Crystal Caverns Megaways Slot by Pragmatic Play

For 80x your bet, the buy option drops you straight into the free spins round. That's where Crystal Caverns actually separates from base game play - the multiplier that ticks up with each tumble win stops resetting. In the base game, you get the same escalating multiplier (starts at 1x, climbs by 1 per tumble), but it zeros out once the tumble chain ends. During free spins, it carries from spin to spin for the entire round. A dozen consecutive dead spins don't touch it. Land a win on spin 15 and whatever multiplier you built on spin 3 is still there, still climbing.

The expanding wild mechanic is the other piece worth understanding. Wilds appear on reels 2 through 6 and on the independent top row that spins right-to-left above reels 2-5. When a wild hits anywhere except that top row, it stretches to fill the entire reel vertically. On a spin where reels 2-5 are showing 7 or 8 symbols each, one expanding wild covers a lot of real estate. Two expanding wilds on adjacent reels during a high-symbol spin, combined with a multiplier that's been building for six or seven tumbles - that's where the 10,000x ceiling comes into reach. The top row wilds don't expand, so they connect wins horizontally without the vertical coverage.

Glowing blue and purple crystal formations line both sides of the grid, with thick golden borders holding the reels in place against the dark cavern backdrop. Gem symbols - red, pink, purple, teal, gold - sit in ornate circular settings that catch light differently depending on their position. The colour palette stays cold throughout, all icy blues and deep teals, which makes the gold Megaways counter in the corner pop. Four scatters start the bonus at 12 spins, five at 16, six at 20 plus a 100x scatter pay. Retriggers add 5 spins each time 3 or more scatters land during the round. Elemental Gems Megaways runs a similar grid with the same engine, but Crystal Caverns leans harder on the expanding wild interaction - that single mechanic changes how the tumble chains build compared to a standard Megaways setup.
