In “The game” after “the Dealer may start a Game between any two Players” add “(these players are known as the games Participants)”

Add a new subrule to “The Game” called “Wagers”

Each Player has a non-negative integer amount of Contanti, which by default is ₤1000.

If they are not a participant of a given game, and the game is not closed, then, as an atomic action, a player may make a Wager on the game by first spending X Contanti, where X is at least 10, and then making a comment on the post for that game which follows the format “WAGER: [name] X [codeword]” where [name] is the name of one of the two participants in the game, and [codeword] is an English word which has not be used for a wager on the same game. The Wager is then considered to be Open.

If a Wager is Open, and one of the Participants takes a turn in game which the Wager was made in, the Wager ceases to be Open and the Player who made the wager gains X Contanti.

If a Wager is Open, any other Player who is not a Participant in the game which the Wager was made in (or the Player who made the Wager) may, as an atomic action, spend X Contanti and make a comment on the same post saying “ACCEPT: [codeword]” where [codeword] is the English word used in the Open Wager they are accepting. The Wager then ceases to be open, and instead becomes Pending.

When a game ends, for every pending Wager on that game, if the participant whom the Wager named earned a Peg from the game, the player who made the wager gains 2*X Contanti (where X is the integer value associated with the given Wager). If the participant whom the Wager did not name earned a Peg from the game, the player who accepted the wager gains 2*X Contanti
