Pitile: Sleepy Stone Puzzle

Fit sleepy stones together and build a stone wall.
Pitile is a quiet logic puzzle where you pack stones into a board, guided by the clues along its rows and columns.

HOW TO PLAY
• Clues line the top and left edges of the board. Each clue shows a stone shape and a number: how many more squares of that shape belong in that row or column. Place a stone and the number drops by the squares it fills.
• A clue with squares left blinks a small arrow toward its row or column. A clue that is met rises with a gold mark.
• Carry the stones waiting at the foot of the wall onto the board. They snap to nearby squares.
• Tap a stone to pick it, and the clues switch to its shape and color. Tap it again to turn it 90 degrees.
• Fill every square so that every clue matches, and the wall is complete.
• Placed stones can be moved again, and the undo button takes back your last move.
• Stuck? Tap the light bulb and the spot for one of the biggest stones lights up.

NEW TO THE GAME?
In the first area, The First Nest, Koro the otter shows you how to carry and turn stones and how to read the clues, one step at a time. You can reread How to Play from the "?" button in Settings at any time.

WHAT MAKES IT TICK
Every board has exactly one solution. You can reason your way there from the numbers instead of guessing.
For example, a bar clue reading "2 sq" on a row means two squares of bar stones sit in that row: either one bar lying flat, or two upright bars that each cross the row. Think about how each stone can turn, check the column clues too, and narrow down where every stone can go.

A WORLD OF STONES
Koro the otter travels the world holding Nemu, a sleepy companion stone. From The First Nest through the Garden, Beach, Seabed, Volcano Peak, Hot Spring, Strata Cliffs, Mine, Cave and Snowy Peak to the Night Sky: across eleven areas, the scenery, the stones you meet and the music keep changing.
The stones you place smile, and when you solve a board, they drift off to sleep.
Pick any area you have visited on the map to replay its boards.

KORO AND NEMU'S STORY
The journey opens and closes with picture-book scenes. Each area has its own tale, and after every board Koro and Nemu talk it over. Their words float in letter by letter, with little voices.

STONE ALBUM
The Album has a shelf for each area. Reach a new area and the stones that live there join your shelves: 71 kinds, from the Anvil Stone and mossy garden stones to sea glass, ammonite fossils, jade and star stones. Each one comes with a one-line personality and a short read. The stones of the night sky are pure fantasy.
Now and then you meet a rare stone that looks a little different. The Album keeps it just as you met it, and each area shows how many rare stones you have found.
On each page, that area's song plays, and you can read its lyrics.
