25 is a puzzle where you have to fill twenty-five boxes arranged in a square array with the numbers 1 to 25 (in order) following three rules.
Rule 1- You can start anywhere
Rule 2- After the first move, your following moves are constrained. If you move horizontally or vertically you need to leave two empty boxes between your current move and the next move. If you move diagonally, you have to leave one box empty.
Rule 3- You can only use each box once.
