LogiBrain Hitori – Use your logical reasoning

[Game] LogiBrain Hitori

LogiBrain Hitori  Get rid of your paper Hitori, you won’t need it anymore!

Thousands of unique puzzles, 5 difficulty levels for beginners and pro players, 7 different grid sizes and everything completely for free and presented to you in a fantastic, approachable and handy format.

LogiBrain Hitori is based on the traditional Japanese number puzzle game where you use your logical reasoning to figure out which numbers to gray out.

The objective is to eliminate numbers by making some squares gray until no row or column has more than one occurrence of a given number (Hitori is Japanese for “Alone”). Additionally, gray cells cannot be adjacent, although they can be diagonal to one another. The remaining numbered cells must be connected to each other.

LogiBrain Hitori includes puzzles in different sizes (5×5, 6×6, 7×7, 8×8, 9×9, 10×10 and 12×12) and different levels of difficulty (very easy ‘1 star’, easy ‘2 stars’, medium ‘3 stars’, hard ‘4 stars’ and very hard ‘5 stars’)

If you love classic puzzle games like Sudoku, Heyawake, Kuromasu, or Binary, then you should definitely try LogiBrain Hitori. Challenge your brain and get ready to spend hours trying to solve all puzzles.

1. No duplicate numbers in rows and columns.
2. Eliminate numbers by marking them in gray.
3. Gray cells may not be horizontally and vertically adjacent. (diagonally is allowed)
4. White cells must form a single component and not be isolated.

Each puzzle has exactly one solution, which can be deduced by logical reasoning. No guessing required.

The first tap on the field will add a circle to mark the cell as correct (a circle will appear around the number), a second tap makes the cell gray, a third tap will make the cell white again.

Simple rules, eh? So warm up your brain and get ready for hours of puzzle fun!

LogiBrain Hitori user reviews :

Super fun. Simple design which I like. Very few ads (I’ve only seen one and I’ve been playing a few days).

Excellent App. # of apps acceptable. I went quickly to highest difficulty.

Enjoying the game; I’m on my second pass through all the levels. Prior to an update, when I finished a puzzle, it would automatically put me to where the next puzzle could be selected. Now I have to scroll down, and down, and down, and… just to select my next one. Gets rather tedious at times. Liked it better before. Also wish there were new updates puzzles released occasionally.

  • We have released an update today which resolves the issue with the index not automatically scrolling to the next item

This is my second review. As with the first there is a pop up that hijacks my tablet. It is a “youtube, Wal-Mart, you have won, survey type.” I use the back key until it responds. it only comes with this game. I have uninstalled and reinstalled twice. having said that, love the game.

The game is great the only problem is once in a while ads will just force open on their own NONSTOP. I have to completely quit the game and go back into it for it to stop. It’s extremely annoying.

  • Thank you for your review! We are investigating with our advertisement partner why this is happening

I have enjoyed this a lot and more than sudoku I now like to solve this before sitting to study but what I dislike about this is that it doesn’t suggest new ways to solve the game and e en if I make my own tricks most if the time it works and often it doesn’t which sometimes makes me crazy for no reason

Fun game but frustrating when only one correct solution is accepted even when there is no barrier to a slightly different solution.
