Tap two nodes to draw a wire. Light up every bulb to win!
🔋 What makes a bulb light up?
A bulb glows only when electricity can flow in a complete loop: from the battery's + side, through wires, through the bulb, and back to the battery's − side.

Break the loop anywhere — bulb goes dark. That's why your light switch works: it just breaks the circuit.
📐 Two ways to connect bulbsSeries: bulbs share one wire path. Remove one → all go dark. Parallel: each bulb has its own wire path. Remove one → others stay lit. Most house wiring is parallel.

📘 Electricity Lesson
⚡ Closed circuit rule
Electric current flows ONLY in a closed loop. Battery + → wire → bulb → wire → battery −. Break the loop anywhere, no current.
complete loop = bulb lights
🔢 Series vs ParallelSeries: all parts in ONE loop. Same current, voltage adds up across each bulb. If one bulb breaks, ALL go off. V = V₁ + V₂ + V₃
Parallel: each bulb has its OWN branch. Same voltage across each, current adds up. One bulb out, others stay lit. I = I₁ + I₂ + I₃
💡 Play tip
Connect every node so current can flow from + to −. Use the fewest wires possible for bonus coins!
