Player Experience Highlights

Community Insight:

Im an audio engineer, and love the gamification of solving the routing puzzles which feels very much like the real thing sometimes! Great UI too! Its so satisfying just to plug in all the cables.


We laughed when we found out this thing existed. The cable physics are identical to that of software modular patch bays. Love this. XD.


Really helps you think about what goes where. If we had one wish it would be for other components and cable types. Great app.


Whether you are new sound tech or experienced this game will stretch your thinking.


Challenging, addicting, unique… As a musician we thoroughly enjoy the style and layout of this game … Very trendy.


We are a live audio engineer. This is our new addiction.


If we could patch to our music collection with this app, we wouldn't stop playing it. At first we didn't want to cross L and R RCA. Then we realized You need to. We spent the 2 bucks with pleasure.


Where's the cable management. How bout some cable ties? Jk great game for nerds.


We have to admit to making a few of these rat's nest patch jobs in our real life :D.


We are a sound producer and we were looking for audio apps for our iPad Pro, and this game came up. We wanted to try it and we love the puzzle prospective it gives you, but yet still associating with sound. We haven't been able to stop playing it yet. We have noticed one small glitch though. Whenever you get asked to buy the rest of the levels after the 40th level, it doesn't require you to pay. It just gives it to you. Hopefully you developers can fix this soon so they can be supported to continue on this amazing game.


You get 40 levels for free. Which is awesome because it was a fun game. Bad because when you purchase you get up to level 100. Sooo, we guess we're done with this game.


Being an Audio guy very fun game to play! It's very very addictive and challenging at the same time.


Not only is it fun, it's a great way to teach newbs signal flow.


As an audio engineer it's always fun to see cool little games like this get made. This game rocks can't wait till there's more puzzles.


Suuuuuuch a good game! Brilliant in its simplicity yet challenging, this game will keep you coming back for a quick round over and over.


Our daughter and we love playing the game together. It is a simple concept but very challenging as you move up levels.


One of the best puzzle games we've played in a while. We really enjoyed it.


It's such a breath of fresh air to find a puzzle app with a unique game mechanic. This one is all new, and all fun. Brilliantly designed to create an engaging and invigorating brain teaser. Perfect for those who like to think.


A really fun game. Concept is great and it plays very smoothly. Great job, guys.


We usually don't review games but we loved it so much that we recommend it in real life all the time, so…here we are leaving a review. Easy on the eyes, tons of levels, and the puzzles felt challenging.


We love this game! It's a great concept, beautifully realized. No ads, nice graphics. A brilliantly straight-forward puzzle game. We don't understand why there's so much talk about level 24. It isn't any more difficult than the previous levels. It's very straight forward. No worries. The puzzles become more complicated, but still easy enough to be relaxing up level 58. Level 58 seemed impossible. We finally figured out the answer, but it took about 20 mins.


Fun puzzles, great way to chill out.


We really loved this game ! It's not that hard!!! We swear we have been win this game after we download It, And after 3 or 4 days we reached level 80! It was COOL, can you please do more levels.


Hoping for harder puzzles soon. This is a great quick puzzler.


Really hope for some expansion. Beat the entire game in 2 days. Absolutely enjoyed it.


We're not a gamer and we loved this! We totally agree with other reviewers: we would gladly pay for additional levels.


Love the game. We recommend it to anyone who loves logic puzzles. We'd love it more if there was a hint feature or a way to skip a level.


We want to start off by saying that this is a great puzzle game. We just can't get past level 58. We swear we have tried everything, but we don't get it? We've had little to no trouble with the previous levels; this one has us stumped, please help.


Very fun and satisfying little game, but we wish there were more levels! It was over much too quickly. There were some challenging levels, but none that took us more than a few minutes to figure out.


Loved this game from the beginning. Just the right level of toughness and fun. Was stuck on lvl 58 for over a day.


This game has a clever mechanic and starts to get interesting about 20 levels in. We've finished all 80 levels and would gladly play another 80! Or perhaps a level editor would be enjoyable.


We love this game and we hope they make more levels soon. Some on the levels are hard but then you realize you were making it way more complicated than it had to be. This game is awesome.


So much fun!! All levels are beatable.


As an Audio Engineer, this is such a cool app! Very addicting, so beware.


This game is off the chain! It makes a puzzle out of hooking up stereo and sound equipment. How cool is that! It is challenging though and very fun! We've already finished the game and we hope the developer makes more levels. We would pay for another level pack.


As a musician & sound engineer, this game made our life impossible. Thanks a lot LOL However, we finished this game in a day… Got us wanting more. Please update ASAP.


This game is wonderful for multiple reasons, no in app purchases and a fun little game also, has innovative mechanics.


We love this game, logical puzzles… Wonderful! Our only issue is that the game is too short. But over all the game was very enjoyable, thank you.


This game is super addicting and really fun to pass the time. It's a great game for those who like problem solving or just like puzzles.


We just picked this game up from the App Store this evening and we haven't put it down. One of our new obsessions! We would recommend this game to anyone! Also, to fellow strugglers on level 24. We had a hard time figuring it out, but after a while the solution just jumped out at us. You will feel dumb once you see it, we promise. Just remember that the red round ports can connect to the normal white round ports.


Just downloaded it and finished in 2 days. Perfect for the signal flow junkie! Hopefully there will be a new version soon.


Finally a game for pro audio geeks! Love it.


Our only problem with this game is that we already finished it and want more.


We're not sure what people are complaining about when it comes to level 24. We found it very easy and finished it within 60 seconds or so, and we're on level 42 now. Fun puzzle game, worth getting.


We love this but we're stuck on 58! It's impossible!@$&.


Finished all 80 levels in a couple of hours. Fun & enjoyable brain-teaser. We hope more levels will be added in the future.


Love it, but can't get pass level 79.


If you boil it down, it is a simple logic game. Remember that you don't have to always work top down, nor do you have to use all connections to win. Object is to power the amp, not use up as much cable as possible.


We beat this game within 7 hours of downloading this game, it was a lot of fun and can't wait for the festival, just can you guys translate the email sent out for everyone, it's completely in the Swedish language, so we can't understand any of it thanks.


If you like this kind of puzzle, it's highly recommended. Challenging without being completely insane, and if you complete it, you can enter to win tickets to the B-Side fest. The quality is especially surprising as its a free game built to promote a concert festival. Little to no marketing in it, so you really can't go wrong, here.
