It will take a few moments for the pictures to download; when the timer
appears in the button below the squares, you can begin playing. If the timer
doesn't appear after one minute, click the button. To reset the game, click the timer button. If you have a slow internet connection,
your first game may be slow due to all the pictures that need to be downloaded.
If you've never played Concentration, here's how. Each
of the squares above hides one of 18 different images. Click on any two squares to expose the hidden images. If they
match exactly, they will stay
exposed. If they don't, they will both hide again and you can click two more
images. The goal is to remember where the images are so that you can expose all
18 pairs. The timer is just there to help you keep track of your progress as you
get better at playing and finish more quickly.
