TF17: Runabout Sudoku

You’ve been sent out, alone, aboard the Runabout Sudoku to complete a scientific survey of a spatial phenomenon occurring on the periphery of the Typhon Expanse. Lacking the computer processing power of the station, your survey is going to take a number of hours to complete, so you look around the cabin for something to do. Luckily, you find an old Terran puzzle book. Upon reading the instructions, you decide to have a go at one of the puzzles to kill some time.

Criteria

• Your challenge must be completed on medium difficulty.
• Upon completion, submit a screenshot complete with time taken and difficulty level clear to see.
• Winner will be decided by time taken to complete.
• In the event of a tie, a winner will be chosen by date submitted.
