The win is the 25th since the prize went live in 2014, and is above the €3,816,752 average paid out every 9 weeks on average. The game is a sequel to the popular Mega Fortune slot, which brought record-breaking progressive jackpots to punters around the world. Dreams is very similar to the original, with the only real difference being different color schemes and symbols, but the slot otherwise plays identical.
The game's jackpot grows with every spin of the reels and pays out when punters enter the jackpot bonus round, where they then need to proceed to the innermost jackpot wheel.

Commenting on the win NetEnt's Henrik Fagerlund said, "We are thrilled to announce the latest jumbo jackpot winner on Mega Fortune Dreams. Players know that the game is proven to pay out the biggest prizes - just as this €4.3 million windfall shows - and we are delighted for the latest recipient of a life-changing sum."
