Preparation
Count players rather than everyone attending. Prepare a distinct board per player; Table of 12 contains 12 boards. If fewer guests play, set the remaining boards aside without duplicating those in use.
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.
