ARGH
                               
ARGH is a collection of sliding block 
puzzles. The goal is always to get one 
block to a particular place. (To deter-
mine the winning destination, answer 
'Y' when you are asked whether you want 
instructions.)

You move the blocks simply by typing the 
letter of the block you want to move. The 
blocks move horizontally and vertically 
only; they do not rotate. If the block 
you want to move can move in more than 
one direction, you will be prompted to 
type an arrow key to clarify. 

What a challenge!!!
