Geoff and Paul discuss the long-running agile training exercise “The Ball Point Game,” often used in in-person Certified ScrumMaster courses to teach iterative improvement, inspect-and-adapt, and self-organisation. They explain the setup (typically 10–12 people and many tennis-ball-sized balls) and core rules: each ball must touch everyone, have airtime between people, not be passed to a closest neighbour, return to the starter, and dropped/removed balls incur a penalty while the team self-scores. The game is played over eight timed iterations with planning, running, scoring, and re-estimating, and teams usually improve after a chaotic first round. They highlight learning outcomes around experimentation, the dangers of targets and competition, facilitation/Scrum Master questioning, lean waste and flow, leadership dynamics, and contrasts with waterfall-style planning, and they plan to share a PDF of rules and invite listeners to submit scores or videos.
