How to play

Take turns dropping discs into the board. The first to line up four of their colour across, up and down, or on a diagonal wins. Drag across the board to aim, and let go to drop. After a game, tap the board or Play again.

Common questions

How do two people play on one iPhone Duo?: Choose Two sides and turn on Outside screen. Stand the phone up like a book, board half facing you. Your opponent sits across the table and plays on the outer screen, seeing the board from behind, like a real one. You can also stand it like a laptop with the board half upright.
Why does the outside screen need the camera?: iOS only lets an open iPhone Duo show an app on its outer screen while the camera is in use. Fourfold throws every frame away without looking at it, and records nothing. See the privacy policy.
The outside screen won't come on.: Check that camera access is on in Settings › Fourfold, that the phone is fully open, and that seating is set to Two sides. If it still won't, choose One side and pass the phone.
Can I play on another iPhone?: Yes. On any iPhone you can play pass-and-play, against the phone, or the puzzles. Closing an iPhone Duo moves the game to the outer screen.
How do the puzzles work?: Close your iPhone Duo and tap Puzzles on the outer screen (on other iPhones, choose Puzzles next to the other modes). Win in the number of moves shown while the phone defends. Hint lights the winning column, the arrows skip between puzzles, and your progress is saved.
How do I change the look?: Tap a skin: Classic, Neon, Candy, Walnut or Cosmos. Each has its own discs, drop, sounds and celebration.
How do I reset the score?: Tap Reset scores under the panel (it asks first), or press and hold the score cards.
