Preparation
For a full-board round, every square must be marked. Announce this pattern before handing out boards so nobody stops after a row. Keep caller tiles visible and check all squares when confirming the result.
Check the sample
Download the two free boards and caller tiles. Check edges, readability and that each player has markers before printing for the whole group. The two-board sample is separate from a pack of 12 or 30 distinct boards.
During the gathering
Agree on the pattern before starting and reveal one caller tile at a time. Keep used tiles visible to check the result. Guests may pass on conversation prompts. No alcohol or betting is needed.
