Coin Volcano Slot Features
Coin Volcano is packed with exciting features that enhance gameplay and provide players with numerous opportunities for big wins. Each feature is designed to keep the action dynamic and engaging, making every spin a thrilling experience. Below are the key features that players can expect when diving into this volcanic adventure.
Hold and Win Feature
The Hold and Win feature is the cornerstone of Coin Volcano’s gameplay experience. This feature activates when three or more special coin symbols appear on the reels simultaneously. Once triggered, these coins lock into place, and players are granted a series of respins to collect additional coins. The initial number of respins is typically set at three, but this can be extended as new coins land.
What makes this feature particularly exciting is its potential for exponential growth. As more coins are collected, the chances of filling the entire grid increase, leading to substantial payouts. The tension builds with each respin, as players watch their coin collection grow and anticipate the possibility of triggering one of the game’s jackpots.
Sticky Coins
Sticky Coins work in tandem with the Hold and Win feature to create a truly immersive and potentially lucrative experience. When these special coins land on the reels during the Hold and Win bonus, they adhere to their positions for the entire duration of the respins. This mechanic serves multiple purposes:
- It increases the likelihood of filling the grid with coins.
- It maintains the excitement level throughout the bonus round.
- It provides a visual representation of progress towards bigger wins.
The Sticky Coins feature can be particularly rewarding when high-value coins land early in the bonus round, as they contribute their value to the final payout multiple times.
Volcano Multipliers
Volcano Multipliers add an explosive element to the gameplay, living up to the slot’s fiery theme. These multipliers can appear randomly during any spin, attaching themselves to coin symbols. When activated, they can significantly boost the value of the coins they’re associated with.
The multiplier values can vary, typically ranging from 2x to 10x, but in some cases, they can go even higher. What makes this feature truly exciting is the potential for multiple multipliers to land in a single spin or during the Hold and Win feature. When this happens, the multipliers combine, leading to the possibility of massive payouts that can reach the game’s maximum win potential of 2,551x the stake.


Mystery Symbols
Mystery Symbols inject an element of surprise and anticipation into every spin. These symbols appear as question marks or other enigmatic icons on the reels. When the reels stop spinning, Mystery Symbols transform into other symbols, potentially creating winning combinations where none seemed possible.
In Coin Volcano, Mystery Symbols can turn into any symbol except for the special coin symbols. This transformation occurs simultaneously for all Mystery Symbols on the screen, adding to the excitement as players watch to see what symbol will be revealed. The unpredictability of this feature keeps the base game engaging and can lead to unexpected big wins.
Jackpot Coins
The Jackpot Coins feature in Coin Volcano offers players the chance to win one of four fixed jackpots: Mini, Minor, Major, and Grand. Each jackpot is represented by a special coin symbol, and landing these during the Hold and Win feature is key to triggering the jackpots.
The Grand Jackpot, offering a substantial 500x stake payout, is the most coveted prize. To win this, players need to fill all nine positions on the 3×3 grid with jackpot coins during the Hold and Win feature. While challenging, the possibility of hitting this jackpot adds an extra layer of excitement to every bonus round.
Bonus Buy Feature
For players who prefer to jump straight into the action, Coin Volcano offers a Bonus Buy option. This feature allows players to purchase direct access to the Hold and Win bonus round without waiting for it to trigger naturally through gameplay.
The cost of the Bonus Buy is typically set at a multiple of the current bet, often 30x or 75x. While this represents a significant upfront investment, it guarantees entry into the bonus round, where the potential for big wins is highest. This feature is particularly appealing to high-rollers and players who enjoy the thrill of bonus rounds.
Respins
The Respins feature is intricately woven into the fabric of Coin Volcano’s gameplay, particularly during the Hold and Win bonus. Initially, players receive three respins when the bonus is triggered. However, each time a new coin lands on the reels, the respin counter resets to three.
This creates a dynamic where players can potentially enjoy an extended bonus round if coins continue to land regularly. The Respins feature not only prolongs the excitement but also increases the chances of filling the grid with coins or triggering one of the jackpots. It’s this combination of tension and potential that makes the Respins feature a highlight of the game.
Mobile Compatibility
Recognizing the growing trend of mobile gaming, 3 Oaks Gaming has ensured that Coin Volcano is fully optimized for play on mobile devices. The game’s 3×3 grid layout translates well to smaller screens, maintaining the visual impact of the volcanic theme.
The mobile version retains all the features of the desktop game, including the Hold and Win bonus, Jackpots, and Bonus Buy option. Touch controls are intuitive, making it easy to adjust bets, spin the reels, and navigate the game’s features. The responsive design ensures that Coin Volcano looks and plays great on a variety of screen sizes, from smartphones to tablets.
Free Play Mode
Coin Volcano’s Free Play mode is an invaluable tool for both new and experienced players. This mode allows users to spin the reels and experience all of the game’s features without risking real money. It’s an excellent way to:
- Familiarize oneself with the game’s mechanics and bonus features.

How to play Coin Volcano
Playing Coin Volcano is an exciting adventure that combines simple mechanics with thrilling bonus features. Here’s a step-by-step guide to help you navigate this volcanic slot and maximize your chances of erupting wins.
Step 1: Set Your Bet
Before diving into the action, it’s essential to set your bet size according to your budget and playing style. Coin Volcano offers a flexible betting range from £0.10 to £60, catering to both casual players and high rollers. Use the plus and minus buttons located at the bottom of the screen to adjust your stake. Finding a comfortable bet size allows you to enjoy the game without risking more than you can afford, ensuring a more enjoyable gaming experience.
Step 2: Spin the Reels
Once you’ve set your desired bet, it’s time to spin the reels. Click the spin button prominently displayed on the interface to set the 3×3 grid in motion. As the reels spin, they will eventually come to a stop, revealing a combination of symbols. The anticipation during this moment adds excitement to each round, as players hope for favorable outcomes that can lead to wins or trigger bonus features.
Step 3: Collect Coin Symbols
As you play, keep an eye out for coin symbols, which are central to Coin Volcano’s unique gameplay. Unlike traditional slots that rely on matching symbols, this game focuses on collecting coins. Landing three or more coin symbols in the middle row activates the Hold and Win bonus game, where players can significantly increase their winnings. The thrill of watching for these special symbols adds an engaging layer to the gameplay.
Step 4: Engage in the Hold and Win Feature
When you successfully collect three or more coin symbols, the Hold and Win feature is triggered, bringing an electrifying twist to your gameplay. During this feature, the activating coin symbols lock in place while you receive three respins. If additional coin symbols land during these respins, they also stick in place and reset your respin counter back to three. This mechanic creates opportunities for accumulating multiple coins and maximizing potential payouts.
Step 5: Watch for Special Symbols
While in the Hold and Win feature, be vigilant for special symbols like Sticky Coins, Mystery Symbols, and Jackpot Coins. Sticky Coins remain fixed during respins, enhancing your chances of filling the grid with valuable symbols. Mystery Symbols can transform into other symbols when revealed, potentially completing winning combinations. Jackpot Coins are particularly enticing as they can lead to significant payouts if you manage to fill all positions on the grid with them.
Step 6: Utilize Volcano Multipliers
Volcano Multipliers add an extra layer of excitement during gameplay by randomly appearing alongside coin symbols. When these multipliers are present, they increase the value of any associated coins, potentially leading to substantial wins. The multipliers can vary in value and can even stack if multiple multipliers land on a single spin or during the Hold and Win feature. This unpredictability enhances the thrill of each spin as players anticipate explosive payouts.
Step 7: Aim for the Ultra Bonus Game
For those who want an even more intense experience, Coin Volcano offers an Ultra Bonus Game that can be triggered randomly or purchased directly through the Bonus Buy feature. This special game mode provides enhanced features such as guaranteed Volcano Multipliers and increased chances of retriggering bonuses. Engaging in this mode can significantly elevate your potential for big wins and adds an extra layer of strategy for players looking to maximize their gameplay.


Step 8: Manage Your Bankroll
Effective bankroll management is crucial for a sustainable gaming experience. Keep track of your wins and losses throughout your session, setting personal limits on how much you’re willing to spend or win before taking a break. Playing responsibly ensures that you enjoy Coin Volcano without experiencing undue financial stress. Remember that gambling should be fun; setting limits helps maintain that enjoyment.
Step 9: Explore the Paytable
Before diving deep into gameplay, take some time to review the paytable available within the game interface. The paytable outlines the value of different coin symbols and special features, helping you understand potential payouts for various combinations. Familiarizing yourself with this information allows you to make informed decisions about your bets and strategies as you play.
Step 10: Consider Using Autoplay
If you prefer a more relaxed approach or want to enjoy continuous spins without manually clicking each time, consider utilizing the Autoplay feature. This option allows you to set a predetermined number of spins at your chosen bet level automatically. You can also set limits on losses or wins during autoplay sessions, ensuring that you maintain control over your gameplay while enjoying uninterrupted action in Coin Volcano.
