Friday Puzzles #72

This week I am publishing puzzles as a sort of bridge burning ceremony. These were initially scheduled to be part of the forthcoming UKPA Sudoku Championship but have had to be left out for editorial reasons. This is obviously as painful as choosing which of your favourite offspring to save from the meat grinder, but now they are out there’s no going back.

Perhaps the best way of thinking about things is this: if these were the puzzles that got the chop, how good are the ones that survived going to be?

Enjoy!

#088 Consecutive Sudoku – rated easy/10 points

(Digits in adjacent cells may be consecutive if and only if a bar between the cells is present)

#089 Deficit Sudoku – rated easy/10 points

(Place the digits 1-9 exactly once in every row and column, and at most once in the 10 marked 8-cell regions.)

P.S. Earlier versions of the consecutive had a bar missing, this one does not!
