Katachi Puzzles

Turn it. See it. Connect it. Katachi Puzzles offers four logic puzzle collections on 3D surfaces. SURFACE LOOP Each number tells you how many lines surround its cell. Draw one unbroken loop across faces and edges, with no branches or crossings. Explore cubes and polyhedra with triangular, pentagonal, and hexagonal faces. Clues remain upright as you rotate the board. SKY BRIDGES Match each island's count with single or double bridges and connect every island. Bridges cross floors and climb between them. Explore two- and three-story boards in 3D or in floor plans. COLOR PATHS Connect matching colored dots while using every cell. Paths must not cross or branch. Trace matching colored lines around cubes and octahedra, on boards of up to 128 cells. SEA & ISLANDS Shape white islands of the indicated size and one connected black sea. Separate islands must not share an edge. Leave a white cell wherever cell corners meet, including the three cells at a cube corner. Discover larger island shapes on boards of up to 150 cells.
