Megaways Slots Explained: The Mechanic Behind Millions
Megaways is a patented slot mechanic developed by Big Time Gaming (BTG) that revolutionized how slot machines pay. Instead of fixed symbols per reel, each spin randomly assigns a different number of symbols to each reel — and the number of ways to win changes every single spin.
How Megaways Works
In a standard 6-reel Megaways game, each reel can display 2–7 symbols per spin. The total number of ways to win equals the product of symbols showing on each reel. When all 6 reels show 7 symbols: 7×7×7×7×7×7 = 117,649 ways to win. This number changes every spin, creating constant visual excitement.
Cascade (Avalanche) Feature
All Megaways slots use cascading reels: winning symbols explode and new ones fall down to replace them, giving multiple wins from a single spin. Each cascade typically increases a multiplier (1×, 2×, 3×... unlimited) — the biggest wins come from long cascade chains during free spins.
Free Spins in Megaways
Most Megaways games include a free spins round with an increasing multiplier that starts at 1× and grows with each cascade. This creates the potential for huge payouts when a long cascade chain meets a high multiplier. Buy Feature allows purchasing free spins directly (typically 40–100× your bet).
