This idea is cool, and comes as a suggestion from our very own Ce'Nedra!
Today we have a Paper "Laser" Maze which you can set up at home. Seems like the hallway is the optimal in-home location for this one. You can make it as easy or as challenging as you wish.
I would suggests setting a course for the others in your bubble to challenge them. Then each take turns at building the maze, and challenging the others.

You will see the instructions say use crepe paper or streamers, I think to make it a little more "lockdown" themed, you could use a toilet paper, break into that panic buying stash of paper and have some fun!
