Instructions

• Place numbers from 1 to N in the grid, and shade the remaining cells. N is indicated next to the grid.
• Within each row and column, each number can occur at most once.
• The black cells consist of pentominos:
  • A pentomino consists of 5 horizontally and vertically connected cells.
  • Pentominos must not touch horizontally and vertically. They may touch diagonally.
  • The same pentominos may occur multiple times.
• Each of the letters outside the grid is either a coded sum clue, or a pentomino clue.
• Each sum clue corresponds to an integer.
  • Sum clues are positive and may be arbitrarily large (they can have multiple digits).
  • The same sum clues correspond to the same numbers. Example
  • Different sum clues correspond to different numbers.
  • Any sum clue gives the sum of a group of connected numbers in the corresponding row or column.
• Pentomino clues give the shape of a corresponding pentomino of shaded cells. The pentomino may be reflected and rotated. The association of letters to pentomino sha- pes is given under the puzzle.
• For each group of one or more connected numbers, there is exactly one sum clue in the corresponding row or column.
• For each pentomino there is exactly one row clue and one pentomino clue, in one of the rows and columns that the pentomino is in, respectively.
• The order of the sum and pentomino clues corresponds exactly to the order of the associated cells. (In case of the U-pentomino, both position are possible.)
