Rename the rule Savings to Wagers. Change its text to read as follows:

Each Wordsmith has a publicly tracked number of Coins, defaulting to 0.

Each Wordsmith has a Wager, privately tracked by the Puzzler, which can be either a number between 0 to 5 inclusive or a null value, and which defaults to a null value.

If a Wordsmith has not posted a Backronym since the most recent Acrogenerate, as a Virtual Action they may set their Wager to a valid value.

In the rule Scoring, change the following two bullet points:

Subtract the Savings of the author of that Backronym from that author’s Points, to a minimum of 0 Points, then set that author’s Savings to 0.
Take the difference of that author’s Points before the previous step and after the previous step and add that difference to that author’s Coins.

to read:

If the author of the Backronym’s Wager has the exact same value as the Points they gained from that Backronym then they also gain Coins equal to the same amount. Otherwise they lose one Coin, to a minimum of zero coins.
