About this app

Copperworks turns a circuit board into a puzzle playground. Kids wire batteries, LEDs, bulbs, buzzers and motors, and every puzzle runs on real electronics math, so what works in the game works on a real workbench too.

LEARN BY BUILDING
• Close the loop, mind the polarity and route around mounting holes
• Pick the right resistor so an LED doesn't pop, using Ohm's law
• Build series and parallel circuits and see the difference in brightness
• Spot and fix short circuits
• Make AND and OR logic gates from switches, the same idea inside every computer chip
• Design circuit boards with jumpers that hop over other traces, just like vias on a real PCB
• Measure volts and milliamps with a built-in multimeter

1000 LEVELS IN THREE TRACKS
Basics (500 levels), Sensors & Dials (250) and Transistors (250). Each track starts with step-by-step lessons, then gets harder level by level. Every level is checked to make sure it can be solved.

BLANK BOARDS: BUILD IT FROM SCRATCH
More and more levels start with an empty board. Kids place the battery, LEDs, resistors and every bit of copper themselves. Any board can also be rebuilt from scratch with one tap.

THE JOB BOARD
Clients send real circuit problems, like "my model train headlight needs between 15 and 20 mA". Kids design the whole circuit to solve each one, and the jobs never run out.

CHAPTER BOSSES, TROPHIES AND GADGET CARDS
Every chapter ends with a boss build. Finishing a chapter wins a collectible gadget card with a real-world electronics fact, and 27 trophies reward milestones.

HEARTS
A heart breaks when a circuit breaks: a popped LED or a short circuit, just like on a real workbench. Hearts refill on their own over time.

DAILY CHALLENGE
A new puzzle every day, free for everyone. Keep your daily streak going!

EARN RANKS AND BOARD COLORS
Stars unlock new ranks, from Spark Starter to Legendary Inventor, and new circuit-board colors: Ocean Blue, Racing Red, Stealth Black and more. Real boards come in all these colors too.

INVENT IN THE FREE LAB
Every part, unlimited. Build anything and watch it work.

HELP WHEN STUCK
Volt, the friendly lightning bolt, coaches every step. "Show me" hints light up the next part to place, with 3 free hints every day.

MADE FOR FAMILIES
• No ads, ever
• No accounts, no chat, no tracking, no data collected
• Works fully offline
• Every purchase sits behind a grown-ups-only question
• Real-world safety tips: small batteries only, never wall power

FREE TO PLAY
250 levels are free: the first 100 Basics levels, 75 Sensors & Dials levels and 75 Transistors levels, plus the Daily Challenge and the Free Lab. One purchase unlocks the full game: all 1000 levels, the Job Board and double hearts, forever.
