# A prime maze

Mazes are very old and very diverse. I hope to write about mazes in eneral another time, but here is one variation.

Go from 1 the upper left corner to the bottom right corner with the following rules:
1) When you move from one square to the next, add the number in between
2) Every new number must be a prime number

For those of you, a prime number is a number of 2 or more which can only be divided by 1 and by itself. Thus 2, 3, 5 and so on are prime numbers, but 4, 6 and 9 are not.

I found this type of puzzle in one of the old Dutch math olympiads.

Please try to solve the puzzles on your own: your self confidence will grow. You are welcome to remark on the puzzles, and I love it when you comment variations, state wether they are too easy or too difficult, or simply your solution times. Please do not state the soultions – it spoils the fun for others. I usually make the solution available after one or two weeks through a link, which allows readers to check the solution without the temptation to scroll down a few lines before having a go at it themselves.
