  1. Greens on iPhone Duo

  3. Battlefleet Duo on iPhone Duo

    Brian Corrieri · Free

    Tabletop mode puts your fleet on the lower screen, with the enemy’s waters standing up in front of you.

    Full-screen mode uses the big display for richer 3D graphics and effects.

    Two players sit face to face, each with their own board.

    The camera and layout adapt as you fold the device.

  4. Marbles Unhinged on iPhone Duo

    Cromulent Labs · Free

    The two screens are two halves of one board.

    Bend the top half and its floor becomes a ramp; the steeper the fold, the faster the roll.

    Stand the top half up and bank the marble off it like a wall.

    Snap the hinge and the marble leaves the floor.

  2. Orisuji

    Adrien Friggeri · ₺249,99

    A paper maze you solve by folding: close the phone and the left page lands on the maze, bridging its holes.

    Unfold and the page lifts away, carrying whoever stood on it. Folded, the maze carries on on the cover screen.
