Photo jigsaws, split into two halves for two players on the open Duo
Does Jigsaw: Photo Puzzle Maker work on iPhone Duo?
Yes, seen running in the iPhone Duo simulator: closed, the board sits above the loose pieces; open, the picture splits into two halves for two players.
- Simulator verifiedMusicFlow, on its website, showing Jigsaw in the iPhone Duo simulator: the board on the cover and the two-player layout open. The App Store notes also mention the Duo; the seller is Haruhiko Kishi, and the listing links back to MusicFlow.
Adapted for the fold
- Closed · Outer display
One board on the cover
On the cover, the picture sits above the loose pieces, with the controls and status at the side.
- Open · Inner display
One half each
The book button splits the picture into two halves, with loose pieces on both outer sides. The maker says some pieces start on the other side, to be passed between players.
About Jigsaw: Photo Puzzle Maker
Jigsaw makes puzzles from your photos. On the open Duo, the book button splits the picture so two people side by side can each solve half; closed, the board sits above the loose pieces.
MusicFlow also describes keeping resting pieces away from the fold when the phone is half-folded. Version 1.3.5, released October 13, adds a home-screen layout for the half-folded phone and a larger photo preview with the cover held in landscape; those screens aren’t in the simulator pictures.

Looked at the three Duo images on the maker's site: the cover has a board above loose pieces; the open two-player view has separate picture halves with pieces at both sides; the other open image has the board on the left and loose pieces on the right.
Poses shown: Closed, Open. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence. Environment: Maker-provided iPhone Duo simulator screenshots.
The screenshots show no app version or bent device frame. No build or physical device tested. The rotated two-player image in the note.com post is an iPad capture, so it was not used to verify Duo support.
