Enjoy the glitz and glamour of Swintt’s ever-changing crystal dimension in the studio’s latest slot release, Crystalium, which has claimed Slot of the Week.
Crystalium is a changing reel size cluster slot with a maximum size of 7×7 and a maximum win of x5,547.8 the player’s stake. It has a medium to high volatility with an RTP of approximately 94.1%.
David Mann, Chief Executive Officer at Swintt, said: “The Swintt Elysium Studios’ line-up has continued to push the boundaries of what’s possible from a video slot, and Crystalium is another great example of us thinking outside the box.
“Featuring a never-before-seen shifting reels mechanic, the game consistently keeps players guessing and offers excitement on every spin as they chase cluster wins and attempt to trigger an infinitely rewarding bonus round.”


The title’s low-value symbols are purple, blue, green and red crystal balls. These symbols can offer x0.2 to x50 the player’s bet, depending on the combinations which land on the reels following a spin.
Purple, blue, green and red crystals are the game’s high-value symbols. Depending on which combinations are present on the reels, these symbols can offer x0.3 to x250 the player’s wager.
A white crystal with a W is the title’s wild symbol, which substitutes for all paying symbols.
Alongside the changing reel sizes, the game also has cloning wild scatters, a free spins mode, a bet boost and a buy feature.


Red, green or blue wild scatters can randomly land on the reels. They turn a wild into a clone of themselves on a random number of neighbouring positions in a straight line.
Blue scatters clone horizontally, green scatters clone vertically, while red scatters clone horizontally and vertically.
A free spins progress bar is next to the reels in the base game. The player is awarded eight free spins once the progress bar is filled. Changing reels and cloning wilds can occur during free spins.


When free spins are active, an infinite progress bar is displayed, with each cascade and respin unlocking a new section. These sections contain a multiplier that rises by two for each cascade and respin, with multipliers added to each subsequent win until a new multiplier is achieved.
The multiplier doesn’t reset until the free spins round has concluded, with some sections randomly awarding additional free spins.
The free spins mode can be purchased for x120 the player’s stake. There is also a bet boost which triples the chance of free spins mode being triggered for x0.4 the player’s bet.
