About This Game

Simple in concept, but very challenging and rewarding, Circuits is a musical puzzle game that requires careful listening to complete each level.

The goal of Circuits

piece together the different parts of a song. Sounds easy, but maybe not.

As we love music, we wanted to make a game that gives the player an insight into how music is created and makes listening the core part of the experience. Packed with beautifullly designed minimal graphics, to not disturb the focus of the game, and right now 25 different songs for the player to reconstruct.

So if you like music, you will like Circuits .


  • Engaging gameplay that gives an insight into music creation for players
  • A soundtrack mix of electronic ambient,dubstep, and epic orchestra composed by David García ( Deadlight, Rime...)
  • Beautiful minimal design
  • And a Turbo.

Playing Circuits is like trying to transpose a song someone else wrote, while having an overly vague and harsh on looker constantly jump in to tell you you're doing something wrong. It's a dull lesson in tedious frustration, constantly imposing illogical and repetitive mechanics on the player while providing no incentive or reward for figuring them out. The ideas behind Circuits sound intriguing on paper, but the foundation developer Digital Tentacle has laid them out is simply not there.

Circuits is a game about building music, or that's what it's supposed to be. In reality it's the act of memorizing a sequence of sounds, and then placing audio samples in the correct order until you've recreated the track exactly. This is expanded upon by new mechanics such as repeating samples and loops, but they are never used in a way that actually expands the gameplay into something more compelling, instead only making tracks more confusing and difficult to put together.

This is the fault of both the opaque design at the core of Circuits, and the fact that the tracks you are creating are often made up of far more sounds and layers than you actually place on your board. This makes deciphering what sample is meant to go where incredibly challenging in a way that feels poorly thought out and rarely allows you to readily hear the mistakes you make, as everything is buried under so many other sounds to begin with. It also flies in the face of the very premise of the game that you are building these tracks yourself, as so much of them are completely separate from the gameplay and simply added onto the samples you placed. Finally the soundtrack is enormously disappointing for a game based around music, consisting of twenty-five nearly identical tracks, none of which are the least bit memorable and made having to listen to them dozens of times per level immensely irritating.

Though it blends two of my favorite genres (music and puzzle games), Circuits manages nothing but to be exceedingly unenjoyable in nearly every aspect of its designing, failing to even deliver upon its original goals as it meanders about with uneasy steps in its mess of dismal design choices. I'm not sure why I bothered to push through to the end, as having done so I can see I was having very much the same experience then as right at the start of the game, which is to say a dreadful time that I couldn't recommend to others.

Circuits is essentially a music puzzle game, where you get to reconstruct melodies by putting little sound hubs in their right positions to build a track. The game mechanic is based on you listening to certain melodies and then identiying the proper sounds and putting them in the right order. Note that you will probably have to listen to some parts repeatedly to get them right, since it is something not everyone has the patience for.

The difficulty is generally not high, except towards the end (levels 24-25). You can, however, choose to *not* break up the music into layers in the previous levels, so it will be harder for you to distinguish the different sounds playing at the same time. The game is a tad short, I finished it in roughly 4 hours, but that can vary depending on the person. However, the developers have promised more levels in the near future, so this might change.

Overall, I would say that circuits is worth your time. It is simple, yet elegant and relaxing if you are generally musically inclined. It is hard to comment beyond personal preferences for this type of game, since I feel it is mostly a matter of taste, so if you think what I have mentioned so far is something you will like, you will probably enjoy this game as I have.

Circuits has nothing to do with electricity, but it does require a good musical ear to distinguish sometimes subtle differences in sound samples. And that's basically what circuits is all about--chaining musical samples together to reproduce the default piece of each level. While the music samples are pretty good, as a game where the player simply tries to reproduce what he hears, I didn't find it all that fun or engaging.

As I played the game, I was thinking that the user should be able to make his own musical scores based on the samples provided. And apparently there is a Circuits Composer feature coming soon which I think will make this game a fun little music generator. So I give it a thumbs up for a future unreleased feature. The base game isn't all that impressive, but it's hard not to recommend it given the sale price.

Circuits is a music puzzle game where you match the sounds of individual tracks in the appropriate course of the "circuit." Ultimately, the game is a test is your aural detection and mimicry, and not much else.

While the game is titled Circuits, the gameplay relates to circuitry in only a superficial (using the symbol for ground, etc) manner - there is no actual relation to circuit design (ANDing or ORing the audio signals, for example) in order to create the music, which is somewhat disappointing. In each level, you are given a series of tiles each of which contain a single musical track. Along the progress bar of the "circuit", there are locations where you drop those tiles in order to match them to the given audio track. Sometimes you'll have to loop individual tracks or groups of tracks, and there are "switch"es where you choose one track over another, but in truth they only serve to make the levels easier, as the tiles are in fixed locations on them, which limits the areas those tiles can be used.

Ultimately, this is a game of mimicry/memory. The last couple levels provide some degree of challenge within that constraint, but for the most part I didn't find the game particularly challenging/fun. The music itself was generally pleasant, and if there was something more to the game than "match what you hear" I would probably switch this to a recommend. But as is, I don't think most people would overly enjoy the game - if a game of matching audio tracks to one another sounds like fun, then by all means.

I'd recommend not splitting the layers in order to provide a higher level of difficulty - you'll probably get more out of it.

Very well-designed, minimalistic and, as stated in a description, extemely rewarding.
In general, making epic songs from small parts and seing them work as intended and with precise rhythm makes you get an "Eargasm" (just like the name of one achievement in Circuits).
Just put on your headphones, relax, listen to music and ♥♥♥ from your ears)

Circuits is an outstanding puzzle game that is sure to immerse any player who chooses to experience its sheer brilliance, with its only major problem being the length. Combining colourful and radiant visuals with an exceptional, contemporary soundtrack that both impresses and excites players, this is one of the finest puzzle games that you will play – not because its difficult (which depends on the player’s knowledge of music theory), but because it is an immersing, profound experience that is equally as rewarding as it is exhilarating.Given the low price offered on multiple platforms, it seems it is just not a bad deal.Circuits is an immersing and profound experience.

PLEASE NOTE: this game has nothing to do with electronics, wiring, or circuitry-- it's a music game! Who knew?

Actually, it's a *fantastic* little indie music game great for any musician, person with musical talent, or even anybody who just wants to improve his/her musical ear. The "circuits" are just the visual manifestation of how the music plays out-- pay no heed-- it will make sense once you try the game.

Basically, you listen to some synth music, and with your ear (assisted by optional in-game hints), figure out which chords go where in the progression; which sections are looped (and how much), what the beat patterns are (and how they are repeated). I don't consider myself a huge fan of techno/synth/trance (some of it I like), but I found all of the music pleasant to listen to.

There are 25 levels-- whether it's a long game or a short game is completely based on how you are able to figure out the levels. For achievement-hunters, if you have a great ear (or don't mind using some in-game or Steam Guide hints), you can 100% it with relative ease...there's nothing unreasonable.

I bought it "on sale" for $1.19, but it's only $3...less than a coffee-- and it has trading cards you can sell or use. Give it a try and support these indie devs. I'm just hoping for a Circuits 2!

[Edit: One more thing: if you like the music, the soundtrack is available as MP3s in your game folder, which is something like C:\Program Files (x86)\Steam\steamapps\common\Circuits\OST.]

Puzzle for the audio lovers.
You play a sample song, then recreate it, using samples, as puzzle piece.
Yes, simple and straightforward.

You'll need to have a good ears and good musical sense tho.
But hey, this game is fun even if you didn't!
Just put on your headphones, and listen, and solve the puzzle.

9/10 great sound and music.

Circuits is an independent masterpiece. It is highly original, and I have never seen another game like it! While it's mechanics are deceitfully simple, you will come to find Circuits both stimulating and satisfying. The objective is to string together various segments of a song in the correct order... Easy, right? =)

Story: If you only play games with a primary focus on storytelling, Circuits might not be the game for you. If you can, however, enjoy a game without a tale to tell, I really implore you to try this game.

Gameplay: If you are a music lover, this game might suit you. The gameplay revolves around the music, and I assure you that the soundtrack is superb, and with good reason. Basically, all you have to do is listen to the song and figure out how to recreate it on an empty template. You can listen to the song in layers, or as a whole, depending on how well you can pick apart sound. The game doesn't take long to beat, and my only complaint is the difficulty. It starts off extremely easy, and at some point takes a leap into higher difficulties. Overall, this game is extremely enjoyable, especially if you're just looking for something relaxing to do.

Controls: This game offers an untraditional approach to gaming. While the controls are simple enough, and playable simply with a mouse, it is best played with a set of headphones. This helps the player to become immersed in the sounds, which in turn will aid them on their quest to put the sounds in the correct sequence.

Graphics: Sleek, simple, and to the point: Circuit's interface is highly appealing, and not overly cluttered. The music will be threaded together on a maze of lines, taking the form of colourful circles, which will light up as they are played. The background is subtle, and overall, I feel that the graphics are reasonable.

Sound: The audio is possibly Circuit's best selling feature, in my opinion. While some sounds are not entirely appealing, most are incredibly easy to listen to. It is easy on the ears, and progresses in difficulty throughout the players gaming experience. There isn't a lot left to critique.

Replay Value: I'd be willing to play Circuits again, I'm kind of a sucker for puzzle games, so I tend to play a puzzle per week, or so.

Very nice and clean. You will love it if you are a musician but you'll hate it if you have absolutely no musical ear (as the whole gameplay is based on that). The only annoying thing is the fact that you play only with the mouse. There is two play modes (one for the music you have to reconstruct and one for what you have reconstructed yet) so you always have to move the cursor and click on play buttons and layers buttons that are apart from each other. With such a simple gameplay, it would have been easy to add keyboard shortcuts (spacebar?) for play modes, and 1,2,3,4 keys for layers. That's the only tiny thing missing from this game.

Gameplay tip :
Reconstruct each songs layer by layer before listening to the whole thing, it gaved me more eargasms to discover the song after reconstructing it. It feels more like you've made it instead of just copying it.

Recommended *at sale price*.

Pretty cool. It's definately worth it for the sale price and if you like ambient music and ear training exercises. Also good as a calming game in the evening.

What would send this game from "neat" to "awesome" would be a 'level editor' where you could make your own sound bites from the samples you unlock in the game. However, I am not sure where this would fall in regards to copyrights.

Circuits in it's basic form is a puzzle game, put the correct piece in the correct spot and see if everything looks right. However, what it does differently is every piece of the puzzle is a short piece of music, which you need to put into the correct position to recreate the whole score for the level. You might think this is quite simplistic, but if you are not a very musically driven person like me, it may be somewhat difficult to differ which piece goes where, due to some of them sounding very similar. The game slowly introduces different mechanics like layers, looping and switches, which increases the difficulty if you don't listen carefully.
All in all this simplistic game is a very cheap gem on the steam store that forces you to listen to be able to solve the puzzle instead of staring and observing like many other games but can still be quite challenging and time consuming, although time is not wasted when you finally get to hear the masterpiece you put together.

For a game that relies entirely on its music, the music is horrible. Other than the two final levels, every other song is a bunch of electronic crap.

The ultra-simplistic "gameplay" offers barely any variety and depth and thus Circuits quickly becomes boring.

Every few stages, a new gimick is introduced, which makes the game slightly harder. Except for the two final levels, where the ability to listen to only certain instruments (which helps a lot with beating levels) is suddenly removed. This turns the final levels into awfully frustrating and tedious annyoances rather than challenging levels.

Should have just been a free flash game.

At first glance Circuits looks like a nicely designed music puzzle game, but when you hear it... time stops. Its soundtrack is absolutely magnificent and often feels too good for such a simple gameplay mechanic. As a result the game overachieves in what it does, and completing each puzzle couldn't feel any more engaging. It may require having an ear for music to fully appreciate it, as the puzzles become too subtle closer to the end, but whether you have it or not, Circuits will make you forget about the time, leave you wishing for more and inspire your creativity.

Original musical puzzlegame

This is an extremely original game, very well executed and polished. It's all about listening carefully to short musical examples (which are quite well made actually) and trying to re-compose them. To this purpose you get several original tools: you can listen to the music layer-by-layer (for example, strings only, or bass only), and you get snippets of music which you can place in their appropriate place on the timeline.
Could sound very demanding and even baffling, but it's very well executed, and the difficulty level goes very slowly up. Still, you need good ears - the ability to recognize different pitches and rhythms, at the very least.
So this is probably not a game for just everybody, but for those who want a game with some artistic claims, and want to enjoy playing around with music, this is a real treat. And yes, the graphics are very good: functional, but oh so artistic. Playing a game like this, I realized once more that games really are art, sometimes (and more and more often with all these indie-talents of recent years).

Gameplay: 24/30 (it's very satisfying to finish a new level)
Graphics: 14/20 (functional, static, but oh so beautiful)
Sound: 9/10 (best enjoyed with good headphones!)
Replayability: 12/20 (it's quite a challenge to complete the levels, but once done, it's done)
Stability: 18/20

Overall: 77/100

Preface: this isn't a bad game audio jigsaw puzzle. I want to really like it... I'm glad to see a music game out there... but there's just not much to it. It's a cool little toy, but I wouldn't really recommend it to someone.
