Millionaire Rush Megaclusters

How wins are formed

As a cluster-pay title, wins land whenever at least five matching symbols sit adjacent to one another, either vertically or horizontally, rather than along fixed paylines. Standard gem-style token symbols pay out 0.5x to 1x the stake for a minimum five-of-a-kind cluster, scaling up to 30x-50x the stake for larger clusters of 25 or more matching symbols, giving the game a genuinely wide payout spread depending on how big a cluster manages to form.

RTP and what it means for you

Millionaire Rush Megaclusters carries an RTP of 96.44%, a strong figure that sits comfortably above the market average and reflects well on Big Time Gaming's typically reliable stat disclosures.

Volatility explained

This is a high-volatility slot, powered by the combination of an expanding cluster grid and the additional Megatrail system layered on top. Wins can be sparse between bigger hits, but the payout scaling on larger clusters gives the volatility real teeth when it pays off.

Max win and betting range

The maximum win reaches an impressive 55,060x the stake, driven by the combined potential of Megaclusters and Megatrail working together. Stakes run from 0.20 up to 20 per spin, a workable range for both cautious and high-stake players chasing the bigger multiples.

Verdict

Millionaire Rush Megaclusters brings Big Time Gaming's trademark mechanical complexity to a lively quiz-show-inspired package, and the combination of an expanding grid with the Megatrail system gives it a genuinely distinct feel compared with standard cluster slots. It's a strong option for players who enjoy intricate, high-ceiling mechanics over simple payline structures, and the wide gap between the minimum five-symbol cluster payout and the maximum 25-plus cluster payout keeps every winning spin feeling meaningfully different.
