While a lot of games on mobile try to replicate more control schemes with digital d-pads and buttons and virtual steering wheels and so on, others go the opposite route, using the tactile nature and portability of mobile devices to great effect. The Room, Shadowmatic, and Monument Valley let you play with, push, twist objects. Zombies, Run! tracks you location through GPS. Device 6 had you rotating your device to follow the twists and turns of its word-corridors. And now, the enigmatic puzzler Blackbox presents you with conundrums that could only be done on a mobile device.
What that means is that your phone is quite literally transformed into a puzzle box. Solving a puzzle is an exercise in experimentation, rotating and turning your device, interacting with exterior various switches and buttons, using specific features like the camera, or even making noise into the microphone. Some puzzles may take multiple sessions to fully complete, or require you to return to the game at different times, or when your phone is in a certain state.
Blackbox is free to download, with an optional $1.99 hard level pack available, and more levels to come in the future. If you're interested in learning more about Blackbox, the developer wrote an informative Medium post regarding the game's creation and future.
