@dailyideasguy: 🕵️♂️ This Norwegian cold-case game is going viral. Here’s how it works: You get mailed real evidence: police reports, surveillance photos, newspaper clippings, and 5 sealed clue envelopes. No app. No timer. Just you, your friends, and a murder to solve. It’s called Detective for a Day by @detective_for_a_day — a low-tech, high-engagement business idea turning living rooms into crime scenes. Would you try solving a murder from home?
