Dragon Spin Slot by Light & Wonder

Three Bonus medallions on reels 2, 3 and 4 award one spin of a wheel, and that single wheel spin picks which of three completely different free-game rounds you drop into. You don't choose. The wheel does. Each variant runs five spins on a separate bonus reel set, none of them retrigger, and the three rounds are shaped so differently that the wheel result is effectively a variance decision baked into one button press.

Raining Wilds is the even-distribution option. Every spin, three to ten random wilds drop onto the bonus reels before evaluation, so all five spins carry roughly the same wild pressure and the round pays in flat, repeated bursts. Persisting Wilds is the late-payoff sibling, and the math is back-loaded on purpose: spins 1 through 3 land only 1-2 sticky wilds each, spin 4 widens to 1-3, and the final spin dumps 2-7 fresh wilds on top of everything that already locked. The whole round is built so the fifth spin is the one that matters. Reel Blast is the horizontal-coverage variant. Three reel sets play at once but share a single center reel spanning columns 2, 3 and 4, so whatever symbol resolves on that shared center counts for every set above and below it. Effectively 9 reels of simultaneous payline action per spin, with line wins multiplied across the stacked sets whenever the center cooperates.

The base game runs on Mystery Stacked Reels. Every reel carries stacked mystery positions, and at spin start each reel's stack resolves to the same single symbol drawn from a pool of 2 or 3 candidates. The Red Flame Wild only enters the base game this way - it never appears on the strips naturally - so every base-game wild line comes from a mystery stack landing on the wild symbol. The Bonus scatter is excluded from the mystery pool. Four dragon medallions in red, blue, purple and green sit as carved jade-and-gold portraits above stylised gem-cut card values, and all four dragons pay identically at 5, 20 and 50x line for 3, 4 and 5 of a kind. This was the 2016 release that opened the Dragon Spin series, eventually extending into the Crosslink follow-up.
