For Place pools, we always display the full headline prize instead of the fractional prize (proportionate to the stake per line you have selected, as is the norm with all other Colossus pools). This is because it is possible for Place tickets to have multiple winning lines and potentially exceed the stated "playing for" prize.
For example, in a Place pool with a prize of £10,000, a 12-line ticket with a 10p stake per line would be playing with 0.1 units per line for £1,000. However, the maximum prize for which the ticket is eligible depends on the number of winning lines that the ticket contains.
The simplest solution therefore in Place pools is to display the static total pool prize regardless of the stake per line for which a ticket is playing.
