Five box requires a row of five decent boxes and two players, one at each end.
For your first turn you have to throw the ball into the box closest to your
opponent (your fifth box, his first), without him catching it on the fly. In
other words, the ball has to take a bounce (and only one bounce) before he
catches it or it leaves his box. If he catches it on a fly, or if you missed
the box, it's the opponent's turn; if he didn't catch it, you throw again.
This time you throw it to your fourth box (his second), where it had to bounce
once (and only once), then bounce once or more times in the fifth box before
he catches it. If he catches it before it bounces in the last box, then you
don't advance but continue trying for those two bounces. If you get it, your
next attempt is to get one bounce in the third, fourth, and fifth boxes.
Ultimately, you get it to a point where you've made the ball bounce once in
all five boxes. At this point you reverse, trying for four bounces in four
boxes, then three bounces in three then two and finally just throwing it into
his closest box on a bounce before he catches it.
