Skyscrapers: today's puzzle
Today's puzzle
Loading ยท the grid and its level
(a small spoiler)
Checked: exactly one solution, reachable by logic. The level is the hardest technique our solver needed, not the grid size.
Settings
Rule breaks (a repeated height) always show in red. "Show mistakes" also marks cells that disagree with the solution.
Every cell holds a tower from 1 to N storeys, each height once per row and column. A clue outside the grid says how many towers you see from there: a taller tower hides every shorter one behind it. Every daily puzzle has exactly one solution.
The rules in three lines
- Each row and each column contains every height from 1 to N exactly once.
- A clue tells how many towers are visible from that side, looking along the row or column; taller towers hide shorter ones.
- Lines without a clue can show any number.
Skyscrapers is also known as towers. Full rules and a worked example.

Seeing the city
Read a clue as a view down a street. A 1 means the tallest tower stands right at the start, hiding the rest. A clue equal to the grid size means every tower is visible, so they rise one step at a time. Everything in between is a story of tall towers kept back from the edge.
Small grid, deep logic
A 6x6 skyscraper puzzle has only 36 cells, but a clue of 3 can be met in dozens of ways. The harder levels ask you to list the orders a whole line can take; Expert ones add a short contradiction.
Questions
Can a tower be hidden by one of the same height?
There are no two equal towers in a line, so it never happens: each height appears once per row and column.
Why do some puzzles show a few heights already?
A full set of clues does not always pin a grid down, so some puzzles reveal a height or two; others leave clues out instead.
What does a faded clue mean?
Its line is full and the view matches. A clue turns red when the full line does not match it.
