Counters over the line equate to how much money is in the player’s individual prize pot and the contestant with the least amount in each round is eliminated.
Each normal counter is worth £50 but there are also a number of special counters in the machine which can win even better prizes.
One such counter is the x2 counter, which means if pushed over the line, doubles the contestant’s winnings on the same drop.
This means in theory, contestants could end up doubling their winnings to £20,000 in the slim chance the jackpot double counter fell at the same time.
