Place chips on a 6×6 board and build circuits that generate energy. Completed circuits stay on the board, generate energy every turn, and can be reused in the next circuit. Connect circuits within a limited number of turns and reach the target score.

Connected circuits generate energy every turn
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 generate energy every turn. Chips used in one circuit can also be used in the next. Reach the target score before the stage runs out of turns.
Three kinds of circuits
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.
