As always the case after making puzzles for a contest, I had a few unused puzzles and I would like to share them here in the portal. At the same time, I can make some extra advertisement for the contest. Participation is free, only a registration at LMI is necessary. You can solve the puzzles whenever you like in the weekend. After downloading the .pdf-file you have 100 minutes to submit your solutions. You can find the instruction booklet here.
Quad Sums Sudoku (Scattered)

three digits at that corner.
Solution code: Row 5, followed by column 5.

Truly a masterpiece. Never thought that 7x7 sudokus could be so beautiful, but this series of puzzles proved me wrong very much.
