"Hi there thanks for the Suko puzzles.

Would you please generate more random patterns as the same configuration appears repeatedly and I am used to greater variety in our local newspaper - which has - unfortunately stopped featuring them.

Cheers."

"Thanks for your comment Ilus. The nine numbers in the grid are positioned completely randomly by the software so there are 362,880 different possible configurations which may appear. It is extremely unlikely that you will get the same puzzle twice. Have you tried some of the other Transum puzzles yet? There are some great ones on the Puzzle Page."
