The variable reel sizes create a dynamic probability space. With an average of ~4.5 symbols per reel, the typical spin offers around 8,300 ways. The avalanche multiplier ladder is the key mechanic: in Free Falls, the non-resetting 3x-15x multiplier means that long avalanche chains can produce enormous payouts. The 8% Earthquake chance further boosts win potential by expanding the grid mid-spin.
Engine Mechanics: Megaways engine generates 2-7 symbols per reel (up to 117,649 ways). Avalanche wins cascade with increasing multipliers (1x→2x→3x→5x base, 3x→6x→9x→15x free fall). Uncharted free fall triggered by 3+ scatters.
RTP Control: Target RTP is configurable via Dashboard → Game Control tab. The engine uses dynamic payout adjustment: rtpFactor = targetRTP / currentRTP clamped to [0.1, 2.5]. Over ~500 rounds, actual RTP converges to target ±1%.
House Edge: 4.0% at default. Revenue per 1,000 rounds at €1 avg bet: ~€40.
Variance Profile: High variance - base game provides steady small wins, free fall multiplier chain creates highest exposure. Max win: 21,000x bet.
