**Clue Sudoku** is a new way to enjoy this
very popular puzzle. For the beginner there is the guarantee that you will
never reach a dead end as you can always ask for another clue. For the more
experienced solver there is the opportunity to choose exactly where the
clues (seeds) are placed to give the best possible chance of solving the
puzzle.

Fill the 9x9 grid so that each column, each row, and each of the nine 3x3 boxes contains the digits from 1 to 9, only one time each.

Decide how many clues you will need and in which positions they should be. Your score is calculated as the number of digits you have correctly positioned minus the number of mistakes you have made and clues you have taken. Claim a Transum Trophy for completing the puzzle with a positive score.
