Crystal Forest Slot by Light & Wonder

The unusual thing first: there is no scatter symbol. None. Free plays in Crystal Forest are triggered purely by chaining cascades on a single spin, which is a mechanic Light & Wonder still hasn't really copied onto anything else in their classic catalogue. Win, watch the symbols vanish, new ones drop from above, win again, repeat. Get four consecutive cascades on one spin and you have 7 free plays. Five cascades pays 10, six pays 15, seven pays 25, and if you somehow manage eight or more cascades on a single spin the game hands you 50. No scatter chase, no key symbols to collect, just keep the chain alive.

There is a second way in, and it's an honest little surprise: at the end of any base spin that didn't already trigger the bonus, the game can randomly award 7 free plays out of nowhere. It does not happen often, but it's a real mechanic and not a marketing line.

The base reels run a fairly standard premium ladder. A glowing winged fairy with brunette hair sits at the top, then a red-roofed lantern, a stack of red-capped toadstools, a stargazer lily bouquet, a blue potion bottle, a crystal wand, and a white rabbit curled up in the moss. The art is painterly storybook fantasy, deep moonlit blues behind a twisted-vine border crusted with violet crystals. Calm, not loud. The wild is a full-reel gold-framed tile reading "WILD" over a forest stream illustration, and it only lands on reels 2, 3, 4 and 5. Reel 1 never gets one, which matters when you're hunting that fairy premium from the left.

In the free plays round the reel strips shift to favour more of those stacked wild blocks, and the retrigger rule is the same engine as the base trigger: four or more consecutive cascades on a single free play adds extra plays on top of whatever you have left. The cash ceiling is a hard 250,000-credit cap.
