# Hitori Interactive: Can you leave it alone?

Thursday, January 14, 2010

Hitori, an addictive number-elimination puzzle following the footsteps of Sudoku and Kakuro, is now available online at conceptispuzzles.com. The puzzle was originated in Japan by Nikoli under the name Hitori ni shite kure (literally "leave me alone") and is considered by many fans to be even more challenging and fun to play compared to Sudoku.

Hitori Interactive is the 12th online game released by Conceptis, allowing puzzles to be played online, saved on Conceptis’ servers and continued from any other computer anywhere on the Internet. The rules, shown below, are simple and straight-forward making these puzzles popular amongst logic puzzle fans who seek for the next 'beyond Sudoku' challenge.

## Focus on the tricky logic steps

Hitori Interactive is much more than an electronic version of the pencil and paper game. For example, by using the Auto Complete preference players can focus on the tricky logic steps while letting the computer take care of the trivial shading and un-shading steps in between. Thus, puzzle gamers can enjoy the logic challenges while relieving themselves from boring moves.

Hitori Interactive also offers features common to other Conceptis’ interactive games such as save, print (including resize and multi-page), zoom in/out, undo/redo and check solution. Thanks to those features and preferences, even very hard Hitori puzzles may be solved interactively without the need for a pencil or other accessories. For instructions how to use all game features see Hitori Interactive.

## Hitori rules

Hitori rules are simple and straight-forward. Each puzzle consists of a grid with numbers appearing in all squares. The object is to shade squares so that the numbers don’t appear in a row or column more than once. In addition, shaded squares must not touch each other vertically or horizontally while all un-shaded squares must create a single continuous area.
