Fold &Flip
Book cricket and book basketball for iPhone, built for the iPhone Duo hinge.
Open the phone, a page appears, and the last digit of the page number is the outcome. Fold it again for the next ball. On a regular iPhone you riffle the fore-edge with your thumb instead.

How it plays
- 1
Open
Close the phone, then open it. How far and how fast it opens picks the page, revealed once the book is fully open.
- 2
Read
The last digit of the page number is the outcome: of the ball in cricket, of the possession in basketball.
- 3

Fold it again for the next ball. On any other iPhone, swipe or tap the fore-edge to riffle the pages.
Screens

Three books
A thin comic, a paperback and a thick hardcover. Each has its own page count, dead pages and haptic feel, which is what makes them play differently.
Skill, optionally.
Same fold, same page. With skill on, the page is set by how far and how fast you open the phone, and it stays consistent for the whole match, so you can learn a book. Each new match shifts the book.
Off for Daily Flip, so everyone plays the same sequence.
