3 Coin Volcanoes: stake and payout guide
Track the original coin values and the modified board separately. A longer feature caused by Life does not automatically mean that additional stakes were deducted.

What happens in 3 Coin Volcanoes
Three differently coloured volcanoes give this game its identity. Life changes the respin sequence, Multi changes values and Grow changes the available board. The result is not simply Coin Volcano with a larger number in the title: the feature can develop along three separate dimensions.
There are two full-board prize references
The published Grand is 500×, while a filled expanded board can qualify for the 2,000× Royal. The Royal condition belongs to the grown board. A screenshot of the smaller grid should not be used to imply that simply filling those starting positions awards the larger prize.
A stocked game is not necessarily the most searched game
This title appears in Australian catalogue coverage, which supports including it in a local game library. Catalogue presence does not measure how frequently Australians type its name into Google. The useful comparison here remains its three-booster feature against the simpler Coin Volcano editions.
Read a result in Australian dollars
The following worked example isolates one operation so the calculation can be followed. The stake and values are constructed inputs, separate from any account promotion or recorded result.
A$0.50 × 2,000 = A$1,000.00 illustrates the published Royal multiple. Its full-grown-board condition still applies.
Held coin positions remain; Grow can add two rows. Life renews respins when its feature applies.
A round can settle in the game currency while the funding transaction began in another currency. The final game return belongs in the round history; a processor charge belongs in the payment record. Use the two records together when explaining a balance change. This matters especially when a retained-symbol feature shows many interim values before one final total.
3 Coin Volcanoes screens and controls
Start with the occupied positions and the remaining feature counter. A coin label, a jackpot label and a collector can occupy similar-looking positions while performing different roles. Follow the final values shown after a modifier rather than adding the earlier labels again.


Separate time, value and space
Life affects the remaining opportunities in the feature. Multi affects eligible coin amounts. Grow adds two rows to the original board. Explaining all three as a generic multiplier would hide their distinct effects, especially when several boosters are active together.
3 Coin Volcanoes compared with Coin Volcano 2
These two titles are connected by their feature family or the way their game states develop. The useful comparison is the specific rule in each row: a shared theme, jackpot label or provider does not make the two games interchangeable.
| Comparison point | 3 Coin Volcanoes | Coin Volcano 2 |
|---|---|---|
| Developer | 3 Oaks Gaming | 3 Oaks Gaming |
| Layout | 4 columns × 3 rows before growth | 3 columns × 5 rows |
| Feature entry | A completed active line starts three respins | The completed middle row starts three respins |
| Persistent state | Held coin positions remain; Grow can add two rows | Bonus coins remain in their cells during the feature |
| Main mechanism | Life, Multi and Grow volcano boosters | A taller coin board with volcano multipliers and collectors |

The numbers behind the round
Start with the total stake, then follow the feature and the amount finally credited. This SM Pay review connects the published rules to the balance records an Australian reader would use to understand a round. Amounts in the worked examples are in Australian dollars; the actual account currency belongs in the game’s own display.
A useful record contains four items together: the selected stake, any separately priced mode, the round identifier and the settled return. A sequence of cascades or respins can look like many actions while still belonging to one original round. Match the complete result to the account history before interpreting the individual animations.
For a payment comparison, keep the game’s result separate from the cost of moving money. A currency conversion, deposit deduction or withdrawal fee changes the amount received by an account, but it does not change the game’s paytable. The related payment guides below explain how to compare those stages without counting the same amount twice.
Follow occupied cells and the remaining counter
The feature begins from a defined board state. Landed bonus symbols can remain in their positions while empty positions continue to take part in the respin sequence. A new symbol, collector or modifier may change both the amount displayed and the counter. Record those as separate changes: the number of occupied cells is not itself a cash value.
Questions about 3 Coin Volcanoes
What starts the main feature?
A completed active line starts three respins. Life, Multi and Grow volcano boosters.
What stays on screen during the feature?
Held coin positions remain; Grow can add two rows. Life renews respins when its feature applies. This retained information explains why a later result may depend on earlier stages of the same feature.
Which RTP and prize figure belongs to this edition?
See the help screen for the offered version. The published prize reference is 500× Grand; 2,000× Royal on the fully grown board. Match both to the full game title and selected help-screen configuration.
How should an Australian-dollar example be read?
A$ denotes Australian dollars in this article’s constructed calculations. The actual game can display another account currency. Use the currency code and the total stake shown by that game when translating a stake-based value.
