This game is meaningless and therefore boring-ing!
Up the game: Hold the Alt key, and press your number on the Numpad (the "small keyboard" at the right side of a full-scale computer keyboard) and then release the Alt key. Remember to turn Num Lock on!... And the row of numbers above "QWERTY..." won't work!...
Also, this textbox here won't work, either. Try it in a textbox of other applications where more (all) characters are supported. For example the M$Word wink wink.
