Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Early Access allows me to better understand how players interact with the game by learning what they create, how they use the available tool set, what they might need to improve their workflow when creating circuits, and so on. This community feedback allows me to fine-tune the game features to match the ideal sandbox experience for designing, programming, decorating, and simulating logic circuits.”

Approximately how long will this game be in Early Access?

“It is difficult to give an estimate time frame since the community feedback will guide the development, but since most of the core features are already in place I estimate it should take no longer than a year, although this estimate might change as I learn more and better understand how players experience the game.”

How is the full version planned to differ from the Early Access version?

“Upon reaching full release Virtual Circuit Board will have its drawing tools along with its other features fine-tuned to give the best circuit design and simulation experience.”

What is the current state of the Early Access version?

“The game is fully playable and it is possible to create and simulate complex circuits, although overall stability is expected to improve during Early Access.”

Will the game be priced differently during and after Early Access?

“The price might increase depending on how much new content is added to the game.”

How are you planning on involving the Community in your development process?

“I will constantly gather feedback and interact with the community to fine-tune Virtual Circuit Board to the players' needs.”

About This Game



Virtual Circuit Board, or VCB, is a sandbox-only drawing-based logic simulator featuring an assembler and a powerful simulation engine. All of it designed to give you the freedom to build and experiment with logic circuits to your heart’s content.

Set your own goals

In VCB you will set your own goals of what and how you want to build, it does not comes with tutorials, levels, or challenges, and it will not teach you digital logic or assembly. VCB's development philosophy is aimed toward delivering a fresh sandbox experience for players who already have some basic knowledge about logic gates and circuits.

Powerful Simulation

High-performant deterministic simulation with adjustable speed and the ability to pause and advance by steps. Simulate with a frequency of up to millions of updates per second.

Assembly

Assembly editor where you can define your own instructions to create a program that will be assembled to a Virtual Memory that can be accessed by your circuits.

Editing and Simulating

Working in VCB is separated in two modes, while editing you can use the drawing tools to modify your circuit and the assembly editor to write programs, and during simulation you can see your circuit running, interact with it, and watch the assembly instructions being executed.

Drawing-based Interface

Build circuits by drawing color-coded entities like logic gates and traces, and use the specialized tools such as the Array to optimize your workflow by drawing multiple traces simultaneously. Both the electronic components and the traces support multiple input and output connections.

Decoration

Customize the appearance of circuits by drawing in the decoration layers that override the component's default colors. This allows you to create things such as buttons and labels that change appearance depending on the component's state.
