Ones and Zeroes

There are some BUGs need to be fix. You can only load 4 Customization Circuits and the customization Circuits will not shows up unless you restart the game. And also you cannot delete half of the circuits. Once you delete, every joint will disappeare. You cannot customize your circuits route as well which make your page look massy. DFF don't have a reset button and ~Q output. However it is a very good game for DSP simulation. It will be great if the author improve this game a little more.

This is a sandbox, not a game. Unless I am blind and missed it, there are no levels/challenges apart from being asked to replicate a simple truth table between inputs and outputs. And instead of letting you build the more advanced components (multiplexers, flip-flops, registers, adders, counters, maybe even a full CPU) yourself, it just shows you everything built already in the tutorials. The dev says he is doing a huge overhaul currently. Maybe that includes actual levels. Until then, only buy this, if you are interested in a sandbox. If you like games like MHRD, TIS or Shenzhen IO, you probably won't be happy with this.

The Dwarf Fortress of circuit simulators, i.e. the world is your sandbox

Buggy: With the endless mode you have a truth table that covers the inputs (not the bug but bad for people getting into it), the truth table itself duplicates if you press "try this solution" and it's not connected to the output. The same happens when you press "Generate truth table". I wont recommend this until (and if) the bugs get patched, but I'll say it's a good simulator for circuits. I wont recommend buying this at full price if you're planning to buy it, rather wait until it's on special (During Christmas or another holiday). Graphics: Generic Circuit Board GUI Sound: None Gameplay: Challenges, which have the bugs listed. Scrollable: CircuitBoard? No. EDIT: Yes. With arrow keys. Space For Creation Of Circuits: Small-Medium. Save Location Adjustable? No You'll probably end up creating parts, to deal with the small size of the board itself. I tried to like it, but due to the lack of space, the bugs, the lack of save location change, the smallness of the board. It would get frustrating fast. I'll give it a 5/10, the proper simulation of hardware being the ONLY redeeming quality. I'll change my review to positive if the bugs get fixed and if they board becomes scrollable.

A fairly simple circuit simulator with some decent tutorials and the ability to make one's own custom components. Has a simple set of I/O challenges and a friendly developer who maintains good communications with the users when suggestions or bugs are found.

I should preface this review by stating that I have no logic gate experience beyond simply being able to walk myself through the reasoning behind all the AND, OR, XOR, etc very slowly. The tutorial is not the prettiest thing, and you have to hunt for it through the menu's rather than it being rather obvious from the start. I have been able to learn the basics such that I am able to solve the occasional beginner's Challenge. I haven't tried intermediate yet, as I'm still learning to identify solutions rather than helplessly try all the gates until I start to get progress (Yeah, I know, "git gud"). Overall, I find this a very fun game with a large chunk of educational potential. However, what I do feel is that there is a disconnect between the tutorial/challenges "type" of gameplay and the "construct your own projects!" opportunities. I think this could be a bit more directed to help simpletons like myself try to figure out WHAT to make and how to go about doing it. I do think that there is attempts at this due to the thorough tutorial, but I think a bit more hand-holding would increase the likelihood that I would play this game again and REALLY dig into the creative aspects of this.
