Professional Safecracker

Players have to open a locked drawer and there is a combination safe lock they have to turn to right positions. The problem is, the hint with the combination shows only the first number, the rest is unreadable. Players have to listen for distinct sounds as they turn the lock and find two remaining positions. When they do that, the drawer opens. Electronics needed: 🕵️‍♂️ Safecracker sensor, 🧩 Universal puzzle controller, 🎁 Drawer output set
