You can improve your observation skills in different ways, but gaming is the most enjoyable and accessible. The Cars Find the Differences game challenges you to find the differences between pictures of different cars. You must find seven differences in just one minute. If you don't have enough time, you can add it by watching a short advertisement. But if you are focused and extremely attentive, even one minute will be enough for you to complete the task. Three wrong clicks will use up the error limit and the game will end. Cars Find the Differences has twenty levels and if you haven't completed the previous one, the next one won't open.
