Indie developer HS Games has released Eternal Circuit Board, a puzzle game for Steam on Windows, on November 3. The game is priced at $4.99, with a 15% launch discount available for the first 7 days. A free demo is also available for players to try out. The game involves placing colored chips on a 6×6 board to complete circuits and generate energy. Completed circuits stay on the board, and Triangle circuits generate energy every turn. The game also features three kinds of circuits, including Triangle, Sustain, and Line circuits, each with its own unique properties. The demo includes 10 stages, including the tutorial, and allows players to carry over their progress to the full game. HS Games, a team of two, created the game for players to enjoy and encourages feedback on their Discord or X channels.
