Who Wants to Be a Millionaire Megaways (Big Time Gaming) RTP review: 96.24%
Hot Seat: gambling your free spins like prize money
The bonus is a direct lift from the TV format it licenses, and it's the best reason this game exists. Trigger the feature and you enter the Hot Seat: a money-ladder gamble where you can risk your awarded free-spins count for progressively larger amounts, climbing tier by tier exactly as a contestant would — complete with safety-net levels and lifeline-style assists the paytable documents. Cash out early with a modest award, or gamble to the top rungs for a spin count that turns the subsequent round into a marathon. It is the same psychological trap as the show, monetised: every player believes they'd stop at the right rung. Once the spins begin, BTG's standard bonus engine takes over — an unlimited win multiplier that grows with each cascading reaction and never resets for the duration.
A Bonanza descendant in a suit
Mechanically this 2018 release is close kin to Bonanza: six reels, up to 117,649 Megaways, avalanche-style cascades clearing winners for new symbols. It was BTG's first licensed-brand slot, and the branding budget shows in the production. The maths sit a notch below the original — 96.24% fixed versus Bonanza's 96.00%... in the game's favour, actually: 96.24% is the better figure, though volatility here is rated a harsher 5/5 ("Very High") against Bonanza's 4. The certified cap is also nearly double at 50,000x. In effect: same engine, slightly better price, meaningfully rougher distribution — the Hot Seat gamble alone widens outcomes considerably.
Points of order before you sit down
- The ladder is optional. You can take the initial spin award and decline the Hot Seat entirely — know the rungs before deciding.
- Multiplier compounds without limit. As across BTG's cascade games, bonus length is worth more than bonus frequency.
- Max-win figures vary by source. 50,000x is certified; treat larger circulating numbers as theory.
- Stake range 0.2–20, and no bonus-buy exists in any market.

Our verdict on Who Wants to Be a Millionaire Megaways
Skip if: you'd take the spins and run every time; without the gamble this is a rougher Bonanza in different clothes
Millionaire Megaways succeeds where most branded slots fail: the licence adds a mechanic, not just a logo. The Hot Seat gamble converts the bonus trigger into the game's most consequential moment, and the fixed 96.24% build with a 50,000x certified ceiling prices the experience fairly for its class. Its weakness is inherited — a base game that exists to be endured — and its Very High variance rating means the ladder's temptation lands on already-streaky foundations. Decide your cash-out rung before the bonus ever triggers, hold to it, and the game becomes what the show always pretended to be: a test of discipline dressed as a quiz.
