Uphill Duo
The arcade game made for iPhone Duo. Stand your Duo up like a laptop and its hinge becomes the ramp: the flat half is the lane, the raised half is the ramp, and how far you fold the lid sets how steep it is.
Flick the ball up the lane, over the crease and up the ramp, and drop it into the pockets. The 100s sit in the top corners. Fold the lid steeper for harder rolls and a bigger score multiplier, up to ×2.4. Nine balls a game.
Uphill fits every way you hold a Duo: standing like a laptop, open flat, sideways like a book, or closed on the outer screen. On any other iPhone, a slider sets the slope.
No accounts, no ads, no tracking, and nothing leaves your phone.
