Constellations is a strategic logic game where your goal is to place one star in every row, column, and color region. The challenge is that no two stars can touch each other, not even diagonally, so you’ll need to think ahead and carefully plan your moves. It’s all about using logic and narrowing down the possibilities until everything fits just right.

To play, tap a cell once to place a cross (marking a spot where a star can't go), tap again to place a star, and tap a third time to clear it. You can also swipe across the grid to quickly mark or clear multiple cells. Once you place a star, crosses will be automatically added around it (though you can turn this off in the Settings if you prefer). And if you ever get stuck, don’t worry—unlimited hints are available. Just take your time, stay strategic, and enjoy the puzzle!
