If you have 3 separate bets, rolling the winnings over into the next bet if you win, then they are just that: 3 SEPARATE bets. You have the choice to stop at any time and collect your winnings. Turnover (and profit on turnover) is calculated on each separate bet.

An Allup bet is ONE bet and if that initial bet is $10 then turnover is $10. In the above example you are not risking $210 because you are still mid bet. There is no option to collect mid bet.

If the first bet loses then you lose $10. (LOT 100%). If the first bet wins and the second bet loses, you still lose $10 because there was never any way of collecting after the first bet won.
