Great condition.
Used wall mounted ring puzzle. Players find these  6 small and large rings in the game room. Great for a collection item. Once assembled they need to be clued to put the letters in specific order. Can be done by using any of the 6 letters; across, up, down, etc
Once aligned in correct order then it will trigger any 12V device.
This is made with hall sensors and magnets and a relay board 12V.
The rings have felt on the back so they move smoothly.
Worked for 5 yrs in escape room.
