Retrieve the Locks is a Arduino-powered project that at it’s core is a puzzle game. It works similarly to how “Operation” functions, whereas the main goal is to complete a task without touching two components together. In this case, it’s trying to avoid touching the handles to the long metal wire that runs above the board, but its also the only way to get the keys over to the locks.
The barriers add a cooperative element to the task, as either switch actually raises the barrier on the opposite side – forcing you to work with your partner to win. Above the middle locks, is your “lives” counter. Each time you accidentally touch the handles to the wire, you lose one life, and if you lose all three before getting all the locks unlocked? You lose!
