3 Super Coin Volcanoes slot: Hold and Win, four volcanoes and the Super Wheel

3 Oaks Gaming's January 2026 sequel to 3 Coin Volcanoes: a small 4x3 grid, a Hold and Win bonus with four jackpots and volcano upgrades.

By Eleanor Hartley, editor · Checked on 2 November 2026

3 Super Coin Volcanoes is a 3 Oaks Gaming slot released in January 2026 as the follow-up to 3 Coin Volcanoes. It runs on a compact 4-reel, 3-row grid with just 3 lines, and almost everything that matters happens in its Hold and Win bonus, where volcano upgrades can change the grid, the respins and the multipliers. The listed top win is 2,000x the stake.

A sequel, not a reskin of 3 Coin Volcanoes

The name is close to the original, but the 3 Super Coin Volcanoes slot is a separate game with its own maths. The return figure differs from the first title, so numbers quoted for 3 Coin Volcanoes do not carry over. The one RTP figure available for this sequel is 95.70%, from a third-party source; 3 Oaks does not publish RTP on its own site. Treat it as a guide and confirm it in the game's information screen before you play, since the build a casino runs is what counts. The RTP guide explains why two casinos can show different returns for the same title.

How the Hold and Win bonus starts

The bonus triggers when 4 Bonus symbols land on an active line. Inside it, coin values lock in place and respins reset when new symbols arrive. Alongside ordinary coins you can see Mini, Minor and Major jackpot symbols, plus Mystery, Mystery Jackpot and Collect symbols, which reveal or gather values. Filling every position on the grid awards the Grand Jackpot.

Four volcanoes and the Super Wheel

The volcanoes are the sequel's main addition, and the Super Wheel is what switches the enhanced mechanics on:

• The Super Wheel unlocks the enhanced bonus mechanics.
• Gold Volcano brings upgraded x5 multipliers.
• Life Volcano replenishes respins, extending the round.
• Multi Volcano applies up to six 2x multipliers.
• Grow Volcano adds two rows, so the grid becomes larger.

If the enlarged grid is filled completely, the game awards a Royal Jackpot on top of the standard Grand.

What you can stake in Great Britain

The bet range listed for the game runs from £0.10 to £40, but that upper figure does not apply to players in Great Britain. Since 9 April 2025, online slots here have a maximum stake of £5 per game cycle, and since 21 May 2025 the cap is £2 for customers aged 18 to 24. A licensed casino sets the game's limits to match. The slot stake limits guide covers the rules in full.

Trying the 3 Super Coin Volcanoes demo

There is no playable version on this page. A 3 Super Coin Volcanoes demo, where one exists, sits on the provider's own site or in the lobby of a licensed casino in demo mode. Under Gambling Commission rules, a GB-licensed casino must verify your age and identity before you can use free-to-play versions of its games, so expect to complete those checks first. The online slots hub lists other games reviewed here.
