iPhone Screenshots


So you think you understand this thing you’re holding? Think again. Stop tapping. Stop swiping. In fact, stop touching the screen at all. To crack Blackbox’s puzzles you’ll need to find solitude and stillness, climb mountains, call on friends, get in tune with the cosmos, and think outside the box.

Minimalistic visual clues make for incredibly satisfying “Aha!” moments, while sonic interfaces provide an extra level of guidance and nuance that makes Blackbox accessible with or without vision. Thoughtful haptic feedback, Easter eggs on Easter eggs, and solutions that can’t be found beneath the glass of your screen redefine what a puzzle can be. You’ll never see your device the same way again.

Think you’re clever? Prove it.

Previously on Blackbox Release Notes…
I know it’s been awhile but bear with me. Your humble developer is moving irl and my whole life is currently in boxes… *badum chhh* Oh also you might have noticed that the listed app developer of Blackbox is now Grow Pixel: a monolithic global gaming studio consisting solely of Ryan McLeod. #taxes Okay, go ahead, throw your tomatoes now and get it out of your system because this release contains mostly bug fixes but lays the groundwork some some interesting things to come—I promise.

“You’re lazy we get it… So what did you fix?”
■ I finally made the end-of-game feature iPhone X compatible. Like you even know what that means though…
■ I fixed a bug that could sometimes cause audio engine restart thrashing after playing one of two mic based challenges. Yikes.
■ I removed the label showing the number of unlocked icons in the alternate icon picker unless all icons are unlocked. Hopefully this reduces apoplexy over seemingly “missing” alternate icons.
■ I loosened the tolerances on a certain early game challenge
■ I added a new Combo Level Pack option to buy both paid level packs at once for a big hint credit bonus. The level packs also got some fresh new App Store icons!
■ I added some haptics to QR based challenges
■ I added some clarifying messages to QR based challenges
■ I changed some of the words in the things

“…that seems acceptable for now. So what’s still a problem?”
■ Well the alternate icon picker scrolling still isn’t perfect. Sometimes it appears to get stuck and dismisses itself in the blink of an eye.
■ Also the challenge to home grid transition is smoother now but sometimes looks funny.
■ Oh and where I’m moving to irl doesn’t have California burritos…

Editors’ Notes

The most ingenious thing about Blackbox's puzzles isn’t that you solve them without tapping or swiping. It’s that you’ll happily spend hours figuring out the game's subtle clues. Do you need to tilt your iPhone, shout into the speaker, or something a lot trickier? Thinking creatively and finding the answer feels deeply rewarding, even profound—earning Blackbox an Apple Design Award.

My Favorite iOS Game!


Blackbox is my favorite game that is currently on my phone. It's innovative, challenging, and funny. I think that some of the levels are a little bit too difficult, for example the level where you have to go a certain distance to turn on each of the four lights. I would prefer it if the distance was not so far, because I drove about 54 miles (~1 hour 15 mins) and only reached the second light. The speed at which the distance indicator advances only gets slower as well. I also live at a fairly high elevation, and I have not even reached the first light yet on the erudite pack level in which you must increase your phone's elevation to turn on the lights. I understand that these levels are meant to be challenging, but many people don't have the funds to travel such long distances or to travel to where there are very high elevations. Other than those two levels, I have found this game very enjoyable (although frustrating at times) and I get excited every time I see a new meta challenge has come out. Thank you Mr. McLeod for this wonderful game!

Thank you N00bRosie! I definitely plan to continue to release new levels and am looking into tweaking the ones you mentioned. Stay tuned and thanks for the kind review. You can always reach me at ryan@growpixel.com if you have further ideas or thoughts!

Interesting, difficult, and a bit creepy


I have to say this is a very interesting little game and it certainly makes you think. It makes you use your device in ways you wouldn't normally think to use it. My only big issue with this game is that some of the challenges are incredibly difficult. I won't spoil any of the game (you can find many walkthroughs online if you'd rather cheat your way through) but for some of the challenges you have to do things you would never think to even attempt trying. You know it's hard when even a walkthrough has to write two paragraphs on how to solve one of the problems. All that said, I do enjoy this game and wish there were many more free puzzles available at once. It is a big creepy, though, seeing just how much an application knows about what you do on your phone/tablet without giving it permission, like viewing your notes, homescreen, etc.

This game would earn a solid 5 stars if not for the insanely difficult puzzles, which, thankfully, don't make up all of them. I'd definitely recommend this to a friend.

Developer Response

Hey CinnamonFeet! Sorry for the slow reply. Just FYI apps can't see what's on your home screen or in your notes :) I do love to help show people via the game what apps do and might access to though. Would love to hear which puzzles your find too difficult and if you found the hints helpful enough. Always looking to improve… I'm at ryan@growpixel.com
