How to play
The goal
A boulder with a value on it, like 4.7 kΩ or 0.002 A, rolls toward your cannon. Pick the answer that means the same amount (for example 4,700 Ω or 2 mA) to blast it before it reaches you.
Controls
- Click or tap one of the four answers, or press 1–4.
- The speaker button in the top corner turns sound on or off.
Lives, levels and the boss
You have 3 lives. A wrong answer or a boulder that reaches the cannon costs one. The game starts with kilo (k) and milli (m); mega (M) and micro (µ) unlock as you go. There are 10 levels, each ending in a boss.
Quick reference
- M mega = ×1,000,000
- k kilo = ×1,000
- m milli = ÷1,000 (0.001)
- µ micro = ÷1,000,000 (0.000001)
Tip: moving one prefix step (k → base → m) moves the decimal point three places.
