THE PRIME NUMBER MAZE - Paulsen
http://www.csm.astate.edu/~wpaulsen/primemaze/pmaze.html
Navigate mazes of binary numbers determined by the
distribution of the prime numbers.
Try mazes at levels for Beginners (binary notations and
prime numbers), Intermediate (500 rooms), Advanced (5000
rooms), Super Advanced (6 times larger than Advanced), or
Ultimate (the largest prime maze allowed in javascript -
can it be done?). Change one binary digit at a time to form
a new prime number, searching for a Mersenne prime.
Also explore related problems, both solved and unsolved,
and more games by Dr. Paulsen.
