Lava Burst by Evoplay on 1xBet

Lava Burst is an Evoplay slot built around a twelve-cell Bonus Game and four fixed jackpots. The recorded specification lists RTP at 96.27% and volatility as high. Availability of a title can still vary by region or account.
Base game and the central-line trigger
Ordinary base play produces Bonus Coins, Heavy Coins and Mystic Symbols. Four symbols landing on the central line start the bonus with three spins. Every new Bonus symbol that appears restores three spins to the counter.
What Bonus Coins and Heavy Coins are worth
Bonus Coins pay only during the Bonus or Ultra Bonus Game. Their values differ by coin type, and one type also has a persistence rule tied to the stake.
| Symbol | Value range | Behaviour |
|---|---|---|
| Ordinary Bonus Coin | 1x to 4x bet | Pays within the Bonus or Ultra Bonus Game |
| Heavy Coin | 5x to 9x bet | Stays until bonus entry; changing the bet removes it |
| Mystic Jackpot | Mini, Minor or Major | Guarantees one of those three jackpots |
Mystic Symbols and the Black Hole
Mystic Symbols transform when the Bonus or Ultra Bonus Game ends. The product sheet excludes the Heavy Coin outcome from that transformation. A Black Hole collects all Bonus values and jackpots that landed before it during a bonus.
Lava Burst comets and growing multipliers
The Lava Burst feature can ignite at any moment in the Bonus or Ultra Bonus Game. It sends one to twelve fire comets into random cells. Each struck cell starts at an x2 multiplier, and a cell hit again increases by one.
How the twelve-cell bonus reaches its end
The bonus uses twelve positions and stops either when the spin counter expires or when every position is filled. Filling all twelve awards the Grand jackpot. The source also describes gathering all twelve Bonus symbols of any type to reach Grand.
Evoplay product details
The developer's widget shows a maximum win of €706,425 under its default-bet assumptions. That figure belongs to the widget's own setup rather than to every possible configuration.
| Jackpot | Value in bet terms | How it is reached |
|---|---|---|
| Mini | 25x bet | Through a Mystic Jackpot symbol or from the transformed Mystic Symbols |
| Minor | 50x bet | Same Mystic routes |
| Major | 100x bet | Same Mystic routes |
| Grand | 1000x bet | Filling all twelve positions |
Bonus and Ultra Bonus compared
Both bonus forms share the twelve-cell board, the coin values and the Mystic transformation. The distinction lies in how early and how often Lava Burst comets arrive.
| Feature | Bonus Game | Ultra Bonus Game |
|---|---|---|
| Entry trigger | Four symbols on the central line | Not separately stated in the product sheet |
| Initial spins | 3 | Not separately stated in the product sheet |
| Spin restoration | New Bonus symbols restore 3 spins | Not separately stated in the product sheet |
| Lava Burst | Can ignite at any moment | Starts with Lava Burst and triggers it more often |
| Board | 12 cells | 12 cells |
Reading the feature order
The productive sequence starts with a central-line trigger, then uses landed coins and Mystic Symbols as stored value. Lava Burst comets add multipliers on top of that stored value. The Black Hole consolidates what has already appeared, and the twelve-cell completion pays Grand.
- Central-line four symbols open the bonus with three spins.
- Bonus Coins carry 1x to 4x bet and Heavy Coins 5x to 9x bet.
- Mystic Symbols transform at the end of the bonus, excluding Heavy Coin.
- Mystic Jackpot guarantees Mini, Minor or Major.
- Black Hole collects earlier Bonus values and jackpots.
- Lava Burst comets strike 1 to 12 random cells.
- Repeated comet hits raise a cell's multiplier by one.
- Grand is awarded when all twelve positions fill.
Controls worth knowing before you play
Evoplay's demo runs the same documented controls as the live game, letting you set the bet and start spins without staking real funds. Changing the bet removes Heavy Coins that are waiting for bonus entry, so the stake should be settled before those coins appear.
The 1xBet catalogue page for Lava Burst uses the same Evoplay specification. Account-level configuration can still differ from the developer's default values. The primary source remains the Evoplay Lava Burst page.
