Design a DIY escape room in my home

Help me design an escape room game in my home. Players: [NUMBER and ages] Space: [e.g. "living room and hallway", "one bedroom"] Theme: [e.g. "pirate treasure", "secret lab", "birthday surprise", "surprise me"] Time limit: [e.g. 45 minutes] Materials I have or can buy cheaply: [e.g. padlocks, envelopes, a flashlight, books, a jigsaw] Difficulty: [first-timers / experienced puzzlers] Design: 1. A short story intro I can read aloud, with a clear goal. 2. 6-8 puzzles that chain together: each solution unlocks the next clue. Use a mix of types (search, code or cipher, logic, pattern, physical) so different players get to shine. 3. A flow chart of the puzzle order, including which can be solved at the same time so a group doesn't stand around. 4. For each puzzle: setup, what players find, the solution, and two hints of increasing help. 5. A hint system and how I time it (e.g. a free hint every 10 minutes). 6. A setup checklist and a reset checklist. 7. A finale and a quick debrief. Safety rules: never actually lock anyone in a room or block an exit; keep "locks" on boxes, drawers, or envelopes; no climbing, no hiding clues near hot or electrical items, and keep small parts away from young children.
