How Megaways Works
The BTG engine explained — from random reel modifiers to unlimited multipliers
Random Reel Modifier
On every spin the BTG engine independently randomises the number of symbols shown on each reel — anywhere from 2 to 7 per reel. This happens before any win calculation, so the grid is never the same twice.
Up to 117,649 Ways
With six reels each showing up to 7 symbols, the maximum ways to win is 7⁶ = 117,649. On a spin where every reel shows 2 symbols, only 64 ways exist. The average sits much lower than the headline figure — expect typical spins to land in the 1,000–50,000 range.
Cascade (Tumble) Mechanic
Winning symbols explode off the reels and new ones fall in from above. If the replacement symbols form another win, the process repeats — a single spin can produce a chain of cascades, each counted as its own win.
Free Spins & Multipliers
The free spins round is where variance peaks. Most Megaways games carry an unlimited progressive multiplier: the multiplier starts at ×1 and increases by 1 with every cascade. A 15-cascade chain means the 15th win is paid at ×15 — and it keeps climbing for the entire free spins round.
Feature Drop (Demo Only in UK)
Many Megaways games include a Feature Drop (bonus buy) that lets players pay a set stake multiple — typically 50–100× — to enter free spins directly. This feature is available in demo mode but is banned for real-money play under UKGC rules.
Licensed Engine
BTG licences the Megaways mechanic to other studios. Blueprint, Barcrest, Red Tiger, and Pragmatic all build their own Megaways titles on the same core engine — which is why Fishin' Frenzy Megaways and Bonanza play so similarly despite coming from different developers.

What Are Megaways Slots?
Megaways is a patented slot mechanic developed by Big Time Gaming (BTG) and launched in 2016 with Dragon Born. The engine works by randomising the number of symbols displayed on each reel on every spin — instead of a fixed 3×5 grid, a Megaways game might show 2 symbols on one reel and 7 on another.
On a 6-reel game with up to 7 symbols per reel, the maths gives you 7×7×7×7×7×7 = 117,649 possible ways to win. Combined with cascading reels (winning symbols disappear and new ones fall in), free spin multipliers, and the Feature Drop (instant bonus buy), Megaways slots became the most-played category in UK online casinos.
BTG licences the Megaways engine to other developers — that's why you'll find Megaways versions of classics like Fishin' Frenzy (Blueprint) and Rainbow Riches (Barcrest). Each uses the same engine but wraps it in a different theme and bonus structure.
Most Megaways slots are high volatility by design. The base game pays infrequently — the real action is concentrated in the free spins round, where cascading wins combined with an unlimited progressive multiplier can produce 1,000× or more from a single bonus. That extreme variance is exactly why demo play is strongly recommended before staking real money: the gaps between significant wins can be long, and understanding the game's rhythm first prevents surprises.
One important UK-specific note: the Buy Feature (also called Feature Drop) — which lets players pay a fixed multiple of their stake to enter the free spins directly — is prohibited for real-money play in the UK under current UKGC regulations. In demo mode, however, you can use it freely to experience the free spins round at will. Outside the UK, Feature Drop is available at qualifying licensed casinos where local regulations permit it.
The Megaways licence has expanded widely since BTG's first release. Today you can find Megaways versions of established UK favourites from Blueprint Gaming, Pragmatic Play, NetEnt, Red Tiger, and Relax Gaming — each bringing their own bonus structure and theme while sharing the same dynamic reel engine. Blueprint's titles tend to feature the popular British pub-machine personality with well-known characters; Pragmatic Play's Megaways games are built for maximum multiplier potential; NetEnt's Twin Spin Megaways grafts the Twin Reels sync mechanic onto the BTG grid; Red Tiger's Gonzo's Quest Megaways adds stone-carved cascading reels to the original Gonzo theme. The shared engine means the core variance profile is recognisable across all of them — the individuality lives in the free spins mechanics and bonus structures.
Managing your bankroll on Megaways slots deserves particular attention because the variance is genuinely high. In the base game, it is entirely normal to spin 50–100 times without a notable win — Megaways games are calibrated to pack the bulk of their RTP into the free spins round. The practical implication: play with a session bankroll of at least 100× your stake and set a maximum loss before you begin. Demo mode exists for this exact purpose — spending time in a Megaways demo before playing for real money gives you a realistic feel for dry-spell frequency, how often the free spins trigger naturally, and what the bonus round is actually capable of delivering.

Megaways Slots — FAQ
What are Megaways slots?
Megaways is a game engine by Big Time Gaming (BTG) that randomises the number of symbols on each reel each spin — up to 117,649 ways to win on a standard 6-reel setup. It's licensed to many other providers, so you'll find Megaways versions of many classic slots.
Which Megaways slot has the best RTP?
White Rabbit Megaways tops the list at 97.7% RTP. Rainbow Riches Megaways and Fishin' Frenzy Megaways both sit around 95%. Higher RTP = better long-run theoretical return.
Are Megaways slots high volatility?
Most Megaways slots are high volatility — meaning wins are less frequent but potentially larger. This makes them exciting for bonus hunters but requires a patient bankroll. Free demo mode is the best way to experience this without risk.
What is the difference between Megaways and regular slots?
Regular slots have a fixed number of paylines or ways to win. Megaways slots have a variable grid — each spin can show different symbol counts per reel, creating a fresh win structure on every spin.
Can I trigger free spins on Megaways demos?
Yes — all demo features work exactly like the real-money version. You can trigger free spin rounds, unlimited multipliers, and bonus features without depositing anything.
What is the difference between Cascades and Megaways?
Cascades and Megaways are separate mechanics that often appear together but are not the same thing. Cascades describe what happens after a win — winning symbols are removed and new ones fall in from above, potentially creating chain wins from a single spin. Megaways describes the variable grid — how many symbols are displayed per reel changes each spin, altering the total ways to win. A slot can have Megaways without Cascades (though most combine both), and many non-Megaways slots use Cascades.
Which providers make Megaways slots?
BTG created the Megaways mechanic and licences it to other studios. Key licensees include Blueprint Gaming (Fishin' Frenzy Megaways, Genie Jackpots Megaways), Pragmatic Play (The Dog House Megaways, Buffalo King Megaways), NetEnt (Twin Spin Megaways), Red Tiger (Gonzo's Quest Megaways), and Relax Gaming (Templar Tumble Megaways). Each provider builds their own bonus structure on top of the shared core engine.
How should I manage my bankroll on Megaways slots?
Budget for variance. High-volatility Megaways slots can produce 50–100 non-winning spins in the base game before a significant payout — this is by design. A practical rule: bring at least 100× your stake as a session bankroll and set a loss limit before you start. Never increase your bet after a losing run in an attempt to recover — each spin is independent. Free demos are the best way to feel a game's dry-spell duration before risking real money.
