The Mount Magmas slot is a 2021 Push Gaming game on five reels and four rows with 20 fixed paylines, a 96.5% RTP and medium volatility. Instead of free spins, it builds towards a Volcano Bonus: a Magma Spin that sets the prize range, then a pick game where you climb up to 11 levels of tiles until a pick comes up empty.
Magma Rocks fly to the volcano and leave a Wild Lava behind, and they can start the Volcano Bonus.
The bonus opens with a Magma Spin that sets the prize range and can award a jackpot.
A pick game follows, climbing up to 11 levels until a pick reveals no prize; there are no free spins.
At 96.5% RTP, the expected cost is about £3.50 for every £100 staked.

Push Gaming, the studio behind Mount Magmas
Push Gaming was founded in 2010 and is based in London, with an office in Malta. LeoVegas Group announced a majority stake in May 2023, which places the studio within MGM Resorts. Its British licence is Gambling Commission account 054984, held by Push Gaming Holding Limited.
The studio is best known for Jammin’ Jars, Razor Shark and Big Bamboo, which are all rated high volatility, and we also review the sequel Jammin’ Jars 2. Mount Magmas is a gentler, medium-volatility title by comparison.
How the features work
Wild Lava
The Wild Lava symbol substitutes for every symbol except the Magma Rock. It helps complete lines across the 20 paylines like a standard wild.
Magma Rocks
When a Magma Rock lands, it flies off to the volcano and leaves a Wild Lava in the spot it came from. So each rock adds a wild to the reels for that spin, and the rocks heading to the volcano can also set off the Volcano Bonus.
The Volcano Bonus: Magma Spin
The bonus begins with a Magma Spin. This sets the range of prizes available in the next stage, and it can also award a jackpot outright.
The Volcano Bonus: the pick game
Next comes a pick game. You choose tiles and climb level by level, up to 11 levels in total. The round continues until one of your picks reveals no prize, at which point the bonus ends and your total is paid.
Mount Magmas has no free spins. All the bonus value sits in the Magma Spin and the pick game. Exact jackpot and prize values are listed in the game’s paytable.
A pick bonus instead of free spins: what changes
In a free spins round, the outcome depends on reels spinning a set number of times. In Mount Magmas, the bonus is decided by the Magma Spin’s prize range and how far up the levels you get before an empty pick.
Your choice of tile can feel like a skill, but the outcomes are set by the game’s random number generator and its design. Picking a particular spot doesn’t change the expected return. Our RNG explainer covers how results are decided.
On a phone, a pick game is easy to play with taps, and it doesn’t need the fine reel detail that some slots do.
Mount Magmas RTP: a £20 budget at 10p, 50p and £1
An RTP of 96.5% means a long-run house edge of 3.5%. That works out at about £3.50 lost per £100 staked across a very large number of spins. Use it as a measure of cost, not a prediction.

The hourly column is stake × 600 × 3.5%, which assumes about one spin every six seconds. Medium volatility tends to give more regular, smaller wins than high-volatility games, which can make a £20 budget last longer at 10p. Over time, losses are still the likely outcome. The house edge glossary entry explains why.
Playing the Mount Magmas slot on your phone
Push Gaming builds its games in HTML5, so Mount Magmas runs in casino apps and phone browsers on iPhone and Android. A 5×4 grid fits comfortably on most screens, and the pick game suits a touchscreen.
Install a UK-licensed casino app from the App Store or Google Play, or open the casino’s mobile site.
Complete the age and identity checks that UK rules require before any play.
Set a deposit limit at the prompt before your first deposit.
Find Mount Magmas in the game lobby and open its help screen to check the RTP, jackpot values and maximum win.
Set your stake and spin manually; when the Volcano Bonus starts, tap tiles to make your picks.
Online slot stakes are capped at £5 a spin for players aged 25 and over, from 9 April 2025, and at £2 for those aged 18–24, from 21 May 2025. The Gambling Commission’s stake-limit guidance (opens in a new tab) defines a game cycle as running until all winnings are made available, so the Volcano Bonus forms part of the spin that triggered it.
Since 31 October 2021, slots must have no autoplay, a minimum of 2.5 seconds per spin, no turbo or slam-stop, and no celebration of a return at or below the stake. The Commission’s RTS 14 standard (opens in a new tab) notes that the speed rule doesn’t apply to bonus features where no extra stake is wagered.
Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players. Read our summaries of slot stake limits and the autoplay ban.

Frequently asked questions
What is the RTP of Mount Magmas?
Mount Magmas has an RTP of 96.5%, which means a house edge of 3.5%. Over a very long run that averages about £3.50 lost per £100 staked, but a single session can come out well above or below. Confirm the figure in the game’s help screen in your app. Our guide on how to find the RTP in a casino app explains where to look.
Does Mount Magmas have free spins?
No, Mount Magmas has no free spins round. Its bonus is the Volcano Bonus, which starts with a Magma Spin that sets the prize range and can award a jackpot, followed by a pick game of up to 11 levels. The pick game ends when a pick reveals no prize. For how bonus rounds compare with free spins offers, see free spins in casino apps.
How do you trigger the Volcano Bonus in Mount Magmas?
The Volcano Bonus is triggered through Magma Rocks. When a Magma Rock lands, it flies to the volcano and leaves a Wild Lava in its place, and these rocks can set off the bonus. The exact trigger condition is described in the game’s paytable, so check there in your app. Our slots on mobile guide covers how bonus triggers work generally.
What does the Wild Lava symbol do?
Wild Lava substitutes for every symbol except the Magma Rock, helping to complete wins on the 20 fixed paylines. A Wild Lava also appears wherever a Magma Rock lands, because the rock leaves one behind when it flies to the volcano. That means Magma Rocks add wilds to the reels as well as building towards the bonus. The paytable glossary entry explains how to read symbol rules.
Does picking tiles in Mount Magmas involve skill?
No, the pick game doesn’t involve skill. Although you choose the tiles, the results are set by the game’s random number generator and its design, so no choice changes the expected return. Picking quickly or slowly makes no difference either. The bonus ends when a pick reveals no prize. Our RNG games guide explains how random outcomes work.
What is the max win on Mount Magmas?
We haven’t been able to verify a maximum win figure for Mount Magmas, so we don’t quote one. The game can award a jackpot through the Magma Spin, and the jackpot and prize values are listed in the paytable. Open the game’s help screen in your casino app to see the cap. Our house edge by game page puts slot costs in context.
Is Mount Magmas good for beginners?
Mount Magmas suits beginners well because it’s medium volatility with 20 fixed lines and a simple pick bonus. Medium volatility tends to give more regular, smaller wins than high-volatility games, which can make a small budget last longer. It still carries a house edge, so expect to lose over time. Our best casino apps for beginners list may help you choose an app.
Can I play Mount Magmas on mobile?
Yes, Mount Magmas runs on iPhone and Android in casino apps and mobile browsers, because Push Gaming builds its games in HTML5. The 5×4 grid fits most phone screens, and the pick game is easy to play with taps. Availability depends on your casino’s lobby. See our Android phones guide for installing UK casino apps.
