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 same 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 two hours time to submit your solutions. You can find the instruction booklet here.
Perfect Squares
Place the digits from 1 to 9 in each row, column and 3x3-block. If two horizontally adjacent cells (read from left to right) form a two-digit perfect square, it is marked by a square dot. This constraint is not valid for vertically adjacent cells!
