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.) ■
