Who Wants To Be A Millionaire Megapays Slot Review — Big Time Gaming
Who Wants To Be A Millionaire Megapays is a Megaways slot built by Big Time Gaming, the studio that created the Megaways engine and released this title on 23 August 2021. The game runs on 6 reels with up to 117,649 ways to win per spin, carries a 96.38% RTP and a high volatility profile, and its ceiling sits at 72,310 times the stake. Big Time Gaming, founded in 2011 in Australia, licenses its Megaways mechanic to other studios, but this particular title is one of its own releases.
Core Gameplay Experience
Each spin on Who Wants To Be A Millionaire Megapays draws from a 6-reel Megaways grid, meaning the number of active ways changes from spin to spin and can reach 117,649 at the widest configuration. That variability is what drives the pace of the game: some spins offer only a fraction of the maximum ways, others open the board up fully, and the visible symbol count shifts constantly rather than staying fixed the way it does on a classic fixed-payline slot.
The visual theme leans on diamonds, gemstones and a blue-and-black colour palette, a design language shared with other Money and Luxury-themed slots in Big Time Gaming’s catalogue, which readers can browse under the Money & Luxury theme. It keeps the screen dark and the symbols bright, which suits a game built around cascading wins rather than a busy narrative backdrop.
Features and Mechanics
The core loop combines Multiway (+1024) mechanics with an avalanche cascade: winning symbols clear and new ones drop in, and each cascade can trigger further wins from the same spin without a fresh bet. The Megaways system layers on top of that, resetting the reel heights and the number of ways after every cascade. Wild symbols and scatters support the base game, while a jackpot feature and a free spins round with multipliers give the higher-value outcomes their reach — the multipliers stack across free spins rather than resetting, which is where the 72,310x ceiling becomes reachable. A risky, or gamble, double-or-nothing option is also available for players who want to push a smaller win further at the cost of losing it outright.
RTP, Volatility and Payout Model
Who Wants To Be A Millionaire Megapays pays back 96.38% of wagered stakes over the long run and is classed as high volatility, meaning wins are less frequent but can be considerably larger when the cascades and free spins line up. A 96.38% RTP sits in the 76th percentile of the 4,462 slots with a published RTP in our catalog, against a catalog median of 96%, so this title returns slightly more than the typical slot on paper over a long enough sample. The 72,310x max win is higher than 96% of the 3,455 slots with a published max win in our catalog, where the usual ceiling sits around 2,500x — a figure that reflects the top of the free spins multiplier chain, not a realistic single-session expectation. In practice, the high volatility label means a session’s outcome depends heavily on whether the free spins round and its multipliers trigger; base-game spins alone rarely move the balance much.
Long series of spins without a meaningful win are a realistic outcome at this volatility level, since most of the payout weight sits in the free spins multipliers rather than the base game. Sizing bets to the bankroll and setting a loss limit before playing matters more here than on lower-volatility titles, and the demo mode is a way to see the cascade and free spins rhythm before wagering anything.

Who Wants To Be A Millionaire Megapays ranks 41st of 53 high-volatility, 50-or-more-payline titles ordered by RTP, placing it below White Rabbit and StarQuest but ahead of Dragon Born within that comparable group. The table shows RTP clustering tightly between 95% and roughly 97.7% across these Big Time Gaming Megaways titles, so the practical choice between them comes down more to paylines and theme than to a meaningful RTP gap.
Similar Megaways Slots from Other Studios
| Game | Studio | RTP | Volatility | Max win |
|---|---|---|---|---|
| Golden Treasures | Atomic Slot Lab | 95.52% | Medium | |
| Grand Royale | AGS | 95.95% | High | x10,000 |
| Flashback Heroes | Arcadem | 95% | High | |
| Riches of the Nile | AGS | 94.12% | High | x1,050 |
Against shared-mechanic titles from other studios, Who Wants To Be A Millionaire Megapays’ 72,310x ceiling dwarfs the x10,000 and x1,050 caps published for Grand Royale and Riches of the Nile, at the cost of the same high-volatility trade-off those two carry. Players who want a gentler ride can look at Golden Treasures, the only medium-volatility title of this group.
This slot fits players who accept high volatility and want free spins multipliers to do most of the payout work, with a bankroll sized for extended dry stretches between hits. It is not a good match for players who want frequent small wins or who plan to spend limited session time chasing the top-end multiplier, since that ceiling depends on stacking multipliers across triggered free spins rather than base-game play.
