What Are Megaways Slots?
Megaways is a slot mechanic invented by Big Time Gaming (BTG) in 2015 with Dragon Born. The reels can show between 2 and 7 symbols on each spin, randomly. The total number of ways to win is calculated by multiplying the symbol counts across reels:
Ways to win = Reel 1 symbols × Reel 2 symbols × ... × Reel 6 symbols Min: 2 × 2 × 2 × 2 × 2 × 2 = 64 ways Max: 7 × 7 × 7 × 7 × 7 × 7 = 117,649 ways
Some Megaways slots (like Buffalo King and White Rabbit) increase the max by adding a 7th reel or expanding bonus rounds, pushing the max past 200,000 ways.
Key Megaways Features
- Variable reels — symbol counts change every spin, so no two spins are identical
- Cascading wins — winning symbols are removed and replaced (called “Reactions” or “Tumbling”), enabling multiple wins per spin
- Unlimited multiplier in free spins — most Megaways slots have a multiplier that increases with each cascade in the bonus round, with no upper cap
- High volatility — most Megaways slots are high or very-high volatility, so bonus features can pay massive amounts but the base game pays rarely
- Bonus buy — many Megaways slots let you skip directly to the free spin round for 50-100x your stake (banned in some jurisdictions including the UK)
Megaways Providers
Big Time Gaming invented the mechanic and licenses it to other providers. Major Megaways licensees:
- Big Time Gaming (BTG) — the original. Best titles: Bonanza, White Rabbit, Extra Chilli, Lil Devil
- Pragmatic Play — strong catalogue under licence. Best titles: Buffalo King, Power of Thor, Wild Wild Riches
- Red Tiger / NetEnt — Gonzo’s Quest Megaways (the original Gonzo’s Quest converted), Dragon’s Fire
- Blueprint Gaming — strong catalogue including the Genie Jackpots and Vikings franchises
- iSoftBet — Twin Spin Megaways and other branded Megaways slots
- Reel Play — sub-brand of BTG with their own Megaways portfolio
Strategy: How to Play Megaways
Bankroll
Megaways slots are high-volatility. Plan for losing streaks of 100-200 spins between wins. Standard recommendation: bankroll of at least 100× your bet level. If you want to bet €1 per spin, have €100 ready. For a €5 spin, have €500.
Bet Sizing
Megaways slots are extremely punishing for over-betting. The math is built around scattered low-value spins with rare massive payouts. Bet too high and a single dry session can deplete your bankroll. Bet conservatively — under 1% of bankroll per spin is typical advice.
Free Spins Round
The free spins / bonus round is where Megaways slots pay big. The multiplier increases with each cascade — and there’s typically no upper cap. A long chain of cascades can produce 1,000x+ wins. Look for slots where the multiplier persists between spins (not resetting each spin).
Bonus Buy
Many Megaways slots let you skip to the bonus round by paying 50-100× your stake. This is banned in the UK and at some Tier-1 licensed casinos. It changes the mathematics in unpredictable ways and is generally NOT recommended for most players — the bonus round still has the slot’s overall RTP, you just pay a premium for guaranteed access.
