Star Battle (also known as "Two Not Touch") is a challenging logic puzzle. Place two stars in every row, in every column, and in every region, but make sure that the stars do not touch! Each puzzle has only one solution, which can be reached with logic reasoning, no guessing needed!

Solve these logic puzzles to challenge yourself, to relax, to train your brain, or to kill some time. This puzzle provides hours of challenging entertainment! With puzzles ranging from easy to fiendish, it offers something for both beginners and experts.

Star Battle can be classified as an object placement puzzle, like Battleship or Trees and Tents, and a binary determination puzzle, like Hitori or Nurikabe. Users often refer to it as a nice cross between Sudoku and Minesweeper.

These logic puzzles can be pretty tricky and it might take some time to learn how to solve them. The app includes a "How to Play" to explain the solving strategies and you can always ask for a hint if you are stuck. You can also check at any time if your solution is correct so far.
