Puzzles you solve without touching the screen, adapted to every pose of the Duo
Simulator verified: Shapes and Stories, Ryan McLeod's studio and the developer, in a submission to FoldHunt on October 17, 2026, saying the challenges and every part of the interface adapt to the iPhone Duo's poses, sometimes with new ways to play, ready for launch day. In an email that followed, Ryan said the Duo build has been tested extensively in the simulator. The press kit's iPhone Duo section (blackboxpuzzles.com) shows the game on a rendered Duo closed, open, half-folded and standing as a tent. Version 3.3 on the App Store (released October 22, 2026) says "Over 100 views were rebuilt so you can fold, stretch, rotate Blackbox all day long" but doesn't name the Duo.
