What Electric Man Actually Is
It is a browser-based puzzle game that has been around since the mid-2000s. You wire up circuits, route power, solve logic problems using AND gates, OR gates, NOT gates, and basic electronic components. Nothing fancy. It runs directly in the browser, no install needed, and the entire source code is available if you want to dig into how the circuit evaluator works. The game gives you a grid. You place components, connect wires, and try to get power from a source to a target. Each level adds complexity. Early levels are trivial. By the time you hit the logic gate sections, you need to actually think about boolean algebra rather than just guessing connections. I spent about three weeks playing through all levels on and off, and the difficulty curve is fair until the later puzzles where timing and multiple power sources overlap. The core mechanic is that the circuit solver checks for valid paths from positive to negative terminals and evaluates logic states at each tick. Wires have propagation delay. This matters because a common mistake beginners make is placing a NOT gate on a signal that is toggling too fast, which causes flickering states in the simulation. The fix is usually just adding a buffer or a D flip-flop to stabilize the signal before it reaches the gate.
How to play through the harder levels
I will say upfront that the game has no built-in hint system. You are on your own. My approach was always to sketch the circuit on paper first. Once I had the logic mapped out, I placed components on the grid rather than placing randomly and hoping for the best. This cut my solving time significantly, especially for levels with multiple outputs. One problem I ran into repeatedly was level layouts where the wire length mattered. The puzzle validator counts total wire usage, and exceeding the budget marks the level as failed even if the circuit works logically. I eventually figured out that rerouting through empty adjacent cells rather than diagonal shortcuts saved enough wire to pass. Not obvious at all without testing it yourself. For the XOR gate sections, the standard trick is building it from AND, OR, and NOT gates rather than trying to use some hidden component. The game does not provide an XOR gate primitive. I wasted about two hours on one level before realizing this. Once I constructed the proper expression, it took three minutes to wire up.
Where to find it
Electric Man is available as an open source project on GitHub. The original browser version is hosted there, and the latest release includes the full puzzle set plus a level editor so you can build and share your own circuits. No download required for the web version. If you want the offline desktop build, the repository has compiled versions for Windows and macOS. I have been using the GitHub page for several years and it still works without issues. The game is technically very small. There is no save system. Each session is one sitting. If you close the tab you lose your progress. I lost about six hours of work once because I assumed there was auto-save. There is not. There is also no multiplayer or competitive mode. Some people treat it as a casual pastime and stop after the first twenty levels. The deeper puzzle content only opens up after you complete the main campaign, and honestly the later levels can feel repetitive because the component palette does not expand much beyond the logic gate section. Also worth noting: the circuit simulator runs synchronously, which means very large or complex circuits can lag in older browsers. I experienced noticeable slowdown on a midrange laptop running Chrome when a level required managing more than forty components at once. Switching to Firefox resolved the performance issue entirely. If you run into this, try a different browser before assuming the game is broken.
Get the Full Details
Overall the game is decent for learning basic logic circuit design. It is not a replacement for any real electronics software like LTspice or Falstad, but for understanding how gates combine and how to think about power routing in a constrained grid, it does its job adequately. Nothing more, nothing less.
