At certain times, Colossus will make you an offer to buy a ticket that is still eligible to win a jackpot or consolation prize. These offers are typically made between the end of one leg in a pool and the start of the next leg. In some instances, Cash Out offers are also made at half-times or breaks in play.
Colossus allows players to accept Cash Out offers fully or in 10% increments of their ticket, enabling you to lock in a payout for part of your ticket, while retaining a chance to win part of the jackpot or consolation prize you were originally playing for.
