What's New

What We In The Industry Call “Hot Fixes”™
• Missing some seasonal alternate icons? Check again.
• Icon picker looking wider than it is all? Not anymore.
• Icon picker’s dynamic type support have you down biggly? Tada.

Every two weeks Ryan regrets not releasing an update with bug fixes and performance enhancements. This is not one of those weeks. Crafted with love in San Luis Obispo, California …jk it’s mostly crafted with cursing.

What’s new?
Requires iOS 10+

• Icon Picker
Blackbox is already a game of achievements but here are some more I guess.

• New Modal Card Style
Very readable type, so hot right now.

• New Security Mechanism
Oh how deliciously vague. (*iOS developers hate him!*)

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
