Johari Four-Square

Let's play a game of four-square. I've got a ball...here, see?

It's a rubber band ball. Took forever to make. Very colorful.

I'll start as king, in the King's square: "Open".

Do we have three other people?

Good. 

I bounce the ball in front of me, to the square labeled "Hidden."

Now that's silly, where'd the player go?

Re-do. 

I bounce the ball to the corner, in the square labeled "Unknown."

Where did the ball go?

Start over.

I bounce the ball to my left, to the square labeled "Blind".

The game continues, but the ball never returns to my square.
