About this game

Kuromasu is a challenging logic puzzle. The goal is to find the black fields on a grid with numbers, where a number indicates how many white fields this number can "see" in horizontal and vertical directions, while black fields block the view. Be careful though, black fields cannot be next to each other, and all white fields must remain connected to each other! 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.

Kuromasu is a binary determination puzzle, like Hitori or Nurikabe, but it has also similarities with object placement puzzles like Battleships or Star Battle (Two not Touch).

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?

A brilliant logical puzzle game with a great user interface and unobtrusive ads. Hundreds of different layouts to attempts, ranked into four difficulty levels, with a really useful "correct so far" function plus hints of you get completely stuck . Hours and hours of puzzling fun.

I absolutely adore this app and this game. The puzzles are uniquely challenging but super interesting to play. This developer has a history of making beautifully simple/easy to use puzzle apps with a surprisingly lot to work with - their Star Battle Puzzle, and Trees & Tents apps were already two of my favorites, and this is another fantastic rendition of this sort of puzzle. I love it! It's so fun:)
