round grants one modifier, and up to two modifiers can be held and activated concurrently.

At the end of the session, the accumulated balance is converted into tickets.

A customization screen provides a randomized selector for skins. Obtained skins can be activated for subsequent sessions.
