Mathematical quiz game
Find π
See the point. Read the angle. Find the radians.
A fast unit-circle quiz where a point appears at an angle that is a multiple of 30° or 45°. Convert the angle to radians, choose the correct π-based answer, and keep the streak alive.

Interface concept — not an interactive demo
Game loop
Trigonometry under time pressure
The previous Android release used a simple loop: identify the angle represented by a point on the unit circle, convert degrees to radians, and select the correct answer. A correct answer increases the score; a mistake resets progress.
The visual direction from the Figma design turns that exercise into a compact arcade-style quiz: graph paper, a unit circle, digital score displays, a countdown timer, and large answer buttons.
Previous Android release
Small rules. Huge question space.
Question angles are based on familiar unit-circle increments.
The historical Google Play description stated more than 300,000 question and answer combinations.
Answer quickly before the round timer runs out.
Build a streak and try to beat your previous score.
Design language
Chalkboard math meets arcade UI
Menu direction from Figma: green classroom board, hand-drawn equations, bold π mark, and tactile utility buttons.
Game direction from Figma: graph-paper background, charcoal panels, neon-green timer/score, and orange feedback accents.
