Land eight or more
Matching regular symbols pay anywhere on the board; they do not need to touch or follow a payline.

Sunken Dominion
Tumble deeper.
Live on StakeComplete game guide ↓The short version
A luminous descent into a drowned empire, where cluster wins, cascading symbols and two distinct free-spin paths keep pulling the player below the surface.
The brief was to make a treasure slot feel mysterious instead of familiar. We built a deep-sea cabinet around responsive framing, jewel-like symbols and a clear 6 × 5 tumble loop that reads instantly—even in compact popout formats.

Core loop
How the game
actually works.
Wins need eight or more matching regular symbols anywhere on the 6 × 5 board. Every winning symbol bursts, the empty spaces refill from above, and the same paid spin continues until no new win forms.
Burst the winning set
Every symbol in the winning set is removed. The remaining symbols drop and fresh symbols enter from above.
Continue the tumble
The refilled board is evaluated again. Consecutive wins advance the ordinary tumble multiplier from 1× to 2× and then 3×.
Open the Maelstrom
Four, five or six-plus Maelstrom Scatters award 10, 12 or 14 Crown Free Spins. The Leviathan path adds persistent relic multipliers.

Where the extra value enters, how it grows and when it is applied to a win.
First evaluation
The first winning board in a paid spin settles at the starting tumble multiplier.
Second winning tumble
A fresh win after the first burst advances the ordinary tumble chain.
Third tumble onward
The ordinary tumble multiplier reaches 3× and stays there for later wins in that paid spin.
Crown Awakening
A separate feature meter charges through 2×, 3× and 5×. At full charge, the Crown transforms the board toward another qualifying win and evaluates it at 5×.
Leviathan relics
Feature-only relics add into one persistent multiplier. The accumulated value applies to the current eligible win and later wins in the feature.

6 × 5 playfield
Thirty readable cells sit inside a carved deep-sea frame, leaving the win state legible against a detailed world.
Mode-led world art
Base, Crown and Leviathan modes each shift the environment while preserving the same playfield geometry.
Responsive cabinet
The controls, logo and board recompose for short landscape, popout and portrait screens rather than simply shrinking.
