There’s more than likely a large junk of you out there that have played Jenga with a blindfold. Undoubtedly, there’s even a larger chunk that have played without it. Either way, this would make for a great upfront volunteer game.
I would play this game with large block Jenga. To play recruit a handful of kids to come upfront. Give them a good look at the Jenga stack and then place a blindfold on them. Make sure they know how to play. Add music to confuse and a turn time limit to speed it along.
Here are online instructions to make large blocks from Home Depot.
