Preparation
Choose Letter in the generator to create a file for that paper. Downloadable samples are A4: when trying them on Letter, fit to the printable area rather than printing at actual size and clipping the edges.
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.
