Merlin’s Millions Slot RTP, Details & Wager Limits

The Merlin’s Millions slot is played on 5 reels, 4 rows and 50 fixed paylines. To create a winning combination, land 3 or more matching symbols or wilds on a payline, starting from reel 1.

Stake levels here range from between 50p and £125 per spin. The max stake can go up to £875 per spin if you use the SuperBet feature (more info below). Activate autoplay and you’ll have the option to run up to 100 autospins if required. Use the slider to set the required number of spins.

The Merlin’s Millions RTP is 95.08% which is a little on the low side. However, it you activate the SuperBet feature, the RTP increases to 95.63%. What certainly isn’t below average is this game’s variance. The volatility is extremely high. As a result, the max win is 1,000 x your total stake per spin. With the SuperBet feature, the max win is 10,000 x your total stake.

Theme – Audio & Design Features – join the wizard in his forest hideaway


Based on the Great Wizard of Arthurian Legend (Merlin), there’s a cartoonish feel to the design in the Merlin’s Millions slot. This game first hit the online casino shelves in 2012 so the visuals aren’t quite as sharp as you might expect to see compared to the latest slots, even if playing the HD version.

It’s still a bright colourful game though and the imagery is decent enough. There’s a fantasy-style soundtrack playing in the background which is a good fit for the Arthurian legend theme. It’s not the best-looking slot we’ve played but does the job.

An enchanting woodland is the setting here. Joining the lower value A to 9 royals on the reels are 3 higher value symbols. In order of value are the bottle of potion, magical staff and book of spells. The book of spells is the highest value symbol with 3, 4 or 5 across a payline paying 0.5, 2 or 20 x your total stake.

Merlin is the game’s wild. He appears as stacked on reels 2, 3 and 4 and substitutes for all other symbols apart from the owl and orb. Merlin is also central to the SuperBet feature which can boost your wild wins with some impressive multipliers, for a price. We’ll look at this in detail below. There are also 2 scatters, the shimmering orb and the owl, both of which can trigger a feature.

Merlin’s Millions is available to play on all devices including smartphones. The simple features and bold visuals are a decent combination if you’re playing on a small screen.

Merlin’s Millions Bonus Features

There are some classic features on offer in the Merlin’s Millions SuperBet slot. Highlights include stacked wilds, a pick and click bonus and free spins with added wilds. There’s also the SuperBet feature which can bring more winning opportunities into play, at a cost.

SuperBet feature


The first decision you’ll have to make when firing up Merlin’s Millions is whether to activate the SuperBet feature. This is an additional wager that brings multipliers into play when you make up a winning combination that includes Merlin the wild.

The price of each spin varies depending on how big the wild multipliers are. Furthermore, the RTP increases to 95.63%. We look at the stakes per level based on a £1 spin price:

Level SuperBet Stake SuperBet Multiplier Max Win Per Spin
1 2 x original stake 2x wild multiplier 2,000 x stake
2 3 x original stake 4x wild multiplier 4,000 x stake
3 5 x original stake 6x wild multiplier 6,000 x stake
4 6 x original stake 8x wild multiplier 8,000 x stake
5 7 x original stake 10x wild multiplier 10,000 x stake

To activate the SuperBet feature, click on the SuperBet icon in the bottom right-hand corner of the screen and pick your level. If you played at SuperBet level 5 and had a win with the Merlin wild symbol, a 10x multiplier would be applied to your winnings.

As a result, the max win per spin varies depending on your chosen SuperBet level. Playing at Level 5, you can win up to 10,000 x your total stake per spin as opposed to 1,000 x stake when switched off.

Free Games feature

Landing 3 orb scatter symbols anywhere on the reels on the same spin triggers the Free Games feature. Here you can look forward to 5 free spins.

An animated Merlin appears to the side of the reels. On each free spin, Merlin will conjure up a spell which turns random symbols into wild. A retrigger is possible here too meaning up to 10 free spins in total. If you have the SuperBet feature active, a multiplier up to 10x will be applied to winning combinations involving the Merlin wild symbol.

Owl Bonus feature

The Owl Bonus feature is activated by landing 3 owl scatter symbols on the same spin and in any position in the base game or during the Free Games feature.

In this pick ’em round, you’ll be offered a selection of owls to choose from. Pick owls to reveal cash prizes then keep on picking until you uncover the collect.

Merlin’s Millions Review Summary – all about the SuperBet feature

Despite its veteran status, the Merlin’s Millions slot remains a very popular game. The features are decent enough with the pick me round and free spins with added wilds offering some solid potential.

It’s the SuperBet feature which is the really intriguing aspect. If you want the maximum 10x wild multipliers, you would need to play at a minimum of £3.50 per spin which is expensive. However, the max win can range from 1,000 x stake per spin (with SuperBet off) up to 10,000 x your total stake per spin (at SuperBet Level 5).

How much risk you want to take depends on you. You need to take care  though as the volatility here is extremely high. If the master magician conjures up a spell, Merlin’s Millions SuperBet can deliver some exciting action.

If you want wild multipliers, the 300 Shields slot (by NextGen Gaming) offers the possibility of 300x wild multipliers in the free spins. Another good option if you like multipliers is Jammin’ Jars by Push Gaming where it can only increase in the free spins for potential wins of 20,000 x stake.
