How to play

At the top you see the target angle, for example 135°.
Tap the circle or drag the pointer until the sector matches your estimate. 0° is at the top, angles are measured clockwise.
Press “Check” to see the real angle, your deviation in degrees and your points.
After three angles you get your total score and personal best.

Train your eye for angles

Angle Guesser is a visual estimation game for anyone who wants to judge angles without a protractor. Instead of a finished angle you only get a number of degrees – and you set the angle yourself. Round values like 90° or 180° are quick, odd angles like 37° or 251° are where it gets tricky.

Every degree off costs points: an exact hit earns 100 points, 5° off still gives about 70, and 10° off roughly half. With a little practice you build a reliable feel for angles – useful for drawing, crafts, maths or parking.
