About This Demo

The demo includes 10 stages, including the tutorial. Your demo progress carries over the first time you launch the full game on the same PC.

Circuits that keep on working

A puzzle game where you place colored chips one at a time on a 6×6 board. Arrange chips in the right shape to complete a circuit and generate energy. Completed circuits stay on the board and keep working every turn. Reach the target score before the stage runs out of turns.

Three kinds of circuits

  • Triangle circuits — Place 3 Energy chips in a right angle to generate energy every turn.
  • Sustain circuits — Tiles between two Protect chips are shielded from blockades.
  • Line circuits — Line up 4 Draw chips to gain Wild chips that can stand in for any chip.
A single chip can complete several circuits at once.

Encroaching blockades

Blockade warnings appear on the board, and tiles left unprotected become unusable. Extend your circuits or shore up your defenses — every placement shapes the board.

Features

  • A tutorial and 60 stages
  • A preview that shows which circuits a placement completes and how much energy it earns, before you commit
  • Stage-specific twists such as bonus colors and challenges
  • Play with mouse or gamepad
