Constellations - Star Sudoku

A zen star sudoku: place the stars, reveal your own constellation.

A sky to piece together, a logic to crack.

Constellations is a Sudoku-style logic puzzle: place exactly one star per row, column, and colored region - with no two stars ever touching, not even diagonally. Solve a level, and it reveals its own constellation, drawn just for you.

HOW TO PLAY • Exactly one star per row, column, and colored zone. • No two stars can touch, not even diagonally. • Tap once to mark a cross (eliminate a cell); tap twice to place a star. • Every level starts with one free star already placed to get you going. • A few mistakes are allowed each level before you'll need to try again.
