Partial Cash Out lets you collect some of your winnings, while leaving a bit of your stake on - so you can lock-in a profit, whatever the outcome.
It's worth noting that cashouts can also yield several cash prizes. A punter can request a partial withdrawal during a match, while as a result, their bet on the event's outcome may also be profitable. In this case, the user will have the opportunity to withdraw the remaining prize after the game.
