NB: the wording of the rules is nonstandard. This is important. Please read them very carefully.

• Irregular 5x5 sudoku rules apply: The digits 1 through 5 appear once in every row, column, and outlined region.
• Halvers: There is one halver cell in each row, column, and region. All halver cells contain different digits. The value of the halver cell is 1/2 of its digit. A digit not in a halver cell has the value equal to the digit itself.
• Skyscrapers: Clues outside the grid tell how many values pointed by the arrow are larger than all the values before them.

Hints:

• If you are stuck because you believe there are no solutions:
  1. If the left clue of row 3 sees 5 skyscrapers in the grid, then the values in row 3 must increase, with the value in r3c5 being the largest (not necessarily 5). Then the opposite clue only sees 1 skyscraper in the grid. But the clue says 2 for some reason.
  2. What else can the 2 clue see?
  3. Each arrow points at 6 digits, not 5.
  4. The 2 in r3c6 will never be visible from the left. But the 5 in r3c0 can be seen from the right, if there is no value 5 in r3c1-5.
• If you placed 9 digits and believe the puzzle has multiple solutions:
  1. Read all the rules again.
  2. The halver cells are still important even after you've satisfied all the clues that care about values.
  3. Either r1c1 or r5c5 is not a 5. Consider where a halver with that digit can be.
