Game information

Theme

The game Coin Volcano 2 once again takes players on an adventure to a tropical island where a massive erupting volcano looms nearby. The game’s theme focuses on the immense fiery power of nature, with the volcano serving as both a visual centerpiece and a metaphor for potential explosive multiplier wins. Although the game itself lacks a deep storyline or narrative, the pleasant volcanic background and molten coins create an exciting and engaging atmosphere that reflects the essence of untamed natural forces. The simplicity of the theme and interface allows players to focus on the gameplay, enjoying pleasant and dynamic volcano-style animations

Graphics, Sound, and Animation

Let’s talk about the visual component of Coin Volcano 2. In the new version, the graphics have become even brighter and more visually pleasing for the user. The volcano image has been updated; now it rises to the left of the grid, and with each spin, you can see special visual effects that create additional atmosphere along with pleasant multipliers.

The color tones of the graphics resemble fire, and lava effects add depth to the gameplay.

The animation in Coin Volcano 2 is pleasant and smooth; coins lock in place during bonus features, and volcano eruptions enhance immersion in the game. At the same time, the sound doesn’t lag behind the animation and creates a complete picture that keeps players spinning from one spin to another.

Pros and Cons of Coin Volcano 2

Coin Volcano 2 Slot Features

Hold and Win Feature

The main feature in the game is Hold and Win; it becomes the cornerstone of Coin Volcano 2’s gameplay. How to activate the feature? This feature is triggered when three or more special coin symbols simultaneously appear on the reels. After activation, these coins are locked in place and players get the opportunity to spin the reels to collect additional coins, including special symbols. Initially, the number of respins is three, but when new coins appear, the counter resets to the original value and players again have three spins available, until they run out.

What is special about the Hold and Win feature??

The special feature of this function is its potential; players can increase the number of spins as coins appear, thereby you can fill the entire grid, which can lead to significant payouts. Also, with each spin, you have a chance to increase your winnings thanks to multiplier cells. If a player manages to fill the entire grid, they get a chance to win the main jackpot of the game.

Sticky Coins

Now I will tell you about another important feature in this game—Sticky Coins. They work in tandem with the Hold and Win feature, creating a truly exciting and profitable gaming experience. When these special coins land on the reels before the Hold and Win bonus, they remain in place until you activate the bonus round, thus increasing your potential winnings.

Thus, this mechanic serves several purposes:

• It increases the likelihood of filling the grid with coins.
• It maintains the level of excitement throughout the bonus round.
• It provides a visual representation of progress toward larger wins.

The Sticky Coins feature can be especially beneficial when high-value coins appear at the beginning of the bonus round, as they contribute their value to the final payout multiple times.

Visually, these coins look different, and you can familiarize yourself with them below in the paytable.

Volcano Multipliers

Volcano Multipliers or multiplier cells add an element of unpredictability and explosiveness to the gameplay that matches the slot’s theme. During the bonus game, these multipliers can appear randomly during any spin and are tied to a specific cell. If multiple multipliers appear in one cell, their values are summed. This feature can significantly increase the value of coins and the final win.

Mystery Symbols

Mystery Symbols are one of the features of this game that also add an element of unpredictability and anticipation to each spin. These symbols appear on the reels as a lava ball with a question mark. When the bonus round ends, each Mystery Symbol can turn into another symbol, including Grand Symbols or Mystery Jackpot.

Multiple different or identical Mystery Symbols can appear on the playing field simultaneously, making the unpredictability of this feature make the main game more exciting and unique in each round.

Jackpot Coins

One of the interesting features of Coin Volcano 2 is that any player, regardless of their initial bet or entry line into the bonus round, has a chance to win one of four fixed jackpots: Mini, Minor, Major and Grand. Each jackpot corresponds to a special coin on the playing field, and landing these symbols during the bonus round is the key to success and winning the maximum jackpot (Grand Jackpot) of 500x the bet size.

To win the Grand Jackpot, you need to fill all 15 cells on the playing field during the Hold and Win feature. Although this may seem difficult, many players manage to do it, so this feature definitely adds excitement to each bonus round.

Bonus Buy Feature

For players who don’t want to waste time waiting for coins to trigger the bonus, Coin Volcano 2 offers the “Bonus Buy” feature.

The cost of buying the bonus usually depends on a multiple of the current bet. Also, note that in the second version of Coin Volcano, a special Boost round has been added:

Currently, “Bonus Buy” has three options:

• 50x—for activating the regular bonus round;
• 100x—for activating Ultra Bonus;
• 300x—for activating the Boost feature added in the new game;

Respins

The next feature I will review is the Respins feature, which is one of the most frequently occurring features throughout Coin Volcano 2 gameplay, especially during the Hold and Win bonus.

As I mentioned earlier, at the beginning of the round, players receive three respins. With each respin, one is subtracted from the counter, but if any symbols land on the playing field, the counter resets to three. This continues indefinitely until the respin counter on the screen stops at zero.

This feature creates dynamics where players can enjoy the extension of the bonus round and the potential increase in the final win at the end of the round.

Mobile Compatibility

In today’s world, an important element of a successful game is the ability to play from a mobile device, be it a tablet or phone. The game developer 3 Oaks Gaming has ensured full optimization of Coin Volcano for mobile devices, on Android family tablets, on phones and iOS tablets.

The 3×5 playing field looks great on small Android and iPhone screens while maintaining the main feature—the volcanic theme. Playing Coin Volcano 2 from a mobile phone gives you access to the full version without limitations, including all bonus systems, jackpots, and the “Buy Bonus” option.

In conclusion, I note that the adaptive design of the game guarantees that Coin Volcano 2 looks and works excellently on different screen sizes, from smartphones to tablets.

Free Play Mode

Can you play Coin Volcano 2 for free? Yes! Like all games from 3 Oaks, the new game also supports free mode.

This feature will be useful for:

• New players who want to immerse themselves in the atmosphere of the volcanic slot and try new features

Game Rules

The game offers a unique approach to traditional slot gameplay. Instead of matching symbols in a line, players aim to collect coin symbols to activate the Hold and Win feature. Understanding the basic mechanics of the game is key to success and maximizing your chances of explosive wins.

Basics

In the game from provider 3 Oaks Gaming, executed in a volcanic Hawaiian theme, there are no standard symbols and familiar paylines—instead, the entire mechanics are built around special bonus features. The base game does not provide regular wins: all symbols are active exclusively in bonus and ultra-bonus games. The trigger for launching one of the bonus phases is the appearance of any three symbols on the middle line of the reels (3×5 grid). The game offers high volatility and a maximum win of up to 500x the bet, including five built-in jackpots, among which is the Grand Jackpot.

The bonus game represents a “Hold and Win” mode with respins, where activated symbols are fixed in their positions, and the remaining reels spin again. Special symbols are active during bonus phases: Sticky Coins, Mystery Symbols, jackpot symbols, and multipliers, as well as cells with volcanic multipliers that enhance the win. Traditional free spins are absent—instead, players receive respins within the bonus games. The bonus purchase function is available: for 50x, 100x or 300x the bet, you can instantly enter the Bonus, Ultra-Bonus game or the improved version of the bonus respectively. The game is compatible with mobile devices and supports autoplay, with a minimum bet of just $0.10.

Symbols

In this game, there are no traditional game symbols such as cards or thematic images typical for most slots. Instead, all symbols have functional value and are active exclusively in bonus modes—the Bonus and Ultra-Bonus games. Key symbols include Sticky Coins, which lock onto the reels and participate in respin series, and Jackpot Coins—special symbols that bring one of five fixed jackpot values, including the Grand Jackpot equal to 500x the bet. Mystery Symbols also appear, which during the bonus game randomly reveal themselves, turning into other valuable symbols and increasing the win potential.

Additionally, during bonus phases, multiplier cells appear—Volcano Multipliers and Multiplier Cells, which increase the win amount when activated. These multipliers are summed or multiplied depending on the game conditions, creating potentially large payouts. It is important to note that neither wilds nor scatter symbols are used in the game—the entire mechanics are built around symbols with bonus functions. Thus, each symbol in the bonus game plays an active role, forming a dynamic and tense gameplay with high potential for cumulative wins.

Paytable

We present to your attention the paytable of Coin Volcano 2. One of the key features of the game is the absence of classic winning combinations—instead, the entire mechanics focus on the value of coins appearing on the playing field within bonus modes.

The game uses various types of coins, including Sticky Coins and Jackpot Coins, each carrying certain value and potentially bringing significant payouts depending on the course of the bonus game. Some coins activate jackpots—including the Grand Jackpot at 500x the bet—adding excitement and increasing the potential for large wins right from the first respins.

How to play Coin Volcano 2

Conquer the volcanic element of the slot, turning every spin into a catalyst for lava payouts! Mastering Coin Volcano 2 is not just a game, but strategic interaction with Sticky Coins, Volcano Multipliers and Jackpot Cells dynamics: learn to catch the moment when Mystery Symbols reveal the path to the Grand Jackpot, and respins in the bonus phase create a chain reaction of multipliers up to 500x. Following our guide, you will not only understand the mechanics—you will learn to program the volcano for explosive combinations, where even three symbols on the middle line can trigger an ultra-bonus avalanche capable of increasing your bankroll many times over. Are you ready to become the one who tames the fiery element and takes the maximum from each eruption? 🌋

Step 1: Set your bet

Before diving into the volcanic adventure of Coin Volcano 2, it’s important to properly set your bet. The range varies from modest $0.10 to impressive $70, making the slot ideal for both beginners and experienced players. Adjust the amount based on your bankroll and strategy: low bets will allow you to explore the lava reels longer, while high bets increase your chances of big jackpots. Remember that the bonus purchase function (50x–300x bet) requires a reserve of funds, so proper bankroll management is key to long and profitable gameplay.

Step 2: Start the reels

Press the “Spin” button to activate the 3×5 grid with unique lava reels. Unlike classic slots, there are no familiar paylines here—wins are formed through special symbols and bonus mechanics. Watch the middle horizontal line: this is where three identical symbols will trigger Hold and Win. Every spin is a step toward explosive multipliers and jackpots, so even minimal bets can lead to a maximum win of 500x.

Step 3: Collect coin symbols

Your main goal is to accumulate three or more coin symbols on the middle line. These symbols come in different types: Sticky Coins, Jackpot Coins, and Mystery Symbols. Sticky Coins remain in place until the bonus is activated, increasing your chances of launching Hold and Win. Don’t miss the moment: even one high-value coin at the beginning of the round can become the foundation for a respin chain and a big win.

Step 4: Activate the Hold and Win feature

As soon as three coin symbols appear on the screen, the Hold and Win bonus round will start. All activated coins will be fixed, and you will receive 3 free respins. Each new coin symbol resets the counter to three, extending the round. Fill the grid to qualify for the Grand Jackpot (500x), or collect Volcano Multipliers cells to multiply your win. Remember: the more coins, the higher the chance of an explosive combination!

Step 5: Watch out for special characters

During bonus rounds, key symbols appear that determine success:

• Mystery Symbols (lava balls with “?”) turn into jackpot coins or multipliers.
• Jackpot Coins provide access to five fixed jackpots, including Mini (5x) and Grand (500x).
• Sticky Coins remain in place even after the bonus ends, speeding up the reactivation of Hold and Win.
  These elements create unpredictability and increase the win potential many times over.

Step 6: Use volcanic multipliers

Volcano Multipliers are your main ally in Coin Volcano 2. They randomly appear in cells during respins and are summed when reappearing in the same position. For example, a 2x + 3x multiplier becomes 5x, multiplying the value of all coins in that cell. Watch the volcano eruption animation—it signals the appearance of new multipliers. The longer the bonus round lasts, the higher the chance of collecting a multiplier chain up to 500x!

Step 7: Aim for the Ultra Bonus Game

For maximum return, activate the Ultra Bonus Game—an enhanced version of Hold and Win with a higher concentration of jackpot symbols and multipliers. It can be launched in two ways:

1. Naturally, by collecting 4+ coin symbols in the base game.
2. Through bonus purchase for 100x the bet (quick entry without waiting).
   Ultra Bonus increases your chances of filling the grid and winning the Grand Jackpot, making every respin maximally profitable.

Step 8: Manage your bankroll

The slot has medium volatility, so it’s important to strategically allocate your budget:

• Beginners: bets from $0.10–$1 with a focus on learning mechanics in demo mode.
• Experienced players: bets $10+ to activate Boost Bonus Game (purchase for 300x).
  Use autoplay with loss/win limits to avoid impulsive decisions. Remember: the maximum win is limited to $135,000, but the path to it requires patience and calculation.

Step 9: Study the payout table

Before playing, familiarize yourself with the paytable in the “i” section:

• Sticky Coins—from 5x to 9x the bet.
• Jackpot Coins—Mini (5x), Minor (20x), Major (100x), Grand (500x).
• Mystery Symbols—transform into jackpots or multipliers.
  This will help you understand which symbols are priority for collection and how to combine them with Volcano Multipliers for maximum return.

Step 10: Configure autostart

For comfortable gameplay, activate autoplay (up to 1000 spins). Set stop conditions:

• Upon winning 50x+ the bet (profit fixation).
• Upon activating Hold and Win (manual bonus control).
• Upon losing 20% of the deposit (bankroll protection).
  This feature is especially useful for testing strategies in free mode or when playing with low bets, saving time and maintaining control over the process.

All three games combine fixed prizes, sticky symbols and explosive bonuses in unique thematic settings.

Conclusion: Is Coin Volcano 2 worth playing?

With you was José Fernández, and after playing hundreds of spins in Coin Volcano 2 for real money and in demo mode, I have confirmed: this slot is not just “volcanic graphics,” but a carefully balanced risk and reward system. Yes, the 500x maximum win lags behind “monsters” like Gates of Olympus, but here every detail works for your success. For example, Volcano Multipliers in the Ultra Bonus Game don’t just sum up—they multiply your chances of a jackpot, which I verified over 30+ sessions. And Mystery Symbols? In 40% of cases, they turned into Major or Grand Jackpot if 10+ cells were filled with coins. RTP 95.66% is noticeable even with minimal bets: over a week, I never ended up in the red with proper bankroll management. I recommend ignoring loud promises of “instant jackpots”—Coin Volcano 2 values those who know how to wait: sticky coins in the base game and respins in Hold and Win create chains where even $0.10 spins hit 50x+. This is not a slot for impulsive bets but a strategic game where the volcano pays those who understand its rhythm.
