Start with an action, not a bigger rectangle
A useful way to choose a Duo game is to finish this sentence: when I fold the phone, the game does what? A concrete answer is more informative than a broad promise of optimization. In some games the hinge changes the puzzle; in others it organizes your cards or controls. Both can be worthwhile, but they are different experiences.
This selection is based on current developer descriptions and our source records. We have not performed hands-on performance tests. Screenshots marked as Duo artwork come from the developer’s App Store listing; ordinary iPhone or iPad screenshots are labelled separately.
Orisuji: change the maze by folding the page
Orisuji treats a fold as a change to the puzzle board. Its developer describes a paper maze whose two pages combine when the phone closes, with play continuing on the cover display. The idea makes the transition between the inside and outside of the phone part of the problem you are solving.
The trailer below is from the game’s own channel, not an independent review. Watch for the sequence of open board, closing movement and combined maze. That is the useful distinction from a game that simply occupies a larger screen.

Hingami and Marbles Unhinged: a crease or a changing floor
Hingami maps its paper-folding theme to the hinge. The store artwork includes a dedicated “Even better on iPhone Duo” panel. It is a good starting idea for someone who likes careful, small moves and a familiar origami metaphor.
Marbles Unhinged takes a different route: its developer describes a maze affected by tilting and folding. Rather than assume both games feel alike because they use the hinge, choose between lining up a paper crease and controlling a moving ball.
Toastie: close the lid on a very small kitchen
Toastie uses an everyday object as the explanation for its controls: the phone is the sandwich press. The developer describes preparing a sandwich and closing the Duo to toast it. It is an easy concept to share with someone seeing a foldable game for the first time.
Choose it for the cooking premise and physical joke. Check its current store price before downloading, and use normal, gentle closing movements. A game mechanic is not a reason to slam the device.
FleetFold: the fold gives two grids separate jobs
FleetFold is a useful counterexample to the idea that every interesting Duo game needs constant opening and closing. Its store artwork explicitly shows a Duo arrangement. Separating your fleet from the target waters gives each part of the display a clear role.
If you prefer turn-based decisions to motion controls, start with a tabletop layout. If you want your physical movement to change the rules, start with a fold-controlled puzzle. The right choice is the one you want to keep playing after the novelty passes.
