      How to Play — Sine Launcher

      🎯 Objective

      Defend 150 dancing bunnies by using trigonometry to shoot down spaceships carrying Bad words before they reach the ground!

      📐 Setup Phase

      You'll be shown a triangle with vertices A, B, and C. Study it carefully during the 10-minute calculation period (you can end early). Use the calculator to compute angles and distances you'll need for shooting.

      🎮 Game Phase (20 Rounds)

      1. Answer a question: Math questions based on triangles and trigonometry. Get it right to wear a protective helmet!
      2. Spaceship drops: A spaceship with a Bad word and a number drops from C toward B.
      3. Shooting duel: The spaceship shoots at you (50% hit chance, 2 damage without helmet, 1 with helmet). You shoot a Good word sign from your launcher at A.
      4. Aiming: Enter angle and distance to hit the spaceship's center (within 1 meter). If you hit it, the ship flies away and your score increases. If you miss, it crashes and kills that many bunnies.
      5. Game over: When health reaches 0, you can't fire anymore. After 20 rounds, your final score is recorded!

      📊 Levels

      • Level 1: Right triangle (a=30, b=40, c=50). Questions on SOHCAHTOA, Pythagorean Theorem.
      • Level 2: Isosceles triangle (a=60, b=50, c=50). Includes isosceles triangle properties.
      • Level 3: Scalene triangle (a=60, b=81-99, c=180-b). Includes Law of Sines and Cosines.

      💡 Tips

      • C is always directly above B; use this to set up your coordinate system!
      • The spaceship shoots first at a random time. Stay ready!
      • Both projectiles move at 20× the spaceship's falling speed.
      • Angles must differ by at least 1° between shots.

      Game Flow

      1. Study Phase (up to 10 minutes): Examine the triangle, use the calculator to compute critical angles and distances.

      2. Combat Phase (20 rounds): Answer question → Shoot spaceship → Next round

      Shooting Mechanics

      Your launcher is positioned at vertex A. Set the angle and distance to hit the spaceship's center as it falls from C toward B.

      Hit within 1 meter: spaceship flies away, you gain points. Miss: spaceship crashes, bunnies die.

      Health System

      Start with 10 health. Spaceship has 50% chance to hit you. Without helmet: −2 HP. With helmet: −1 HP. At 0 HP, you can't fire anymore.

      Scoring

      Each spaceship carries a random number (20 numbers sum to 150). Hitting it adds that number to your score.
