If the line you drew is within the outline’s range, the game shows you the full image. This can be a cat, a mouse, or any cute image designed in the game. You’ll pass the level. But if your line is too long or too short, you lose, but you can try again. The game might seem easy, but is actually quite difficult if you’re not used to estimating line length. The game is a good exercise for figures and even patience to get things right. It’s especially enjoyable for children learning about different objects and animals.

Deceptive simplicity rears its head in this game. It is difficult to estimate the appropriate length of the line segment you need. Complex figures may have longer or shorter outlines than their size suggests. You shouldn’t be surprised if it takes you several attempts to get past some of the harder figures. Extra difficult figures have very small thresholds.

The game is a simple exercise in temperance. You learn not to overdo or underdo each line with every picture. To master this game, have a little patience and take note of your previous attempts and learn from them.
