Try to clear the board by jumping pegs over other pegs. Just click on the peg you wish to move. The "jumped" peg will be removed from the field. If there's more than one move available, just choose which move you would like to do. You win by getting it down to just one peg. (The best solution is with this peg in the center).
==========================
Installation is simple :
1) copy the peg.tar.gz to any folder
2) go to the folder from terminal
3) plasmapkg -i peg.tar.gz
