🎯 What is Angle?

Angle is the daily angle-estimation game from angle.wtf. Each day the puzzle drops a real photo with two lines drawn on it and asks you to guess the angle between them. Your guess is scored by absolute distance from the true answer — within 1 degree is a perfect score, within 5 degrees is excellent, and within 15 degrees is still a comfortable win.

The pool spans everyday scenes — buildings, shadows, faces, objects — and the lines are drawn at natural angles (roof slopes, shadow edges, the corner of a book). It's a small but surprisingly tricky format that rewards visual intuition.

💡 How to Play Angle

Open angle.wtf to see today's photograph with two colored lines drawn on it and the prompt to enter the angle between them.
Estimate the angle visually. Look for known reference points — a right angle is 90°, a flat line is 0° or 180°, an equilateral triangle's apex is 60°.
Type your guess into the input. The site accepts any whole number from 1 to 180.
Submit your guess. Angle reveals the true angle and your error margin — within 1° is a perfect score, within 5° is excellent, and the further off you are the worse you score.
Use the visual cues. Shadows, building edges, and the geometry of objects in the frame are usually close enough to known angles to estimate.
Solve within the attempt limit (usually two guesses) and a shareable score card appears. Streaks save to your browser.
