I learned about this fantastic game accidentally while visiting the teflgeek's blog. Great blog with a lot of useful ideas!
I immediately saw how I could use it with my students for revising certain grammar or vocabulary items.
I made a grid of 30 squares with numbers for the questions and some additional "home" and "centre" squares. I prepared a list of questions 1-30 which had to be answered by looking for answers in the course book.
The teams picked a colour and took turns in choosing a square and providing the correct answer. If the answer was right, the square took the team's colour. If the answer was wrong, the team lost the move and the square remained blank.
To make the game a little more challenging, the teams could get an additional point if they won 3 squares in a row (see squares 2, 11 and base) or 3 squares touching with their sides in a different configuration. They could also win one of the central squares if they surrounded it "by their colour" (see squares 9, 3, 15 + the central square). They could also surround the opponent's square on 3 sides and then the square was won over and changed its colour.
The original game was slightly different but I easily adapted it to the level of my 14 year old students.
To tell the truth, counting the points for me was the trickiest part as I was sitting at the computer and using Paint to change the colour of the squares right away plus checking if the answers given by the students were correct. In the end students helped me to count the points and made sure I did not overlook anything.
This is how the grid looked at the end of the game.
My biggest thanks to David Petrie whose idea I took, adapted and used very successfully. My students loved the game and, as usual in such cases, asked for more. I am thinking about it.
Just one question to @teflgeek. Why "domination"?
