If you have already downloaded issue 12 of Sudoku Xtra you might like to re-download it in order to obtain the following corrections: a fixed Hitori puzzle on page 7 (the bottom-left puzzle had two solutions due to an unfortunate production error - please see this thread for details) clarified Chess Sum Sudoku instructions on page 43 a different Killer Sudoku variant on page 16 (some readers felt the +1 variant was disappointingly trivial so I have replaced it with a new variant) the first small Labyrinth puzzle on page 50 had the clue 1 for the last column; this should have been 2 1 clarified Tiger in the Woods instructions an updated final Haijo puzzle I apologise for these issues and hope they did not cause too much frustration.
