Coin Volcano 2

Coin Volcano 2 expands the hold-and-win formula from its predecessor onto a 3x5 grid, stretching the playfield to 15 positions and pushing the top win to 5,000x your stake. High volatility from 3 Oaks, a 95.76% RTP, and an erupting volcano that stacks multipliers on locked coins make the bonus rounds in this slot more complex than the original. It runs on desktop and mobile at Wild.io, accepts major cryptocurrencies, and the bonus buy options give you three different entry points into the Hold and Win round.

What is Coin Volcano 2?

Coin Volcano 2 is a 3x5 video slot from 3 Oaks with a 95.76% RTP, high volatility, and a top win of 5,000x your bet. It builds on the hold-and-win mechanic of the original Coin Volcano by expanding the grid to 15 positions, adding a fifth jackpot tier, and offering three distinct bonus buy costs for different levels of feature intensity.

The 3x5 grid is the defining upgrade over the original. Fifteen sticky positions instead of nine means the Grand Jackpot condition, filling the entire board, is a harder target but the reward reflects that. High volatility here is genuine: the longer grid requires more coins to activate the Grand payout, and base game spins between bonuses can run without any win. The session is structured around the bonus rounds.

Coin Volcano 2 keeps the Volcano Multiplier mechanic from the first game but applies it to a larger board. The volcano on the left erupts one or more times during the Hold and Win respins, randomly boosting multipliers on locked coin positions. The larger grid gives more positions to boost, and with the 5,000x ceiling those stacked multipliers across 15 positions have more room to compound.

Who will enjoy this game the most?

You will probably enjoy this game if you like:

• High volatility players who are comfortable with extended base game spins between bonuses
• Hold-and-win fans who want more positions and higher jackpot potential than the 3x3 original
• Jackpot slots players chasing five jackpot tiers including the Grand at 500x total fill
• Bonus buy slots players who want to choose their risk level: standard, mid, or Ultra bonus entry
• Crypto casino players comfortable with bet ranges starting at $0.10 and up to $70

How To Play Coin Volcano 2 Slot - Step By Step

Head to Wild.io and create a free account to start playing Coin Volcano 2.

1. Log in or register at Wild.io and deposit your preferred cryptocurrency. The payment methods page lists all supported coins including Bitcoin, Ethereum, USDT, Litecoin, and several others.
2. Find Coin Volcano 2 in the games library by searching or filtering by the 3 Oaks provider. Launch the game to play for real funds, or open demo mode first to see how the 3x5 grid and Hold and Win behave.
3. Set your bet. Coin Volcano 2 has one active payline on its 3x5 grid. Bets range from $0.10 to $70 per spin.
4. Spin the base game. The objective is the same as the original: land three or more coin symbols to trigger the Hold and Win. No coins on the active line means no payout.
5. When the Hold and Win begins, all landed coins lock in place across the 15 positions and three respins start. Every new sticky coin resets the counter to three.
6. During the bonus, the volcano may erupt and assign multiplier increments to random coin positions. The same position can receive boosts from multiple eruptions; all multipliers apply at payout.
7. If all 15 positions fill before the respins expire, the Grand Jackpot activates as a bonus payout in addition to all individual coin values. Alternatively, use the bonus buy to purchase entry at 50x, 100x, or 300x your bet for standard, mid-tier, or Ultra bonus modes.

You can also deposit using various supported payment methods.

Coin Volcano 2 Slot Theme & Graphics

Coin Volcano 2 retains the volcanic island setting of the original but scales the visual presentation to match the wider grid. The 3x5 reel sits within a more detailed volcanic environment: molten lava channels frame the reels, and the eruption animations cover more of the screen when the Volcano Multiplier fires.

Coin art across the 15 positions uses the same gold-and-fire palette as the original, with jackpot coins distinguished by colour grade. The Mystery and Jackpot Mystery symbols pulse with an amber glow that contrasts clearly against the darker reel background, making their locations easy to track during a live bonus round.

Mobile performance holds up across the larger grid. Portrait mode places the 3x5 layout vertically with the volcano to the left or beneath the reels, depending on screen ratio. The eruption effect is retained without frame-rate cuts, and all five jackpot tiers remain readable in coin form.

Coin Volcano 2 Slot Symbols & Paytables

Coin Volcano 2 runs entirely on bonus symbols: there are no traditional paying combinations in the base game. All payouts come from the Hold and Win round, where each sticky coin type carries a specific role. The expanded 15-position grid means more types of symbols can be visible at once, and knowing what each does during the respins directly affects how you read the bonus as it develops.

Low Value Symbols

Standard prize coins are the majority symbol on the 3x5 grid. Each gold coin carries a cash value from 0.5x up to 4x your stake and locks into its position the moment it lands during the Hold and Win. They drive the respin resets that keep the bonus alive, and every position they occupy at round end pays its face value. With 15 possible positions, a grid populated mainly by standard coins and a few volcano multiplier boosts can still build meaningful payouts through volume.

High Value Symbols

Jackpot coins escalate through five tiers: Mini at 10x, Minor at 20x, Major at 50x, and Grand at 500x for filling all 15 positions. A fifth jackpot level sits between Major and Grand as an additional prize tier in this sequel. Each jackpot coin resets the respin counter when it lands, extending the bonus and giving the remaining positions more time to fill. The Grand jackpot only pays its 500x value when it is the symbol that completes all 15 grid positions, making full-board completion the condition that unlocks the 5,000x total win ceiling when combined with volcano multiplier stacking.

Special Symbols

The Mystery symbol is a deferred wildcard: at the end of the bonus round, it transforms into any bonus coin type except a plain prize coin, adding a late-stage unknown to open positions. The Jackpot Mystery symbol resolves exclusively into Mini, Minor, or Major jackpot coins, never the standard prize tier. The Coin Collect symbol acts as a mid-bonus banking mechanism: it collects all values of currently locked coins on the board, sticks in place itself, and resets the respin counter. Banking mid-bonus through the Collect symbol protects accumulated prize values from being lost to expiring respins, which matters more on the 15-position grid where full completion takes longer.

Coin Volcano 2 Bonus Feature & Special Features

Hold and Win Bonus

The Hold and Win bonus in Coin Volcano 2 follows the same core structure as the original but operates on a 15-position 3x5 grid. It triggers when three or more coin symbols land during a base game spin. All coins lock in place, three respins begin, and every subsequent sticky coin that lands anywhere on the 15 positions resets the counter to three. The round ends when respins run out or all 15 positions are filled. Final payouts sum every locked coin's face value. Completing all 15 positions adds the Grand Jackpot as a separate prize. The larger grid makes full completion harder to achieve than on the 3x3 original, but it also means more opportunities for high-value jackpot coins and Collect symbols to land in ways that materially shift the final payout.

Volcano Multiplier Feature

The Volcano Multiplier is a random event during Hold and Win respins. When activated, the volcano on the left side of the game erupts and places one or more multiplier increments on randomly selected locked coin positions across the 15-position grid. A position can receive boosts from multiple eruptions within the same bonus: multipliers stack additively on that position. The multiplier applies to the coin's face value at payout, so a coin sitting on a volcano-boosted position pays a multiple of its face value. Across a grid with multiply-stacked positions and mid-to-high jackpot coins, this is the mechanism that bridges the gap between a standard Hold and Win payout and the game's 5,000x theoretical ceiling.

Ultra Bonus Game

The Ultra Bonus Game is a variant Hold and Win round that triggers randomly or via the premium bonus buy option. Its distinction is a guaranteed Volcano Multiplier activation at the very start of the round, before any respins take place. The grid enters the respins phase already carrying multiplier boosts on at least some positions, which sets a higher floor for the bonus. Any coins that land subsequently interact with those pre-placed multipliers, and further eruptions can add more. This elevated starting state is the reason the 300x bonus buy price point exists: buyers are purchasing the guaranteed multiplier opening, not just hold-and-win access.

Bonus Buy

Coin Volcano 2 offers three distinct bonus buy tiers: 50x your bet for standard Hold and Win access, 100x for a mid-tier entry with enhanced starting conditions, and 300x for the Ultra Bonus Game with its guaranteed Volcano Multiplier opening. Each tier is a different risk-reward proposition. The standard entry matches what you would get from a natural trigger; the Ultra entry adds the guaranteed multiplier setup. This tiered approach lets you choose how much of your session budget to allocate to any single bonus purchase based on the size of win you are targeting. Regional availability may apply.
