Skyscraper Rows

Fill a grid with towers so every row and column holds each height once, and the clues around the edge match the towers you can see. Daily and practice.

How to play

  1. Select a square and place a height from 1 up to the grid size. Each height appears exactly once in every row and every column.
  2. A clue on the edge tells you how many towers are visible from that side. Taller towers hide shorter ones behind them.
  3. Pre-filled squares are locked. Repeats are shown in red, and clues that cannot be met turn red once their line is full.
  4. You can also type digits on a keyboard, and Backspace to erase.

Tips and strategy

  • A clue of 1 means the tallest tower sits right at that edge.
  • A clue equal to the grid size means the heights ascend in order from that side.
  • Combine row and column repeats first, then use the clues to place the tallest tower.
  • The tallest tower is always visible, and it hides everything behind it.
