If any Colossus pool is not won or is won by less than a unit, the proportion of stakes bet into the pool that is not won will be allocated to a subsequent pool of the same type. We refer to this amount as a “rollover”.
If there is any rollover amount in a pool, you can see this by clicking on “More info” in the pool header.
For example, if £10,000 of net stakes* are bet into a Correct Score Pick 4 and 0.5 units win the pool, £5,000 will be given as a winning payout to the 0.5 units and the remaining £5,000 will be allocated into a subsequent Correct Score Pick 4 pool.
If the net stakes and rollover amount combined exceed the guarantee, then the prize available on the pool will increase above the guarantee and subsequently grow as each bet is placed. That’s when you see the “Rollover” icon next to the pool name on the pools list and in the pool header!
* Net stakes are player stakes after Colossus’ standard 30% deduction (unless otherwise stated in our Terms of play).
