Begin with clear consent, access preference forms, and a safety briefing. Offer transportation details, restroom locations, and quiet waiting spaces. Use observation checklists focused on interaction clarity, not player performance. Debrief with open questions, then compensate promptly. Summaries should translate feedback into specific fixes, owners, and deadlines to ensure accountability.
Build tiered hints that escalate from gentle nudges to explicit steps, available by tactile cards, QR audio, or facilitator readouts. Timebox offers to avoid overhelping. Track which hints are used to tune difficulty. Preserve puzzles where discovery remains joyful even when assistance becomes necessary under time limits.
