How SkylineGlyph works (60 seconds)
A skyscrapers puzzle: one tower of every height in each row and column, and the edge numbers tell you what a person standing there would see.
1) The rules
The grid is a city block. Every lot gets a tower, and every row and every column holds one tower of each height from 1 up to the grid size. No repeats, just like Sudoku without the boxes.
2) The clues
A number on the edge is a viewpoint. It counts how many towers are visible looking down that line from there. A taller tower hides every shorter tower behind it. Looking at 4 1 3 2 5 from the left, the 4 hides the 1, 3 and 2, and only the 5 rises above it, so that line reads 2.
3) Winning moves
Start with the extremes. A 1 pins the tallest tower right next to it. An N forces the whole line to climb in order. A 2 means the tallest tower is not in the first spot, and the first spot is not the second tallest either.
After that it is pure elimination: every lot you fix removes a height from its row and its column. The clues turn gold when their line is right.
Daily and practice
The daily skyline is a 5×5, the same for everyone and reset at midnight UTC. Practice boards at 4×4, 5×5 and 6×6 are endless and random. Your daily streak and best times are saved on this device.
Why it is good for you
Skyscrapers puzzles train spatial reasoning and constraint tracking at the same time: you hold a mental picture of a line while eliminating options in two directions. Short, satisfying, and different every day.
