Prime Maze 2
Below is a maze of numbers. Start at the number in ( ) and make your way to the number in [ ], by moving only between adjacent numbers (not diagonally) whose difference is a prime number. For instance, you can move from a 4 to a 15 (or vice versa) because the difference is 11, a prime number. Remember: 2 is a prime number, but 1 and 0 are not!
