A GREAT ESL REVISION GAME

I and my students really like this game. 
Try it out, I'm sure it will be fun!!!

RULES OF THE GAME:

Before class prepare a key of what weapons will go in each grid space.
Divide the class into teams, each person has 3 lives. 
Draw a 10x10 grid on the board. 
Ask students the revision questions, whoever gets the question right can choose a square. Tell the student what the square contains.
Gun= take one life point away.
Two guns = Take two life points from the same person or one each of 2 people.
Bomb= The answer-er loses one life point.
Fire= The whole team loses one life point.
Heart= Add one life point.
The team that still has people alive in the end wins.
Change the names of the values if you wish.
