A short round can be a complete evening
Choose a game people can enter quickly, pair players when useful and agree on the ending. If adapting rules, explain the changes before play. Avoid stretching the session until everyone is tired or one person gets a desired result.
Before starting, check the materials and adult-help notes in the guide. Begin with a small version and keep a familiar alternative available. If the idea does not fit the day, simplify the task or choose a different pace; a longer list is not always the answer.
