In our class, we always play a game called hand tennis. The point is to the get from the bottom left block to the upper left block, during the process you need to try and eliminate your opponents by either hitting the ball high or low so that they can't volley back.
The blocks are called baby, jack, queen and King. The point is to reach King and stay there as long as possible.
If the King says "lightening" and the Queen gets eliminated they go straight out.
We play it at break when we are not playing Pokemon or having races.
