TeraWatt

Build complete circuits. Outsmart every board.

Rotate wires, junctions, and components to connect power to ground. Every puzzle is procedurally generated — no two boards play the same.

Start simple, then master real circuit mechanics:

Diodes enforce one-way current flow
Short circuits punish bad paths with an instant board reset
Color LEDs mix additively — blend red, green, and blue to hit target colors at the ground terminal
7 difficulty tiers from 4x4 Beginner boards to 8x8 Grandmaster grids, each introducing new mechanics as you progress. Unlock tiers by earning score, then climb the Grandmaster ranking system with 10 milestone titles up to Ohm Supreme.

Take on specialist challenges:

Wire Maze — navigate a massive 10x10 grid
Minefield — solve around 7 short circuits
Spectrum — mix 5+ color LEDs with decoy colors trying to corrupt your signal
Compete in the Daily Challenge — a shared Grandmaster puzzle with the same seed for every player, every day. Build your streak.

Earn energy from every solve and spend it on 29 unlockable cosmetics — animated wire themes, board frames with unique corner art, dynamic backgrounds like Starfield and Deep Space, and 7 victory effects from Fireworks to Black Hole.

Share any puzzle with a compact 8-character code. Load codes from friends to race the same board.

No ads. No paywalls. No timers. Just puzzles.
