On the left you can see some categories - for example DOGS. But what kind of dogs? When you click START, you will see fifteen cards. When you turn over three cards in one category, click on the category (in white on the left). Keep going until you have used all the cards. Watch the clock on the right. When all the bars have gone, you have to start again.
Games 2, 3 and 4 are the same, but at more advanced levels.
