WHY THE GAME WORKS
Turn Unit Circle Recall Into a Game
If 30° takes one second but 240° takes eight, both are correct but only one is automatic. The game makes that difference visible and gives you a reason to play one more round.

How to Play the Unit Circle Game
Use the timer to measure retrieval, not guessing. Accuracy comes first; speed matters after the values are stable.
Pick your level
Level 1 builds degrees and radians. Level 2 focuses on coordinates. Level 3 drills sine, cosine, and tangent. Level 4 mixes everything for a full unit circle game.
How scoring works
Every correct answer is worth 100 points. Each additional answer in a row adds 50 more. In timed modes, every second you have left adds 10. Your best score stays on your device.
How streaks work
Correct answers build your current streak and your best streak. A wrong answer resets the current streak, so accuracy matters as much as speed when you are chasing a higher score.
SCORE HIGHER
How to Score Higher in the Unit Circle Game
Fast recall grows from a small set of dependable patterns rather than memorizing dozens of unrelated facts.
Start with the first-quadrant special angles 30°, 45°, and 60°. Know their radian forms and exact coordinate pairs. Then use reference angles to move those same magnitudes into Quadrants II, III, and IV, changing only the signs. When coordinates are automatic, remember that cosine is the x-coordinate and sine is the y-coordinate; tangent is y divided by x. A useful speed run should expose which connection still requires extra steps. If accuracy falls, learn the unit circle pattern, use fill-in unit circle practice to rebuild it from memory, or check the unit circle cheat sheet before returning to the timer.
