Coin Volcano 2 expands the original 3×3 format to a 3×5 grid and adds the Boost Bonus Game. This guide covers the original Coin Volcano.

How the Base Game Leads to the Bonus

Coin Volcano uses the middle row of its 3×3 grid as the bonus trigger.

Landing any three qualifying symbols across the middle row activates a Hold & Win feature. The result can lead into the standard Bonus Game or the enhanced Ultra Bonus Game.

Why Base Spins Do Not Pay Regular Wins

Coin Volcano does not use ordinary symbol combinations for base-game payouts.

Instead, the base phase is built around:

  • triggering the Bonus Game;
  • triggering the Ultra Bonus Game;
  • collecting Sticky Coins before a bonus begins.

The monetary results are settled through the bonus mechanics rather than conventional reel combinations.

How the Stake Affects Coin and Jackpot Values

Coin and jackpot values are expressed as multiples of the total stake.

For example:

  • a 5x Sticky Coin is worth ETB 50 at an ETB 10 stake;
  • a 20x Minor Jackpot is worth ETB 200 at an ETB 10 stake;
  • the 500x Grand Jackpot is worth ETB 5,000 at an ETB 10 stake.

Changing the stake therefore changes the monetary value of multiplier-based prizes.

Sticky Coins and the Middle-Row Bonus Trigger

Sticky Coins can appear during the base game and remain on the grid until the Bonus Game or Ultra Bonus Game begins.

Each Sticky Coin carries a value from 5x to 9x the stake.

A Sticky Coin occupying a middle-row position contributes toward completing the three-symbol bonus trigger.

Hold & Win Respins on the 3×3 Grid

The Bonus Game uses the full 3×3 grid and begins with three respins.

  1. The qualifying symbols remain locked on the grid.
  2. Three respins are awarded.
  3. New qualifying symbols stick in their positions.
  4. Every new qualifying symbol resets the respin counter to three.
  5. The feature ends when the respins reach zero or all nine positions are occupied.

Filling the complete 3×3 grid awards the 500x Grand Jackpot.

How New Symbols Reset the Respin Counter

The Hold & Win feature always returns the counter to three when a new qualifying symbol lands.

For example, if one respin remains and another symbol lands, the counter returns to three rather than continuing from one.

Existing collected symbols remain locked while the remaining empty positions continue to respin.

When the Hold & Win Round Ends

The feature ends in either of two ways:

  • all nine grid positions become occupied;
  • three consecutive respins finish without adding another qualifying symbol.

The values of the collected symbols and applicable feature effects are then combined into the bonus payout.

Bonus Game and Ultra Bonus Game

1xBet Coin Volcano Bonus

Coin Volcano has two Hold & Win modes: the Bonus Game and Ultra Bonus Game.

Both use the 3×3 collection grid and three-respin structure. The main difference is the treatment of Volcano Multipliers.

Bonus Game

The standard Bonus Game starts with three respins.

Volcano Multipliers can activate during the feature. Up to nine multiplier symbols can be added during an eruption.

Every newly collected qualifying symbol resets the respin counter to three.

Ultra Bonus Game

The Ultra Bonus Game is an enhanced version of the Hold & Win feature.

Volcano Multipliers are guaranteed during Ultra Bonus play. Mystery symbols are also guaranteed to appear during the feature.

The same 3×3 grid and collection structure remain in use.

Volcano Multipliers

Volcano Multipliers increase values on qualifying grid positions during the Hold & Win features.

In the standard Bonus Game, the Volcano Multiplier feature can activate randomly.

In the Ultra Bonus Game, Volcano Multipliers are guaranteed.

Multiple multiplier effects can build on the same position before the final feature result is calculated.

Coin Collect, Mystery and Jackpot Symbols

Coin Volcano uses several special symbol types during its feature rounds.

Symbol Function
Regular Coin Adds its displayed multiplier value
Sticky Coin Carries a 5x–9x value and remains until the bonus
Coin Collect Collects visible Coin and Jackpot values
Mystery Reveals another qualifying symbol
Mystery Jackpot Reveals Mini, Minor or Major
Mini Fixed 10x jackpot
Minor Fixed 20x jackpot
Major Fixed 50x jackpot
Grand Fixed 500x jackpot

How Coin Collect Works

Coin Collect gathers the visible Coin and Jackpot values from the grid.

After collection, the Coin Collect symbol remains locked until the Hold & Win feature ends. Volcano Multiplier effects are applied to qualifying values as part of the feature calculation.

Mystery Symbols

Mystery symbols reveal their final value during the feature settlement.

A standard Mystery symbol can transform into another qualifying symbol except a Sticky Coin.

Mystery Jackpot has a narrower function: it reveals one of three fixed jackpot symbols:

  • Mini: 10x;
  • Minor: 20x;
  • Major: 50x.

Mini, Minor, Major and Grand Jackpots

Coin Volcano has four fixed jackpots:

  • Mini: 10x the stake;
  • Minor: 20x;
  • Major: 50x;
  • Grand: 500x.

These are fixed multiplier prizes rather than progressive jackpots.

The Grand Jackpot is awarded when all nine positions of the 3×3 Hold & Win grid are filled.

For an ETB 20 stake:

  • Mini = ETB 200;
  • Minor = ETB 400;
  • Major = ETB 1,000;
  • Grand = ETB 10,000.

Coin Volcano RTP

Coin Volcano has a theoretical RTP of 95.66%.

The corresponding theoretical house edge is 4.34%.

RTP represents the calculated long-term return across a large volume of play. It does not mean that an ETB 100 spin returns ETB 95.66 or that an individual session will finish close to the theoretical percentage.

Coin Volcano Maximum Win

The maximum Coin Volcano payout is 2,551x the stake.

For example:

  • ETB 10 stake: maximum ETB 25,510;
  • ETB 20 stake: maximum ETB 51,020;
  • ETB 100 stake: maximum ETB 255,100.

The 500x Grand Jackpot is therefore not the maximum possible total feature result. Coin values, jackpot symbols and multiplier effects can combine into a larger payout up to the game’s overall 2,551x cap.
