Logic number puzzle: Futoshiki.

Description: Futoshiki (also called Hutoshiki, and sometimes Unequal) is a puzzle game with numbers to be placed onto a grid. The rules of the game are as follows:
1. In each field of the NxN grid, write numbers from 1 to N.
2. In each row and each column, each number must be written exactly once.
3. All comparison relationships must be fulfilled. "A > B" meaning that the number in field A must be greater than the number in field B.
The game is a typical logic game: In order to find the correct solution of the puzzle, you have to explore the numbers already written, and by logical
thinking (concluding from what you know, that a given field must be a given number, or on the contrary, can't be a given number), determine, which fields
have to contain which numbers.
The game is played with the mouse: Click the field, where you want to write a number, then click one of the number buttons to write the corresponding number
or Clear to remove the number from the actually selected field.
