Is there a required age to enter and play the games?

Strictly 21+.

Yes, it is treated like a bar. All patrons must be 21 or older, with an ID check at the door.

Logan Arcade is still primarily a bar, so as law permits, patrons are limited to a minimum age of 21, with proof of ID.

It's 21+ exclusively. They're very strict about checking IDs

When I went they had someone checking IDs at the door. Not sure if they throw Xs on hands if you are under 21. I'd imagine it's 18+ atleast
