3 Oaks, known for their mastery in the Hold and Win slot domain, have launched the 2024 Coin Volcano online slot which we were eager to review. The 3×3 layout is reminiscent of another Hold and Win slot, 9 Coins from Wazdan, primarily due to the absence of regular symbols in both. Both games focus on special symbols and bonus features, creating a unique gaming experience. The audiovisual design of Coin Volcano is similar to 9 Coins, with the only slight thematic element being a volcano next to the playing field. Gameplay is the main focus for both games. Coin Volcano offers medium volatility and a solid 2,551x max win, with the top fixed jackpot at 500x the bet. The betting range of £0.10 to £60 per spin caters to all bankroll sizes. The theoretical RTP is 95.66%, below the industry average of 96%. Comparatively, 9 Coins outperforms Coin Volcano in all aspects, including a higher RTP of 96.06%. Coin Volcano only features special symbols in the form of coins, and you can trigger the Hold and Win feature by landing 3 special symbols on the middle row. The Hold and Win feature includes 3 respins that reset with each landed symbol. Jackpot coins can pay out 10x, 20x, or 50x your bet, and if you fill the board with symbols, you win the Grand Jackpot, worth 500x your bet. There are also mystery symbols and random Coin Collect features for instant wins, as well as random Volcano Multipliers for win multipliers. You can also trigger the Ultra Bonus Game with guaranteed Volcano Multipliers. Two Buy Bonus options give you direct access to the game’s bonus features for a set fee. In conclusion, it’s evident that 3 Oaks was inspired by Wazdan’s 9 Coins slot in designing Coin Volcano. However, 9 Coins outperforms Coin Volcano in most areas, making it the preferred choice.
