Coin Volcano 2 Slot Review
Coin Volcano 2 is the sequel to the original Coin Volcano slot, released on 7 August 2025 by 3 Oaks Gaming. The Coin Volcano 2 slot expands the layout from 3x3 to 3x5 while keeping the volcano, Hawaii and coins theme. RTP is listed at 95.66% and volatility is described as Medium to High. Max win in the source table is 500x bet, which is notably lower than the original’s 2,551x figure; treat max win as depending on the casino version, since operator configurations can differ.
Bet range is $0.10-$70. The bonus toolkit is broader than in the classic game, with Hold and Win, Sticky Coins, Jackpot Coins, Mystery Symbols, Volcano Multipliers and Multiplier Cells all present. There is a Bonus Game and an Ultra Bonus Game, and a Bonus Buy option may be available in supported casino versions. Jackpots include 5 in-game tiers with a Grand Jackpot at 500x bet, though exact jackpot behaviour depends on the version.
There are no traditional free spins in the standard flow; the Hold and Win bonus with re-spins acts as the main feature round. Most players access Coin Volcano through mobile casino websites or casino apps that include 3 Oaks Gaming slots, and Coin Volcano 2 follows the same pattern on Android and iOS.
Coin Volcano 2 suits players who liked the first Coin Volcano game and want a wider grid with a more layered bonus structure, rather than a bigger max win ceiling. Because source data on max win and jackpot payouts is disputed between references, treat the exact numbers as illustrative inside your chosen casino.

Is there an official Coin Volcano app?
Yes, this is a standalone official Coin Volcano app from 3 Oaks Gaming. Most players access Coin Volcano through mobile casino websites or casino apps that include 3 Oaks Gaming slots.

| Best for | Simple coin-focused sessions | Wider grid and more bonus layers |
Coin Volcano is the classic, simpler entry: a 3x3 grid, one payline and a Hold and Win bonus with jackpot coins. Coin Volcano 2 is the updated sequel, with a 3x5 grid and a more advanced bonus toolkit that adds Ultra Bonus structure on top of the familiar coin-collect flow. Max win figures are hard to compare directly because source data is disputed, so treat them as depending on the version.
The choice comes down to intent. If you want a simpler Hold and Win session with a familiar coin theme, the original Coin Volcano slot fits. If you prefer a more advanced bonus structure and a wider grid, Coin Volcano 2 is the natural next step in the series.
Coin Volcano Bonus Features Explained
Hold and Win
Hold and Win is the core mechanic across the Coin Volcano series. Landing enough coin symbols can trigger the Hold and Win bonus with re-spins, where new coins may stick to the grid until re-spins run out or the field fills. In supported casino versions, filling the full field can award a larger prize such as a Grand Jackpot, depending on the version.
Sticky Coins
Sticky Coins are coin symbols that lock in place once landed, typically during the bonus game. They may carry cash values or jackpot tags, and additional re-spins can reset each time a new sticky coin lands. Behaviour and coin values and by game in the Coin Volcano series.
Jackpot Coins
Jackpot Coins are special coin symbols that can award fixed prizes tied to bet size. In Coin Volcano, tiers are listed as Mini 10x, Minor 20x, Major 50x, with a Grand Jackpot that source data shows at either 500x or 2,500x depending on the version. Coin Volcano 2 lists 5 tiers including a Grand at 500x bet, which may vary.
Mystery Symbols
Mystery Symbols can appear on the grid and reveal a coin value, a jackpot tier or another symbol when the bonus resolves. Mystery jackpot symbols are also mentioned in 3 Coin Volcanoes and 3 Super Coin Volcanoes. Exact reveal odds and prize pools are not specified in source data and depend on the game version.
Volcano Multipliers
Volcano Multipliers and multiplier cells can boost the value of coins during the Hold and Win round in Coin Volcano and Coin Volcano 2. Multipliers may apply to individual coin cells or trigger from volcano-themed features. Values and trigger rules depend on the game version and are not fully specified in source data.
Bonus Buy
Bonus Buy lets players purchase entry into the bonus game directly, in supported casino versions. Source data mentions costs such as 50x for the Bonus Game and 100x for an Ultra Bonus Bet, and elsewhere 30x for Hold and Win buy and 75x for Ultra Bonus Game;.
Demo Mode
Demo mode lets you try the Coin Volcano slot and other titles in the series with virtual credits, when the operator offers it. Demo availability depends on the casino and your country. It is a useful way to check volatility, bonus frequency and layout before switching to real money.
Where to Play Coin Volcano Games
Coin Volcano games are typically found in online casinos that include 3 Oaks Gaming titles in their slots library. Availability depends on the casino, operator, licence and country, so the exact list of Coin Volcano series games in your lobby can vary. Some operators list the classic Coin Volcano only; others add Coin Volcano 2, 3 Coin Volcanoes, 3 Super Coin Volcanoes, Lava Coins Hold and Win and Lava Coins 2, plus related titles like Jungle Volcano.
Most operators offer both demo and real-money modes, though demo access can be restricted in some countries or behind a login. Mobile play works through the casino’s mobile website in a browser, and in some cases through a casino app that includes 3 Oaks Gaming slots on Android or iOS. There is no confirmed standalone Coin Volcano app or Coin Volcano 2 app in the source data, so the casino app itself is the usual access route.

Expert Verdict: Is Coin Volcano Worth Playing?
The Coin Volcano series is a solid pick if you enjoy Hold and Win mechanics, coin symbols, jackpot tiers and a straightforward bonus flow rather than long free spins rounds. The classic Coin Volcano slot is the entry point, with a compact 3x3 grid and a familiar coin-collect bonus. Coin Volcano 2 is the sequel step: a wider 3x5 grid, more bonus layers and additional jackpot tiers, though max win figures depend on the version.
For expanded volcano and jackpot mechanics, 3 Coin Volcanoes and 3 Super Coin Volcanoes push the series further with multi-volcano features, eruption and grow mechanics, and Royal x2000 jackpot tiers. If you want a related, higher-potential option with free spins, Jungle Volcano sits alongside the series with a larger max win ceiling of up to 10,000x and a High volatility profile.
Try the demo first when your casino offers it, so you can feel the volatility and bonus rhythm before switching to real money. Because RTP, jackpot payouts and bonus buy costs may vary by operator and version, always check the in-game paytable in your chosen casino. There are no guaranteed wins; treat the Coin Volcano series as entertainment with a clear budget.
