Avalon X RTP and Wagering

Avalon X - RTP and Wagering

Avalon X uses an extra-large 6x7 grid but does not have paylines like most other online slots. It uses the cluster pays system instead. You win by forming clusters of five or more identical symbols on the grid. To count as part of a cluster, symbols have to be touching horizontally or vertically.

The bet size options range from £0.20 to £5. The maximum payout you can win from Avalon X is 10,000x your bet. However, the slot’s RTP is only 94%, which is considerably lower than the average online slot RTP of 96%. ELK Studios, the slot’s provider, rates the volatility as 7/10, which is medium-high.

Avalon X Symbols and Audio & Video Design

Avalon X draws inspiration from Arthurian legend and focuses on the island of Avalon. This was where Excalibur, the legendary sword, came into existence, and where Arthur recovered after taking part in the Battle of Camlann and sustaining serious wounds. The reels are within an ornate ruin that stands in a beautiful, tranquil forest setting; accompanying the gameplay is a mysterious, atmospheric soundtrack.

There are eight regular paying symbols: four animal icons and four knights. Each of these, along with the mystery box symbol, can be 1x1, 2x2, 3x3 or 4x4 in size. The payouts for all the slot’s regular symbols are as follows.

Avalon X Mobile Features

Like other ELK Studios slots, Avalon X is playable on mobile devices, including both smartphones and tablets. It works the same on mobiles as it does on desktop computers and laptops. The interface is slightly different to better suit smaller devices, but other than that everything is pretty much the same. The slot looks great and plays well whether you access it through a browser-based site or casino app.

Avalon X Bonus Features

Avalanches, Wilds and the Global Multiplier

Whenever you win, an avalanche takes place. All winning symbols vanish, then a wild appears in one of the empty positions. Symbols then fall from above to fill in all empty spaces, which can create new winning clusters and trigger another avalanche. If there is more than one wild in a winning cluster, they merge to form a multiplier wild. 

The slot has a global multiplier that starts at 1x and grows during an avalanche sequence. Each cluster of low-paying animal symbols increases the global multiplier by 1x, while each cluster of high-paying knights increases it by 2x. It resets to 1x when an avalanche sequence ends.

Holy Strike

On any spin, the Holy Strike feature can trigger. When it does, it replaces a random number of symbols on the grid with wilds, multiplier wilds or mystery boxes.

Mystery Boxes

Pentagram symbols are mystery boxes. Whenever five or more of them are in view, each one of them reveals a reward. This can be one of the regular paying symbols, wilds or one of four Avalon features.

Avalon X - Mystery Boxes Freature

Avalon Features

The four Avalon features are:

  • Coin Win: The mystery box reveals a coin with a cash value. You then receive a payout equal to this value multiplied by your bet.
  • Collect: Collects the values on all coins, multiplies them by your bet and pays you the result. All mystery boxes with coins then reactivate.
  • Redrop: Once all other mystery boxes have opened, an avalanche takes place then all mystery boxes reactivate.
  • Global Multiplier Spreader: A multiplier applies to a random selection of coin symbol values.

Free Drops Bonus Game and Super Bonus Game

Land three scatters and you will earn seven free spins. While using these, the global multiplier does not reset in between spins and mystery boxes stay where they are until they open. If two scatters and a super scatter land, you get to play the Super Bonus Game, where Holy Strike triggers on every spin.

Avalon X Final Thoughts

Avalon X is a visually impressive slot with an interesting theme and more than enough gameplay features to make it worth a spin or two. With free spins, mystery boxes, extra-large symbols and multipliers, there is certainly a lot going on. The maximum win of 10,000x is pretty good, though the RTP of 94% lets the slot down a little bit. Having said that, Avalon X is still very much an enjoyable slot that should appeal to those who like feature-heavy online slots.
