Bugs to fix

1) N-Puzzle Non Return value. Sev 1. Altough very consistent and proper wrapper
is given, this bug needs to be fixed, because the game won't start when this
bug appears.

TODO:

1) Declaring the Winner. Priority 1

2) Submission before 12:00 Tonight. ( This is an exclusive condition and will
hold good, even if both are not fixed). Package and submit. Packaging will take
30 mins to 1 hour.
