Coin Volcano 2 Rules

This game does not use traditional high/low line symbols. Instead, the feature grid fills with special coins and utility icons. Values are displayed as X of total bet and are collected at the end or via Coin Collect. High-value icons: Major 50×; Minor 20×; Mini 10×; Sticky Coin 5×–9×; top regular Coin 4×. Lower-value icons: Regular Coins 0.5×–3×; Coin Collect (utility); Volcano Multipliers (utility); Mystery and Mystery Jackpot (revealers).

HOW THE SLOT WORKS

The base mode contains no standard paying symbols, all activity is tied directly to the feature rounds.
Every payout is possible only during the Bonus Game or the Ultra Bonus Game sessions.
When three symbols land on the middle row, the reels launch either the Bonus or the Ultra Bonus mode.

LOCKED COIN BONUS

The Sticky Coin can randomly appear during the base game and will remain on the reels until either the Bonus Game or the Ultra Bonus Game is activated.
Such coins bring instant rewards ranging between 5× and 9× the total bet, adding extra value before the special round begins.

STICKY GRID SYMBOLS

Sticky features that land on the middle row do not improve the chances of triggering the Bonus or Ultra Bonus rounds.
When you change the bet size, all currently active Sticky Coins are removed from the reels before the next spin starts.

BONUS FEATURE

During the Bonus and Ultra Bonus rounds, every Bonus symbol that lands stays fixed on the reels until the end of play.
At the start you receive three re-spins, and each new Bonus symbol that appears resets the counter back to three.
The feature continues either until no spins remain or until all fifteen reel positions are fully covered with Bonus icons.

COIN REWARDS

Standard coin symbols deliver payouts that vary between 0.5× and 4× the total stake, providing frequent smaller wins throughout the feature rounds.
Alongside them, special jackpot coins can appear
- Mini worth 10×
- Minor worth 20×
- Major worth 50×
each of which pays its corresponding fixed prize whenever it lands during the Bonus or Ultra Bonus Game.

MYSTERY TRANSFORM

The Mystery symbol has the ability to change into any other icon on the reels, making it a flexible tool that increases overall variety and potential combinations.
Its transformation is revealed only after the feature round ends, adding suspense to the outcome of every spin in Bonus or Ultra Bonus mode.

MYSTERY JACKPOT

The special Mystery Jackpot coin can only turn into one of the fixed jackpots: Mini, Minor, or Major, each providing its corresponding reward when revealed.
Just like the regular Mystery, this symbol opens at the end of the feature, uncovering whether a guaranteed jackpot prize has been hidden inside.

COIN COLLECT FEATURE

The Coin Collect symbol instantly gathers all coin and jackpot values that are present on the reels, crediting them immediately to the player’s total.
If multipliers are active, they are applied to every coin and jackpot prize before the collection is finalized, making the payout potentially much larger.
After performing the collection, the Coin Collect symbol itself stays locked in position on the reels until the Bonus Game or Ultra Bonus Game finishes.

GRAND JACKPOT

When all fifteen reel positions are filled with any type of symbol, the game awards the Grand Jackpot worth 500× the total bet placed.
This massive prize is always added on top of the total winnings accumulated during the Bonus Game or Ultra Bonus Game session.

VOLCANO MULTIPLIERS

The Volcano Multiplier effect may activate randomly during the Bonus or Ultra Bonus rounds, dropping fiery multipliers onto the reels.
Each multiplier increases the value of the coin it lands on by ×1, and if several fall on the same cell, their values stack together.
All collected multipliers are applied to coin prizes only at the end of the feature, making the final payout significantly higher.

ULTRA BONUS MODE

The Ultra Bonus round can be triggered at random during the main game, opening access to enhanced rewards and fiery action on the reels.
At the very start of this feature, the Volcano Multipliers effect is guaranteed to activate, immediately boosting coin positions with extra value.
Throughout the Ultra Bonus, the likelihood of multipliers striking again is higher than usual, giving players more chances to build up stacked rewards.

BUY BONUS OPTION

Players can instantly purchase entry into the Bonus Game for 50, the Ultra Bonus Game for 100, or the Boost Bonus Game for 300, depending on preference and balance.
After the purchase, the chosen feature begins immediately at the current stake level, with Sticky Coins from the base game not carried over into the bought round.
If the balance is insufficient, the option is unavailable, and all winnings in the purchased round are tied to the triggering bet size only.

BOOST BUY BONUS

The Boost Bonus Game becomes available only through the Buy Bonus option, guaranteeing Volcano Multipliers from the very beginning of the feature.
Within this mode, every multiplier starts at ×5, with the chance of additional Volcano Multipliers re-triggering at a higher frequency than usual.
Each time they land, multipliers stack to increase coin values further, ensuring that the Boost Bonus round delivers amplified payout potential.

How to Play Coin Volcano 2

Set your stake and spin. The base game contains no regular paying symbols; focus on the middle row trigger: landing any three symbols on the middle row activates the Bonus Game or Ultra Bonus Game. Sticky Coins worth 5×–9× can appear randomly and stay until a feature triggers, unless the stake is changed, which removes them. When the feature starts, you receive 3 re-spins. Every time a new symbol lands (Coin, jackpot coin, Coin Collect, Mystery, etc.), it sticks and the re-spin counter resets to 3. If no new symbols land, the counter decreases by one. The round ends when re-spins reach zero or when all 15 positions are filled. During the feature, regular Coins carry 0.5×–4× values. Mini (10×), Minor (20×), and Major (50×) can also appear. Coin Collect instantly gathers all visible Coin and Jackpot values and then remains on the grid until the end of the feature. Volcano Multipliers can randomly hit positions; each hit increases the position’s coin multiplier by ×1, and multiple hits to the same position stack. At the end of the feature, multipliers are applied to coins and jackpots before collection. In Ultra Bonus, a Volcano Multipliers trigger is guaranteed at the start, and the chance to re-trigger Volcano Multipliers events is higher. If all 15 positions are filled with any symbols, you are awarded the GRAND JACKPOT of 500× total bet in addition to the collected amount. Buy options are available: Bonus (price 50.00), Ultra (100.00), and Boost Buy (300.00). Boost Buy guarantees Volcano Multipliers at the start, increases each Volcano hit by ×5, and ensures a minimum ×5 multiplier during that round.

lava coins, sticky luck, and a 500× finish line

Grabbed a welcome deal and basically “played Coin Volcano 2 with bonus” — no deposit, 100 FS style promo. First impression: loud molten vibes, fat gold coins, and that middle-row bait where three symbols can fire the feature. No regular pays in base, so every spin feels like waiting for the gates to open. My Ultra Bonus came from the promo run and instantly popped a Volcano Multipliers hit (it’s guaranteed there). Coins started sticking: 0.5×, 2×, a cheeky Mini 10×, then Coin Collect swept the board — super satisfying. Another volcano slammed the same spot, stacking the cell multiplier; end-of-round math juiced the total way more than I expected. Closest heartbeat moment: 14/15 with a Major 50× parked, one spin left — my heart stopped — but no final coin, so no 500× Grand. Still walked with a chunky win thanks to the stacked multipliers and a Collect timing that felt clutch. Vibe check: volatile and streaky, but when Volcano Multipliers chain and Collect shows up, it’s pure madness. I’d play again, especially with Boost Buy if the budget allows — ×5 per volcano hit and min ×5 multiplier sounds spicy.
