sudoku round 5 ib

perhaps the possible times for clock sudoku could be more accurately put.. "all times will fall between 12:34 and 23:59" and/or "hours can be 12-24 and minutes 12-59" just sayin...

Hi mikeylyk,

Writing instructions can be a tricky business, and having written quite a few now I'm sure some aren't completely perfect. My thought process for the instructions to this puzzle was influenced by the inclusion of 0-8 Skyscrapers Sudoku - you could easily do clock sudoku with numbers from 0-8 instead, so the wider than necessary round potentially offers a little more flexibility. Whether that's the right thing to do or not can only really be judged if the instructions are clear and unambiguous to all solvers.
