The core objective is to defend a planet or spaceship from approaching asteroids. To "blast" an asteroid, you must correctly answer the math problem displayed on it. Operation Modes

  • Concept: converting kilometers to meters, use scientific notation for huge or tiny numbers.
  • Short story: “Tiny Rock, Big Number” — an asteroid 0.0003 km across? What is that in meters and millimeters?
  • Practice: convert 0.0003 km, 14,500 m, 3.2×10^5 m to consistent units.
  • Challenge: estimate how many coffee beans fit across an asteroid 1 km wide (assume bean ≈ 1 cm).

But then the asteroid fought back.

Difficulty Scaling: V3 features a more intelligent "Level Up" mechanic. The game monitors your speed and adjusts the velocity of the asteroids to keep you challenged but not overwhelmed.
