Saturday's Scoop6 win and bonus fund will likely be more than GB£ 2.5 million after it went without a winner last weekend.
The game has enjoyed a surge in popularity in 2014 after a number of particularly large rollover jackpots. Now Betfred's Tote wants to capitalise on this by making changes to the way the pools are generated.
A new starting fund pool will be created to ensure there is a "rollover" prize to play for each week, regardless of whether or not the win fund is claimed.
Totepool MD Phil Siers explained: "The addition of a starting fund will mean there will always be a rollover for customers to aim at, regardless of whether the win fund is won the week before. We think this addition will prove popular with players as they will be able to look forward to big-money rollovers every Saturday."
The cost of playing will remain at GB£ 2 but the way that money is split will change:
35% to the win fund
17.5% to the place fund
12.5% to the bonus fund
5% to the new starting fund
30% in deductions to the operator
The Tote will begin the starting fund with GB£ 250,000 of its own.
