About this game

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.

Are you up for the challenge? Can you solve them all?

One of the few times I've decided to rate an app without being prompted. I love this game. I am not an intense puzzler; I'm playing on easy, and that's plenty of challenge for me. If (like me) you're staring at this page trying to figure out what the game actually is - it's like sudoku but with more variety. I would describe the overall design of the game as friendly. I love the seperate hint and error check systems. The ads are not intrusive. Amazing all around and I'm addicted.

Nicely done. Easy and medium puzzles are challenging but logic helps you learn how to mark patterns. I could solve the puzzles faster as I got better. The difficult ones are doable but take too long. They require more trial and error or looking farther ahead. Ads aren't too bad. Suggestion for developers: allow users to mark a square to come back to if they try something then realize they've made an error. Reversing via the back button works but you have to remember where to stop.

Fun puzzle game that does monetization right, pay for removing ads that aren't very intrusive and additional content. Hints teach you how to play and a check feature let's you make sure the logic you just used was sound. Difficulty jumps can seem like a lot but once you learn a new trick or two it settles back down quickly.
