Virtual Circuit Board

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 come 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.
