Earn with Coin Volcano: A Thorough Review of the 3 Oaks Gaming Slot Machine
Coin Volcano by 3 Oaks Gaming is a vibrant video slot inspired by the untamed power of nature and the legend of molten lava. Visually, the game presents a lush jungle surrounding an erupting volcano, where coins burst forth instead of molten rock, creating an unforgettable sense of adventure.
The developers paid special attention to detail: every icon, whether a classic coin or a special jackpot symbol, features its own animation and sound effect. Immersion is enhanced by dynamic effects—cracks in the ground and subtle vibrations of the reels heighten excitement with each potential win.
Coin Volcano runs smoothly on all popular platforms—Windows, macOS, iOS, and Android—thanks to its adaptive HTML5 client. The game maintains high performance and full functionality whether you play on a desktop monitor or a smartphone screen.
Deep Slot Mechanics Overview
The Coin Volcano slot uses a classic 3×3 grid combined with modern Hold and Win technology. A regular spin serves as a prologue; the real action unfolds during the Hold and Win bonus, where players hunt for “volcanic” coins with fixed rewards.
Landing three scatter symbols in the center row triggers the bonus round. The screen shifts, and your symbols lock into place. Empty positions are then filled one by one with volcanic coins, each bearing a multiplier between 5× and 9× your original bet.
How long does the bonus last? The round continues as long as new winning symbols appear, with no upper limit on additional spins. This gives you a shot at the Grand jackpot or substantial payouts through successive Volcano multipliers.
Classification of the Game Type
Coin Volcano is a high-volatility video slot featuring Hold and Win mechanics, where wins form not only through traditional symbol combinations but also by collecting special coins. High volatility means base-game wins are infrequent but can be very substantial when they occur.
The slot’s RTP ranges from approximately 96.5% to 97.2%, making it a competitive option among Hold and Win titles. Many rivals offer RTPs between 94% and 96%, so Coin Volcano stands out with a higher long-term payout potential.
With four fixed jackpots—Mini, Minor, Major, and Grand—the game appeals to risk-takers seeking sudden windfalls. The compact 3×3 grid keeps gameplay focused on the quest for those lucrative volcanic coins.

Basic Principles
- Format: Grid of 3 columns × 3 rows.
- Bets: Fixed number of paylines; you adjust only the coin denomination.
- Objective: Align three identical symbols on a payline or trigger the Hold and Win bonus.
Triggering the Bonus Round
To start the Hold and Win bonus, you must land three scatter symbols in the central positions across the three reels. The game then switches to a separate bonus screen where those initial symbols lock in place and empty slots fill with volcanic coins.

Bonus Round and Volcano Jackpots
Once the bonus begins, you receive 3 initial respins. All coins and jackpots accumulated during Hold and Win get added to your total prize pool.
If you trigger the Ultra Bonus by landing three scatters inside the bonus, you’re awarded 5 respins and a guaranteed starting prize—often a significant multiplier up to 20× your bet. This can lead to cumulative payouts that regularly exceed 200×–300× your original stake.
The Grand jackpot pays 500× your bet. Although rare, landing the Grand jackpot can transform an entire session, recouping hundreds of spins’ worth of wagers in a single explosion of winnings.
Effective Game Strategy
- Budget Segmentation: Divide your bankroll into sessions of 100–150 spins to avoid depleting funds before hitting the bonus.
- Mid-Level Bets: Play average coin denominations to balance longevity with the chance of a big payout.
- Multiplier Tracking: Increase your bet slightly for the next 10–20 spins if Volcano multipliers appear frequently.
- Ultra Bonus Purchase: If available, compare the cost of the Buy Bonus feature to the average bonus win to decide if immediate entry is worthwhile.
- Take Breaks: Pause after 200 spins to avoid fatigue and maintain clear decision-making.
- Analyze RTP: Use demo mode to track the average return over 1,000+ spins, then compare with your live-session results.
