Foldfish is a free fishing game that you play by folding the iPhone Duo. You unfold the hinge to load your cast, tap to throw the line, and hold to reel in your catch while you dodge the other fish.
The game comes from developer Jan Poncik and is available on the App Store with optional in-app purchases. Version 1.0 launched this week, and version 1.0.2 added support for more than 30 languages.
The hinge works as the fishing rod and the open screen is the pond
There is no joystick in Foldfish, so the hinge itself works as the fishing rod. Unfolding the iPhone Duo loads the cast, a tap throws the line, and holding your finger down reels the fish in. The other fish in the pond keep moving, so you have to steer clear of them as you pull your catch toward you.
With the iPhone Duo open in book mode, the pond spreads across the entire inner display, and fish swim right across the fold. The pond changes from sunrise to starlight, and the game promises dozens of fish to hook along with a few surprises. The 7.6-inch inner display gives the pond plenty of width to fill, and the developer pitches the game as easy to pick up and satisfying to master.
Many older apps run in a safe area with a black background on the iPhone Duo. Foldfish is built for the foldable, so the water fills the screen instead.
Coin packs and Foldfish Gold are optional purchases
Foldfish is free to download, and the in-app purchases are all optional. Handful of Coins costs $0.99, Bucket of Coins costs $1.99, and Chest of Coins costs $3.99, while Foldfish Gold costs $3.99.
The game also plays on any other iPhone, where on-screen controls replace the fold. That means you can try it before an iPhone Duo is in your hands, or hand it to someone who has a regular iPhone.
Foldfish joins a growing group of games built around the hinge. Orisuji is a paper maze you solve by folding the phone, and Duometry asks you to match an angle with the hinge.
Foldfish is a 53.3 MB download for iPhone that needs iOS 18.0 or later and supports English plus 31 other languages, including Arabic, Czech, Greek, Hindi, Japanese and Vietnamese. The developer says the game collects no data.
