Shortest Circuit

Route the current. Light every bulb. Find the shortest path.

Shortest Circuit is a brain-bending puzzle game set on a glowing circuit board. A power source sends an electrical pulse toward a receiver — but bulbs scattered across the grid need power too. Your job: redirect the current so it reaches every lightbulb on its way home.

The twist? The engine finds every shortest path simultaneously. Block one route and the current splits, branches, and flows through all equally-short alternatives at once. Mastering that split is the key to solving the trickiest boards.

HOW TO PLAY
• Tap a diode arrow to rotate it — steering current in a new direction
• Drag moveable blocks to open or seal off paths
• Route the current through every lightbulb to complete the level
• Fewer moves earns a higher score — perfectionists welcome

FEATURES
• Handcrafted campaign levels with increasing complexity
• Community-made levels from players around the world
• Built-in level editor — design and share your own puzzles
• Global leaderboards to chase personal bests
• Some levels include a limited battery: every move counts
• Clean dark theme with a satisfying PCB visual style

THE CATCH
Ground faults are instant game over. One-way diodes force your hand. Blocks that can only move once lock in place forever. Every decision matters — and there's always one more level to try.
