Mount Magmas slot

How the Mount Magmas slot machine works

Mount Magmas comes from Push Gaming, the studio behind Razor Shark and Jammin’ Jars. The base game is a familiar line slot: five reels, four rows and 20 paylines that are always active. What sets it apart is the volcano beside the reels, which fills with Magma Rocks and can erupt into a bonus game.

1. Choose your stake; it covers all 20 lines.
2. Spin. The RNG fixes where each reel stops before any animation plays.
3. Line wins are paid from the leftmost reel, with lava stone wilds helping to complete them.
4. Any Magma Rock that lands is collected into the volcano and replaced by a wild on the reels.
5. Each collection has a random chance to trigger the Volcano bonus.
6. If the bonus triggers, a Magma Spin sets its top prize, then the pick game begins.

Because the rock turns into a wild after being collected, it does two jobs: feeding the meter and helping the current spin. The random number generator decides both the rock landing and whether a collection triggers the bonus.

Crystals, lava wilds and stacked symbols

The symbols are gemstones and crystals in different colours, with a red crystal at the top of the paytable. Game databases describe the premium crystals as able to land super stacked, filling whole reels, which is how the biggest base-game line wins form. A stacked symbol covering a whole reel counts on every line that passes through it.

If gemstones as slot symbols interest you, our page on gem symbols traces how they replaced fruit on many modern games. The wild symbol works in the usual way, standing in for paying symbols on a line.

The Mount Magmas bonus: Magma Spin and Volcano pick game

The bonus has two stages. First a Magma Spin sets the prize at the top of the volcano, which game databases describe as either a large multiplier or a jackpot prize, depending on the version. Then the Volcano bonus begins: a pick me bonus laid out as rows of tiles climbing up the mountain.

Each pick reveals a cash prize, a level-up to the next row, or a game over. Reaching higher rows opens bigger prizes, and the top tier holds the prize set by the Magma Spin. Your choices feel like decisions, but the prize map is set by the game’s maths; there is no tile-picking skill that improves the return.

Jackpot amounts and the exact prize range depend on the version your casino runs. Read the help screen rather than relying on figures quoted elsewhere.

Does Mount Magmas have free spins?

No. Mount Magmas has no free spins feature. All of its bonus value comes from the Volcano pick game and the wilds left behind by Magma Rocks. That is unusual: most modern video slots put the bulk of their return in a free spins round. It also means the game can feel steadier, since there is no long wait for scatters, but the bonus trigger itself is random and unpredictable.

If a casino advertises free spins ‘on Mount Magmas’, that is a promotion with its own terms, not a game feature. And as with every slot supplied to Great Britain, there is no option to buy the bonus; see our page on bonus buy in the UK.

Mount Magmas RTP and volatility in pounds

At 96.5% RTP, the house edge is 3.5%. The volatility is rated medium, which matches a design where wilds appear regularly and the bonus pays through picks rather than long free spins chains.

Push Gaming supplies some of its games in lower-RTP versions as well, so confirm the figure in the rules screen. A hypothetical 94.5% version would raise the house edge from 3.5% to 5.5%, making each spin about 57% more expensive on average, which adds up over long sessions. Our RTP variants page explains why.

Mount Magmas max win and UK stake limits

We don’t list a Mount Magmas max win because no figure is in our verified records for this game. The help screen in your version states the cap, and the top Volcano tier, including any jackpot prize, is described there as well. Our guide to max win caps explains how to read these limits.

Whatever the cap, it scales with your stake. The table shows what an illustrative win of 1,000 times the stake would be worth at each UK stake level. It is not a figure for this slot.

The £5 and £2 limits are explained in the Gambling Commission’s online slots stake limit guidance (opens in a new tab) and on our stake limits page.

Mount Magmas vs other Push Gaming slots

Mount Magmas is the medium-volatility option in this group, sharing its 5 × 4, 20-line frame with Razor Shark. Big Bamboo and Fat Rabbit are much more volatile. If you like the pick-game idea, our bonus features guide compares picks, wheels and free spins.

Mount Magmas myths: is the volcano ever ‘ready to blow’?

• ‘A full-looking volcano means the bonus is close.’ Each Magma Rock collection has its own random chance to trigger the bonus. The volcano picture is a display, not a countdown.
• ‘Picking the left-hand tiles pays more.’ Tile positions carry no advantage; outcomes are set by the game’s maths.
• ‘Medium volatility means I’ll get my money back.’ No. The house edge still applies, and losses over time are the expected outcome.
• ‘Quiet spells mean the slot is tight today.’ The RTP is fixed in the version; there is no daily setting. See loose and tight slot machines.

Is Mount Magmas worth playing? Who it suits

Mount Magmas suits adults who like a steady line game with a separate bonus and are curious about a pick format. If you specifically want free spins, games such as Pharaoh’s Fortune put their value there instead.
