Before the jackpot-linked Megapays version arrived, Big Time Gaming's first pass at the famous quiz show licence came in the form of Who Wants to Be a Millionaire Megaways — notably the studio's first fully branded release, built around its trademark high-volatility Megaways engine rather than a progressive jackpot network.
The format translates the show faithfully: a single contestant faces a run of multiple-choice questions, collecting a growing cash prize with every correct answer while climbing a prize ladder toward increasingly difficult questions and bigger rewards. A set of lifelines helps the contestant along the way, and safety-net values mean a wrong answer doesn't always wipe out the accumulated prize once a "locked" milestone has been passed. That entire structure has been reworked into the slot's free spins feature, complete with the option to walk away with winnings rather than risk falling further down the ladder.
The base game runs across 6 reels using BTG's standard Megaways structure, generating up to 117,649 ways to win as the symbol count shifts on every spin. It's the free spins round where the branding really comes alive, translating the show's rising-stakes prize ladder into an escalating in-game multiplier structure that can build toward some genuinely enormous outcomes.
The RTP sits at 96.27%, a solid and competitive figure that lands comfortably above the industry midpoint, giving players a fair long-run baseline before the free spins feature adds its own layer of value.
Volatility is rated medium, a touch gentler than some of Big Time Gaming's more extreme releases, though the free spins prize-ladder mechanic still carries serious upside. The max win reaches 70,000x the stake overall, with up to 20,000x achievable in the base game alone before the free spins round is even triggered. Stakes range from 20p/c up to £/€50 per spin.
Who Wants to Be a Millionaire Megaways stands apart from its later Megapays sibling by keeping the prize ladder and multiplier build entirely within the game itself rather than tying it to an external jackpot network. The 96.27% RTP, medium volatility, and towering 70,000x ceiling make for a well-rounded, faithfully branded package.
