Hi! This puzzle explores a variation on the classic Skyscraper rules. I really hope you will enjoy it!


Rules

  • Sudoku: Fill every row, column, and 3x3 box with the digits 1–9 once each.
  • Thermometers: Digits on a thermometer must strictly increase starting from the bulb end.
  • Renban (Magenta): Digits on a magenta line must form a set of non-repeating consecutive numbers in any order.
  • German Whispers (Green): Adjacent digits on a green line must have a difference of at least 5.
  • X/V: Digits separated by an 'X' must sum to 10. Digits separated by a 'V' must sum to 5.
  • Hidden Skyscrapers: Each digit in the grid represents the height of a building. Taller buildings obstruct the view of shorter buildings behind them.
  • Vantage Points: A digit in a cell with a square (located at the start or end of a row or column) counts how many buildings are visible from that direction, including itself.
  • Corner Clues: A clue in a corner cell applies to both its row and column unless an arrow indicates a specific direction.

Example: If R6C9 was 3, a valid row 6 could look like: 245789613 (the visible skyscrapers are: 3, 6, and 9).

Needed a bit of time to get my head around the new rule and I usually can do 2 star puzzles on this site but was able to completed it an about 30 minutes the same time as the Logic Lemur Gaming Youtube channel did.
