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.

(Blackbox is a living game under active development by Ryan McLeod. When not eating burritos or drinking coffee, he’s busy designing and developing new Blackbox challenges.)

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.

It is definitely not your average "mind game". This game might actually help people to find out some extra features of their device (although, I already know all the features used by the game)

Edit: If the App Store supported crossing out words, then that last in parentheses would be. This game receives regular updates and more challenges. I wish games of this level of quality, care and character were more abundant on the App Store and elsewhere. I don’t like spending money on in-game purchases just for a game, but I do like using my money to support developers that deserve money for awesome and thoughtful games like Black box. I try to make sure that developers like the creator of Blackbox can keep developing games like this and I hope that more developers with similar levels of care, creativity, and outside the box thinking (pun partially intended) start to come out into the light. Also, I think helping people discover the functions of our high-tech phones along with just having this game use every facet of things built into them to solve these challenges is awesome. Especially since this game is not necessarily designed as a discovery game for phone functions but as instead an “everything goes” (within the physical possibilities of our phone) type puzzle. And I love every bit of it.

Developer Response ,

I love every bit of this review. Thanks so much for the kind words and support. Supporting your favorite indie devs really is the best way to see more apps like Blackbox on the App Store :)

Lonely in Los Angeles

I have an unhealthy relationship with this game. It started out like any affair, fun and exciting and so brand new. Then, things changed. I wanted to know more, but Blackbox was out of love to give. We grew apart. Now, we’re on-again-off-again. Every few months, out of the blue, it shows up on my doorstep, asking me to play. I oblige. It stays a while, asks for money, and leaves me again. I don’t hear from it for months: no phone calls, no letters, no push notifications. I’m left alone and empty, lost in a world without challenge or intrigue. The days go by, and I find myself mindlessly doing crosswords, numbing myself with endless spider solitaire, and crying over App Store disappointments; I download and delete over and over again, cursing each app that promises what only Blackbox can deliver. Maybe someday, when we’re older, Blackbox will settle down and we can have a committed relationship. Until then, I wait for it to call on me. I know when it returns I should say no. I should look for a more traditional game, maybe I could be happy...but I guess I’m just a glutton for puzzlement.
