Avalon X Slot Overview
Merlin and Lancelot are off hunting the lost road to Avalon, and ELK has built the whole game around a single idea: wilds that swallow other wilds and come back stronger. Everything else feeds that.
The grid is a fixed 6x7 set inside a mossy stone arch. Wins come from clusters of five or more matching symbols joined up, down or sideways, and only the largest connected group of a type gets paid. Winning symbols blow up, survivors drop, fresh ones fill the gaps, and the chain keeps rolling while wins keep landing.
Then there is the sequel part. Avalon Gold was a ways game with a grid that stretched from four rows to eight and a ways count climbing toward 262,144. Avalon X throws all of that out. Fixed grid, clusters, hit rate lifted from 18% to 23.8%, ceiling cut from 25,000x to 10,000x. You hit more often and you can win a lot less.
Theme & Design
The grid sits inside a weathered stone arch with ivy spilling down the carved columns, a ruined staircase climbing off into green mist on one side and a waterfall stepping down wet rock on the other. Overgrown ruin rather than heroic quest, and it suits the material. The global multiplier hangs above the grid on a gold X-shaped plaque with a cracked red stone face in the middle, easily the loudest object in view and rightly so. Before the first drop there is a sword sunk into a mossy rock with light beams coming down through the trees, about as on-the-nose as Arthurian imagery gets, and then it is gone.
Symbols split into four knight helmets and four beast heads, colour-matched in pairs: green-plumed steel with a green serpent, crimson-and-gold armour with a red firebird, purple horns with a purple raven, dark blue steel with a blue wolf. Reading a cluster is easy because of that pairing. The trouble is that every symbol sits on a flat tinted tile, so a busy board looks closer to a match-three puzzle than to ancient Britain, and the teal-heavy palette lets the blue and purple tiles blur into each other when the grid fills up. The background is doing most of the atmospheric work.

Features & How They Work
Cluster wins and the global multiplier
Five or more identical symbols connected vertically or horizontally pay, and only the largest connected group of that type counts. Every winning cluster then pushes the multiplier above the grid: lows add 1, highs add 2. It opens at x1, applies to every cluster in the round, and never resets mid-round, so a long avalanche can leave the last clusters paying at x8 or x10 when the first ones paid at x1.
The payout curve matters more than the multiplier does. Payouts step in blocks rather than climbing symbol by symbol. The top helmet pays 1x for five, still only 2x for eight, then 5x for nine and 10x for anything from ten to twelve. A cluster of eight is almost nothing. A cluster of thirteen is 25x. That shape is the reason the rest of the game exists to inflate cluster size.
Wild Generation, Merge and Split
This is the part worth paying attention to. Every winning cluster leaves a wild behind: once the symbols explode, one wild drops into one of the holes they left. It does nothing for the win that just paid. It is stock for the next drop in the chain.
Wilds carry a value, and a plain wild counts as 1. When more than one wild sits inside the same winning cluster they merge, their values add up, and the wild that cluster generates carries the total. Two plain wilds produce an x2. That x2 landing later in a cluster alongside an x3 produces an x5. Values add rather than multiply, which stops it running away, but the ratchet only turns one direction and it turns across the whole avalanche chain.
Multiplier wilds apply to their own cluster before the global multiplier reaches it, so the two multipliers stack instead of competing. And a multiplier wild wedged between two separate winning clusters splits into both rather than counting for one. Deep chains are where the wild economy pays: three or four drops in, boards start carrying x4 and x5 wilds that arrived entirely on their own.
Big symbols up to 4x4
Every paying symbol and the Mystery Box come in four sizes: standard 1x1, Super 2x2, Mega 3x3 and Epic 4x4. A block counts as the number of squares it covers, so an Epic is sixteen symbols by itself, a paying cluster on arrival and straight into the top band. A dropping big symbol crushes ordinary symbols beneath it, sparing its own kind plus wilds, bonus symbols and Mystery Boxes, and any gap left under it fills with 1x1s of the same type. Given how steeply size is rewarded, big symbols are less decoration than the main engine for reaching the tiers that pay anything worthwhile.
Mystery Boxes and the Avalon features
Mystery Boxes drop on any column and block the space they take, paying nothing and getting in the way. They accumulate. Once five or more are in view and the avalanche has run out of wins, they all open, top to bottom, one column at a time. Big boxes shrink to 1x1 before revealing.
A box shows a paying symbol, a wild, or one of four Avalon features. Coin Win is a straight value multiplied by the bet. Collect sweeps every coin value already revealed into itself and then reactivates every opened box, so boxes that already paid pay again. Redrop awards an extra symbol drop plus guaranteed reactivation, and it always fires last, after everything else has resolved. Global Multiplier Spreader multiplies a random selection of the revealed coin values. If a reveal creates a win, the boxes return to blocking, the avalanche restarts, and they reopen once it ends.
Holy Strike
Holy Strike lands on any drop. It replaces a random set of symbols already in view with wilds, multiplier wilds or Mystery Boxes, leaving bonus symbols and anything already wild or boxed untouched. The count varies enormously, which is the point. Sometimes it is a handful of tiles. Sometimes it rewrites a chunk of the board and hands a dead drop a working cluster, or the two boxes it was short of.
Free drops, Super Bonus and X-iter
Three bonus symbols award 7 free drops, which is short, and ELK compensates by making things stick. The global multiplier carries between drops instead of resetting, and unopened Mystery Boxes stay on the grid, so a later drop can begin with the multiplier already in double figures and four boxes parked in the corners. Every extra bonus or super bonus symbol landing during the round adds 2 more drops.
One super bonus symbol with two regular ones starts the super bonus instead, and a super bonus symbol arriving mid-round upgrades a bonus already running. The difference is a guaranteed Holy Strike on every single free drop, and that is the version with any realistic path to the cap. X-iter prices it at 500x. Plain bonus entry is 100x, a guaranteed five-box drop is 50x, a guaranteed Holy Strike drop is 25x, and Bonus Hunt at 3x simply more than triples the trigger chance. The RTP is 94% whichever door you use.

How Avalon X Plays
Roughly a quarter of drops land something, and most of what they land is small. That is the texture of a session: the board is rarely quiet for long, and rarely loud either. Fives and sixes trickle in, the multiplier ticks up a step, the chain dies after an avalanche or two, and the balance drifts down anyway. Against a game paying 18% of the time it feels a good deal less punishing, but money moves slowly in both directions.
What you are really waiting on is the moment a chain refuses to die. Four drops deep the board is a different animal: wilds it manufactured itself, a multiplier in double figures, boxes stacking up in the corners. Those rounds are where the game finds some pull, and they are not common. The rest of the time the pull is the Mystery Box count, slow and visible, and honestly the best tension the base game has going. Three boxes sitting there needing two more is more interesting than most base games manage.
The bonus is short enough that it can finish before the persistence does anything for you. Seven drops with a carried multiplier sounds strong right up until a run of dead ones eats four of them. The gap between this game's flat rounds and its good ones is unusually wide, and at 94% you will spend a fair while in the flat ones.
Pros & Cons
Pros
- Wild Generation, Merge and Split builds a wild economy that is not a repaint of anyone else's
- 23.8% hit frequency keeps the base game from going dead for long stretches
- Big symbols up to 4x4 make oversized clusters realistic, and size is where the paytable pays
- Both the multiplier and unopened Mystery Boxes carry between free drops
Cons
- 94% RTP, the fourth ELK release running at exactly that number
- 7 free drops is short for a bonus built around persistence
- Only the super bonus threatens the top end, and X-iter prices it at 500x
- Symbols on flat tinted tiles read more like a puzzle game than ancient Britain
Is Avalon X Worth Playing?
The frame around this game is familiar, and the frame is what most people judge it on: cluster grid, avalanches, a global multiplier ticking +1 and +2, a five-tier buy menu, Mystery Boxes carried straight over from the first Avalon. Called unadventurous, that is fair enough. The wild system underneath it is not borrowed from anywhere obvious though, and a wild that inherits the summed value of the wilds that created it is a smarter idea than the shell wrapped around it. How much that counts depends on how much credit you give a good mechanic sitting inside a conventional game.
The sequel maths is the harder question. Trading 25,000x for 10,000x while lifting the hit rate to 23.8% looks like a downgrade written on the box, and for anyone who played Avalon Gold for the ceiling, it is one. It is also the more sensible build. At 94% there is only so much return to hand out, and a 25,000x tail parks a great deal of it somewhere almost nobody ever collects. Avalon X drags that back toward the middle, you feel the difference drop to drop, and the price is a top end that is unremarkable for a 2025 cluster release. The 94% is the part that is hardest to defend, four games deep into the same number.
