LogicForge

Logic circuits from two gates

LogicForge is a PC logic-building game where you create circuits from NOT and AND gates, then use them to build a computer. There are no ready-made building blocks: you make OR, XOR, multiplexers, adders, registers, an ALU and, eventually, an 8-bit CPU with an assembler.

A solved circuit can be saved as a component in your library and reused inside other circuits, with as many layers of nesting as you need. The live view lets you open any instance and inspect its inner circuit and real values. Story mode has 102 chapters across fifteen acts and three worlds: circuits, assembly and Python. Each world has a character who grows as you progress. Chapters set a goal, but leave the solution to you; stars reward correctness and economy.
