Everything you need to know about playing and winning.
Guess the Angle is an educational geometry game where you have three attempts to guess the correct measurement of various angles. It teaches angle measurement through interactive visual challenges.
You win by guessing the angle within 5 degrees of the correct measurement. The game provides visual feedback and teaches you about different angle types like acute, obtuse, and right angles.
The difficulty varies by angle type. Some angles like 90° and 45° are easy to identify, while complex angles in irregular shapes can be challenging. You can enable 'Protractor Master Mode' for advanced geometry challenges.
The daily challenge features one new angle puzzle each day. However, there are practice modes and training grounds where you can play unlimited challenges to improve your geometry skills.
If you fail to guess the angle within 5 degrees after 3 tries, the game ends and the correct measurement is revealed along with geometry tips. Don't worry! A new challenge is available the next day to try again.
