## What is Katachi Puzzles?

Turn it. See it. Connect it.
Katachi Puzzles brings two logic puzzles into three dimensions.

CUBE LOOP
Each number tells you how many lines surround its cell. Connect the lines into one unbroken loop across all six faces of a cube, with no branches or crossings.
Rotate the cube freely, unfold it, or focus on one face at a time.

SKY BRIDGES
Connect every island into one network with single or double bridges, matching the number on each island.
Bridges reach across a floor and between floors. Explore two- and three-story puzzles in 3D or in floor plans.

START WITH 18 FREE PUZZLES
Each game has one Free Pack with 9 puzzles: 3 Beginner, 3 Intermediate, and 3 Advanced.
All 18 free puzzles are playable without making a purchase.
