Opal Fruits Slot RTP, Details & Wager Limits

Reels/Paylines: 6 reels + 5,625 paylines

Stakes Range: 10p to £120 per spin

RTP: 96.67%

Max Win: 36,600 x stake per spin

The Opal Fruits slot comes with 6 reels, 3 rows and 5,625 ways to win. There’s an extra row above and below reels 2, 3, 4 and 5. The grid has a 3, 5, 5, 5, 5, 3 formation. You will see 6 reels with 3 rows with 2 rows above reels 2 through 5.

It uses a unique Triple Reaction game engine where there are extra rows below and above the reels. When a spin takes place, it spins in 3 different directions. Winning combinations are formed starting from the leftmost reel.

You can play Opal Fruits from as little as 10p up to £20 per spin. There’s a standard Auto Play function where you can opt for 5, 10, 25, 50 or 100 autospins. You can customise this by adding a loss limit or single win limits.

The Opal Fruits RTP is 96.67% which is quite high for an online slot. This gives the online casino just a 3.33% margin. Variance wise, this game is very high, so you’ll land smaller wins a lot more frequently.

The max win is 36,600 x your stake and this is best achieved during the free spins bonus feature due to the unlimited multipliers and free spins on offer.

Theme – Audio and Design Features – A retro space feel

Theme: Space

High Value Symbol: Grapes

Compatibility: Mobile, Tablet, Desktop


Visually, Opal Fruits has a retro feel to it and it’s set in outer space, Big Time Gaming’s CEO, Nik Robinson, said the slot is “somewhere between Daft Punk and a Commodore 64” visually.

With an 80s arcade feel, Big Time Gaming used original samples of Williams Electronics’ Robotron and Defender SFX to create the soundtrack, which is very cool if you’re a fan of 80s gaming.

The semi-transparent reels appear in a 3, 5, 5, 5, 5, 3 formation. Symbols on the reels include A, K, Q, J, 10 and 9 royals as well as pears, plums, watermelons and grapes. The grapes symbol is the most rewarding with 6 giving you 50 x your stake.

There’s a standard wild symbol that replaces all symbols bar the scatter. These only appear on the extra reels above and below the main reel set. There are also 3x wilds that trigger the Multiplier feature.

Opal Fruits Mobile


Despite the retro theme, Opal Fruits can be played on mobile and tablet devices as well as desktop as Big Time Gaming has produced it using HTML5 technology. It runs smoothly on smaller screens with sharp HD graphics accompanying the retro soundtrack.

Opal Fruits Bonus Features

The Opal Fruits slot game comes with 3 bonus features. In the base game, you will see 3x multipliers that can combine to give you a 1,296x multiplier. In the Free Spins feature, you can get infinite free spins and see the multiplier increase with no limits.

Reactions feature

When you get a winning combination, the Reactions feature comes into play. Winning symbols disappear and are replaced with new symbols. This gives you the chance to win again and again on every spin.

Wild Multipliers feature

Look out for the 3x wild symbol which triples your outcome when part of a winning combination. They only appear in the base game and on the extra reels. If you get more than one landing simultaneously, they multiply each other when appearing on different columns.

For example, if they appear on the same column, they will be added together meaning a potential 6x wild multiplier per reel. If all 3x wild symbols land perfectly, you could benefit from a huge 1,296x wild multiplier:

6 x 6 x 6 x 6 = 1,296x wild multiplier

Free Spins feature


The Opal Fruits slot game focuses on the Free Spins feature. This is triggered when you spell the word F-R-E-E in gold scatters. This will give you 10 free spins. Triggering the feature with extra scatters sees you begin with a higher multiplier:

4 scatters 10 free spins with 1x multiplier
5 scatters 10 free spins with 5x multiplier
6 scatters 10 free spins with 10x multiplier

Every winning combination increases the multiplier by 1. There are no limits to how high the multiplier can go. Once you reach a multiplier of 10 (i.e. 10x, 20x and so on), you’ll be rewarded with 5 additional free spins. Again, there are no limits to how many free spins you can play with.

RTP (96.67%)

Max Win (36,600 x)


The Opal Fruits slot is another great game from Big Time Gaming which is innovative and can provide huge wins of 36,600 times your stake on each free spin.

You can win big in the base game with the potential 1,296x multiplier but the max wins will come in the Free Spins feature due to the unlimited multiplier.

Opal Fruits arguably blows slots like NetEnt’s Starburst out of the water. It also shows that Big Time Gaming is not just relying on its popular Megaways slots and will release innovative concepts that offer something unique to players. Overall, a superb, high variance slot.

This game is described as Big Time Gaming’s Nik Robinson as the successor to Bonanza Megaways. It’s definitely different and presents a new, albeit volatile, challenge for slot players.

  • 36,600 x max win
  • RTP well above average
  • Unlimited free spins and multipliers
  • Low value symbols
