Circuit Stack is a fast-paced puzzle game about building unstable power networks under pressure.

Drop modular cable pieces onto the board and create a grind. Then connect batteries and trigger massive overload chains before the board fills up. Every connection matters. Every misplaced piece can block your setup or even your board.

-----------------

How to play: 
Your objective is simple: Build. Connect. Overload.

Controls, move pieces:

• Arrow left/right → Move
• Up Arrow → Rotate
• Down Arrow → Soft Drop
• Space → Hard Drop

The grid starts filling. Pieces piling up. Keeping the system under control becomes the real challenge. Short-circuit the grid, to keep the field clean. 

Pieces:

There are two piece types: cables and batteries.
All pieces have connectors.

When a battery connects to a cable network, the entire connected network lights up.

Battery types:

• Small battery: 1 block, 1 connector
• Large battery: 2x2 blocks, 2 connectors

If a second battery connects to the same powered network, it short-circuits and the entire connected network explodes.

-----------------

The core gameplay blends classic falling-block strategy with chain reactions, routing logic and risk management. Batteries act as volatile power sources: connect them correctly and energy surges through your circuit. Build larger networks, create combo overloads, and survive increasingly chaotic waves of components.

Features:

• Real-time falling-block gameplay
• Electricity-based connection mechanics
• Chain reactions and overload combos
• Dynamic difficulty scaling
• Sci-fi industrial aesthetic
• Satisfying explosions, sparks, and power effects
• Multiple piece types and routing strategies
• Highscore-focused arcade gameplay
