Web Game

Hi, sorry. We have been so busy...
We have uploaded our first web version of the game. You need Firefox and Geogebra, and one spanish dictionary.
It isn´t working correctly but we´d like to share with you. We will try to translate it and after this we´ll ask your pupils for some help.
Look at the image. Does it remain you one of the puzzles?

Inside a hermetically sealed room there is a light bulb, and outside the room there are three switches. Only one of the three lights the bulb. While the door is closed, you can press the switches as often as you want. But when you open the door, you have to say which of the 3 switches lights the bulb.


This is not Fermat´s room but it may be a nice training for the weekend:
Click on the red square and move it with the mouse. When it touches the black border or a blue rectangle, you are dead.
18 seconds alive is a really good mark... for your mouse
