Papiko
A puzzle game for iPhone in which you fold a sheet of paper. You arrange colors, numbers, pixels or lines on the top half, then fold it over the bottom half. If the print matches the target, the puzzle is solved.
Yellow on blue makes green, yellow on red makes orange.
Four games, one idea
Whatever lies on the top half lands mirrored on the bottom half when you fold. Each game turns that into its own kind of puzzle, and each starts with a few short levels that teach it.
Drops
Drops of color sit on the top half, and a few blots are already on the bottom. When you fold, colors that meet mix. You move the top drops until the print matches the target exactly, in as few moves as you can.
Sums
There are numbers on both halves. When you fold, each top number is added to the bottom number it lands on. You swap top numbers until every bottom cell reaches its target sum.
Pixels
A nonogram: the numbers along the edges say how long the filled blocks in each row and column are. Every picture can be solved without guessing. When you fold it shut, it gets its colors and goes into your scrapbook.
Lines
You draw lines between dots on the top half. When you fold, they land mirrored on the bottom and, together with the lines already there, must form exactly the target picture, with no line missing and none extra.

Daily puzzles
Every day there is a Drops puzzle, a Sums puzzle and a Pixels picture, the same for every player. They are easy on Mondays and Tuesdays and hardest at the weekend.
Playing every day builds a streak. One skipped day a week is covered automatically, and a missed puzzle can be made up from the archive within two days.
mediumThe sky on your home screen
Each world you finish hangs a paper object in the sky above your home screen and sticks a stamp into your scrapbook. There are 16 worlds, so 16 objects. Tap one.

Stars and hints
Each solved level earns up to three stars. They collect in an account that pays for hints. The first hint in every level is free, and each hint explains why a move is right. Stars cannot be bought, and there are no lives to run out of.

On iPhone Duo
On iPhone Duo the crease of the sheet sits right in the hinge. To fold, you close the device, and the result appears on the outer display.
On every other iPhone you tap “Fold” or swipe the top half down. The puzzles are the same on every device.
