The Beast

You have to roll a six to enter your body into play
No other number will do

But if you cannot get it done
Your turn then simply passes on
To the one next in line

After three sixes in a row
You can't go on like this anymore
Four of the same passes on the turn

When you come to a plain square
And someone is already there
You may have to take his place

Sometimes, though you thought it through
There is just no way to move
