Game Mechanics
The Megaways engine delivers between 324 and 117,649 ways each spin. Six vertical reels shift between 2-7 symbols, while a horizontal reel above positions 2-5 adds four extra symbols. Wins form left to right with at least three matching symbols on adjacent reels — except diamonds, which pay from just two.
Cascades trigger after every win. Successful symbols explode, new ones drop in, and the cycle continues until no fresh combinations appear. During base game these cascades simply extend your spin. In free spins though, each cascade increments an unlimited win multiplier that never resets between spins.
Mystery TNT barrels land anywhere and all reveal the same random symbol simultaneously. Wilds appear only on the horizontal reel, substituting everything except scatters. The dynamite bundle slides left across that top row, occasionally creating those perfect substitution moments.
Bonus Features
Four scatter symbols award 12 free spins. Each additional scatter adds five more, maxing at 22 spins for six scatters. The real excitement lives in the multiplier system — starts at 1x, increases by 1x per cascade, and crucially carries forward through all remaining spins.
Retriggers happen only via the horizontal reel during the feature. Three scatters add five spins, four scatters grant ten. Combined with a climbing multiplier that might already sit at 15x or 20x, retriggers can push sessions into serious territory.
Before free spins begin, you can gamble on a pie wheel. Win and your spins increase toward the 30 maximum. Lose and they vanish entirely. The segments reflect true odds — no hidden traps, just pure risk assessment.
🎯 Expert Tip: The multiplier never resets between free spins, so even modest cascade chains build serious momentum. A 6x multiplier on spin one becomes 12x after two more cascades, dramatically shifting the math on every subsequent win.

Diamonds break the standard pattern: 2x for two symbols, 5x for three, 10x for four, 25x for five, 50x for six. With 117,649 ways active and a climbing multiplier, even medium symbols generate respectable returns during extended cascade sequences.
