Crystal Cavern Megaways Slot RTP, Details & Wager Limits

Reels/Paylines: 6 reels + up to 200,704

Stakes Range: 20p to £100 per spin

RTP: 96.46%

Max Win: 10,000 x stake per spin

The Crystal Cavern Megaways slot uses the Megaways engine from Big Time Gaming. With 6 reels, there’s up to 200,704 ways to win. On each spin, each reel can contain a random number of symbols. The more symbols per reel, the more Megaways. A win is formed when 3 or more matching symbols appear on consecutive reels beginning from reel 1.

With stakes ranging from 20p to £100 a spin, there are plus and minus buttons below the reels which allows you to adjust according to your pocket. In some countries, you will find an Autoplay function as well as Quick Spin and Turbo Spin modes.

The Crystal Cavern Megaways RTP is 96.46% which is normal for a Pragmatic Play slot but higher than the 96% slots average return rate. Highly volatile and ranked 5/5 by the developer, big wins will be hard to come by.

The maximum win per spin or free spin is 10,000 x your total stake. Your chances increase in the Free Spins feature due to the increasing and unlimited win multiplier.

Theme – Audio and Design Features – Da Vinci Diamonds meets a frozen cave

Theme: Crystal

High Value Symbol: Red Crystal

Compatibility: Mobile, Tablet, Desktop


With a crystal theme, the Crystal Cavern Megaways slot is set in a crystal-filled cave. It reminds me a little of IGT’s Da Vinci Diamonds with a frozen twist. The setting could be from Disney’s Frozen movie. With blue dominating the colour-scheme, the soundtrack is mystical yet gentle.

Symbols on the reels include A, K, Q and J royals as well as 5 different coloured crystals. The red crystal is the most lucrative symbol giving you 1, 2, 5 or 25 x your total stake for 3, 4, 5 or 6 in combination.

You also have a wild that substitutes for all symbols bar the scatter. It appears on all reels bar reel 1. That scatter is a white crystal with 4 or more triggering the free spins.

Crystal Cavern Megaways Mobile


With Pragmatic Play using HTML5 technology for all their slots, Crystal Cavern Megaways is no different. This means it’s available to play on mobile, tablet, laptop and PC devices. For the optimal experience, a larger screen such as a laptop or PC is recommended.

Crystal Cavern Megaways Bonus Features

The Crystal Cavern Megaways slot has 4 bonus features. With tumbles and increasing multipliers, there are expanding wilds in the base game. This all applies in the Free Spins feature with the multiplier only increasing.

Tumble feature

When you land a winning combination, the Tumble feature applies. Winning symbols disappear and the remaining symbols fall into the vacated spaces. New symbols then occupy the newly-vacated spaces to give you another chance of forming a win.

Importantly and unusually, the multiplier increases by 1 with each tumble. The multiplier increase and tumbles continue until no more new winning combinations are created.

Expanding Wild feature

Look out for the wild symbol landing in the base game or free spins. When a wild lands, it will expand to take over the whole reel. Called the Expanding Wild feature, you can benefit from up to 5 wild reels on each spin/free spin.

Free Spins feature


The Free Spins feature is activated when 4 or more white crystal scatters appear anywhere on the reels. 4, 5 or 6 scatters will pay 5, 10 or 100 x your total stake as well as 12, 16 or 20 free spins respectively.

Beginning with a 1x multiplier, every tumble/win increases the multiplier by 1. The multiplier doesn’t reset between free spins meaning it can only grow, infinitely. Land 3 or more scatters to win 5 more free spins, again with no limits. Finally, expanding wilds can come into play.

In some territories, there’s a Buy Free Spins feature. This allows you to buy your way into the Free Spins feature for 80 x your total stake. The RTP rate increases slightly to 96.47% too.

Crystal Cavern Megaways Review Summary – classic Megaways action

Sounds & Music

Bonus Features

RTP (96.47%)

Max Win (10,000 x)


The Crystal Cavern Megaways slot looks great and is a bit of a mashup between Da Vinci Diamonds and Play ‘n GO’s Frozen Gems. The theme/visuals will appeal to players who have played slots popular in Las Vegas. It has a very classic feel graphically.

In terms of gameplay, it offers nothing unique or revolutionary for a Megaways game. However, an increasing multiplier in the base game is unusual but welcome. With expanding wilds also on offer, Crystal Cavern Megaways offers a higher chance of landing the max win (10,000 x stake) on a base game spin compared to other Megaways slots. These extras are also available in the Free Spins feature where the multiplier doesn’t reset.

Overall, Crystal Cavern Megaways is a decent Megaways production which looks good, has all the standard elements with a couple of twists thrown in, a high RTP rate and good max win potential.

If you want a frozen adventure, 90k Yeti Gigablox from 4ThePlayer is recommended. Set up Mount Everest, it comes with huge Gigablox symbols up to 6×6 in size. With random base game features and free spins, you can win up to 90,000 x your total stake on each spin/free spin.

  • 10,000 x stake max wins
  • Expanding wilds + increasing multiplier in base game
  • Higher than average RTP (96.47%)
  • Nothing unique (classic Megaways features)
