9 of 9 - Help

9 of 9 is little game of logic: Push buttons to manipulate the numbers written on them.
You need a Javascript-capable browser to play it.

The goal is to make all numbers look the same!

At the beginning of each game you have to decide how difficult it should be to solve it, by simply pressing one of the 9 buttons (1=easy, 9=hard).

If you click on a certain button, the numbers of all buttons in the same row and column will be risen!

Explanation of the buttons at the bottom of the game:

New game - Starts a new game.
Repeat - The computer repeats the last problem.
Exit - The game ends.

Play 9 of 9!
