1. Before the writing phase begins, the judge can initiate a secret rule. The judge may write along with any exercise, as usual, and may collect on an Acrobal bet if they do so.
2. At any point at within the first five minutes of a round, any player can add a secret rule to
Acrobal, Wabish, Lipogram exercises. They play their secret rule by revealing it. Doing so causes the other players to adjust their writing to fit the new rule.
A secret tile can be played revealed; words
of this letter can be included in the current exercise, or the letter can be used to replace a letter already part of the constraint.
