Cascading Wins and Lit Reels Progression
Every winning combination triggers a cascade — symbols vanish, new ones drop in. Each consecutive cascade lights another reel from left to right, accompanied by a distinctive ding sound. Six lit reels in a row unlock the Reel King Feature with miniature slot machines that spin for guaranteed payouts.
The horizontal reel above positions 2-6 adds an extra layer of complexity. Jester Hat Wilds appear exclusively here, substituting all symbols and often completing chains that wouldn’t connect otherwise.
🎯 Expert Tip: Chase cascades aggressively in base game. Six consecutive tumbles trigger the feature, and each cascade moves you one step closer regardless of win size.
Reel King Bonus Feature
Three tiers exist:
Reel King (6 cascades) — spawns 1-2 mini slots
Super King (7 cascades) — spawns 2-3 mini slots
Mega King (8+ cascades) — spawns 3-6 mini slots
Each mini slot plays independently on a 3-reel, single-payline format. Land three matching 7s for instant payouts: Mixed 7s pay 1x, Blue 7s 2x, Yellow 7s 5x, Red 7s 10x. Three lit reels advance you one position on the Free Spins Trail. A losing spin removes that Reel King from play.
Reach the trail’s end to trigger Free Spins — anywhere from 8 to 25 spins depending on which King tier you activated. During free spins, cascades build an unlimited multiplier that never resets. Light all six reels red during the bonus, and additional Reel Kings appear with extra spins and multiplier boosts.
