The Peephole is one of the green puzzle challenges for Sigils of Elohim. There's 2 Moving Mines and 2 Jammers.
How To Solve[]
Move the first Jammer to open the door that's already open. Grab the Jammer from the door that you just opened, and take that out, go back to the peephole and jam the closest mine. Take the second jammer and jam the second mine and pick up your prize.
