Can Cylon players use secret codes, touch or gestures, or talk away from the table to coordinate?

Question

Accepted Answer

No. The rulebook does not name codes outright, but repliers agree that secret signals and off-table talk conflict with its secrecy rules, because communication must stay open to everyone at the table. One reply says a group may still settle it with its own house rule.
