Add the following sub rule to “The Gamblers” called “The Back Room”

Props are publicly tracked and consist of the following information

* The name of the Punter offering the Prop (the Offer)
* Optionally, the name of the Punter accepting the Prop (The Accept). A Prop without an Accept is considered to be Empty
* The Buy In, which must be a positive integer number of Readies
* The Reward, which must be a positive integer number of Readies which is greater than the Buy In
* The Event, A single, specific Sporting Event (identified by the Sport and the date on which it will occur) in which the Prop was created before the Sporting Event had occurred
* The Outcome, An outcome (from the Potential Outcomes for the Sport of that Sporting Event)

A Punter may at any time Offer a Prop by reducing their Readies selecting the Buy In, Reward, Event, and Outcome and then Reducing their Readies by the Reward—A Punter may perform this action if it would cause their Readies minus the Stakes of any open Bets that Punter to be less than zero.

If the sporting event for an Empty Prop has not yet occurred, A Punter who is not the Offer for that Prop may Accept the Prop, marking themselves as the Accept by transferring the Buy In in Readies from themselves to the Offer for that Buy In - A Punter may perform this action if it would cause their Readies minus the Stakes of any open Bets that Punter to be less than zero.

When making or accepting a Prop, the Punter doing so should privately message the Bookie so that the Bookie may better track that Punters Readies.

After a Sporting Event has occurred, then the Bookie should process each Prop for that sporting event as follows:

- If the Prop has an Accept, and the Outcome of the Sporting Event matches the Outcome of the Prop, then the Accept gets the reward for the Prop in Readies.
- Otherwise the Offer gets the reward for the Prop in Readies.
