Microgaming’s four-tiered Mega progressive slots is standing at an all-time high, £8.2m for UK players or €8.2m for those playing in Europe.
The Mega progressive is used on games such as Mega Moolah, Mega Moolah Summertime and The Dark Knight.
John Quinn, head of casino at Microgaming, said: “We’ve watched the progressive ticker grow considerably over the last few months and anticipation is building as to when it’s going to be triggered.
“When hit, it is going to be a life-changing amount for one very lucky player and, as always, they will take home the win in one lump sum. We don’t believe in annuities!”
