Folio is a book of logic puzzles that never runs out.

SIX KINDS OF PUZZLE
• Kings: place one crown in every row, column and colour region, with no
two crowns touching.
• Shikaku: split the grid into rectangles, each holding one number equal
to its size.
• Pipes: turn the tiles until every pipe connects into one network.
• Snap: draw one path through the numbers in order that covers every
cell.
• Mosaic: each number counts the dark cells around it. Fill them in to
reveal a picture.
• Tower: crack the hidden colour code in as few guesses as you can.

Every puzzle has exactly one answer and can be solved by logic alone.
No guessing, ever.

ENDLESS QUESTS
Every puzzle has its own quest: a winding road of stages that starts
gentle and grows into full-size Hard grids. Clear a stage to open the
next. Every stage is a fresh puzzle, and the road never ends.

one.

carries it to a new phone.
