Here’s another WPC practice puzzle, a Magic Summer from the round of puzzles with different areas, just like the recent Different Tapa.
While on the topic of WPC puzzles: There’s a WPC series starting today on croco-puzzle. It’s authored by Silke and me, with a selection of puzzle types from Sofia. These are all “Ü2”, so you can solve them with no Java applet worries.
Rules Place digits in some cells, so that each row and column contains exactly digits 1 through 5.
Connected blocks of digits in a row or column form numbers by reading left to right or downwards, respectively. Clues outside the grid are equal to the sum of all such numbers within the corresponding row or column.
In addition, the gray cells must all have different content.
