just1 is a Hitori Game Midlet.

It generates and solves puzzles for the logic game. You can also input and store your own puzzles.

There is a hint-feature included helping and explaining a next possible move. The game can be customized changing game settings and adjust colors.

A Hirori puzzle is a grid of squares which are filled with numbers. At the beginning all numbers are not marked. The goal of the game is to mark the numbers to fulfill the following three basic rules:

• Two black cells cannot be connected horizontal or vertical. Diagonal is allowed.
• In each row and each column of the grid no white duplicate numbers are allowed.
• All white cells needs to be connected orthogonally at the end. Diagonal is not enough.
