Understanding the slot specifications
Max Win
The payout ceiling in the game rules, usually a bet multiplier. It is a limit, not a typical outcome.
RTP
The theoretical return over a very large number of rounds. A game may have different RTP versions; the percentage does not predict a session.
Volatility
The spread of outcomes. High volatility generally means sharper swings; it does not by itself increase RTP.
Bonus buy
Paid access to a bonus feature without waiting for the regular trigger. Price and availability depend on the game and version.
Ante Bet
A higher cost per regular spin for a changed chance of triggering a feature. This is a separate mode, rather than a bonus-round purchase.
Respins
Additional spins that may retain some symbols or accumulated conditions. The exact behaviour follows the slot rules.

Bubble Up! — game overview

Bubble Up! puts cash symbols inside growing bubble frames that collect the values they enclose.

An underwater world inside bubbles

Bubble Up! makes its underwater setting part of the rules: square bubble frames appear over the symbols and collect money icons inside them. Reef creatures fill the rest of the board and form ordinary line combinations. Two layers operate on the same grid. A spin can produce a regular win or a separate payment from money caught in a frame. One calculation follows a payline, while the other depends on the area covered by the bubble.

Ordinary symbols on the 6×6 board pay on 40 lines. Money icons are collected when enclosed by a bubble frame. Overlapping frames boost values in their shared area, so one broad collection area and several overlapping bubbles provide different possibilities within the same arrangement.

Free spins with growing frames

Three to six scatters award six free spins with one to four modifiers. Before play, these can add money symbols or scatters, increase the starting frame size, or guarantee two frames on every spin. They establish conditions for the whole feature.

Frames grow from 2×2 to 6×6. Every three feature scatters add two spins and enlarge them. A position previously outside a collection area can later become enclosed, changing the relationship between bubble size and money locations on the same underwater board.
