Chaotic sums

(Published on 27. July 2023, 22:47 by The Book Wyrm)


Rules:
  • Construct 5 regions in the grid. Each region consists of 5 orthogonally connected cells.
  • Place the digits 1-5 once each in every row, column and region.
  • Clues outside the grid give the sum of digits between each pair of region borders in that row/column. A ? can be any digit from 0-9 (clues cannot start with 0). A * can represent any number of clues, including 0.
In example of a completed grid is shown. In the example, the top has every clue given, while the left demonstrates the ?, ?? and * clues that are used in the main puzzle.
