The clues indicate how many buildings are visible from that specific side. A tall building obscures any shorter buildings positioned behind it, so you must place heights that satisfy the visibility count for every row and column.
Based on source 1.
Each row and column must contain every height from 1 to N exactly once. This ensures that no height repeats, similar to the logic used in sudoku puzzles, which helps you narrow down the possible candidates for each plot.
Based on source 1.
A clue of 1 means the tallest building must be placed right at the edge of the grid. Because the tallest building hides everything behind it, it is the only one visible from that specific direction.
Based on source 1.
A clue of N means that all buildings in that row or column must climb in height order. Because they are arranged from shortest to tallest, every single building is visible when looking from that side.

Yes, you can flip to the top-down classic grid view at any time. While the 3D view allows you to spin the town and see the buildings, the top-down view provides a traditional interface for solving the logic puzzle.

Developer description, as provided in the original store listing.
Build a city with pure logic. Blocktown Puzzle is the classic Skyscrapers puzzle — a logic brain game for sudoku fans — set in a living 3D town.
Every cell of the grid is a plot, every number is a building's height, and the clues around the edge tell you how many buildings you can see looking in from that side — a tall one hides everything shorter behind it. Fill the grid so that no height repeats in any row or column and every clue is satisfied. There is always exactly one answer, and you never have to guess.
HOW A PUZZLE WORKS
- Each row and column uses every height from 1 to N exactly once.
- A clue of 1 means the tallest building stands right at the edge.
- A clue of N means the buildings climb in order, every one of them visible.
- Everything in between is deduction: which heights fit, which are ruled out, what is left.
SEE THE CITY
The numbers you place go up as towers in a downtown block with traffic on the streets. Spin the town and look along a row from any side — the clue is literally what you see. Prefer the classic grid? Flip to the top-down view any time.
PICK YOUR SIZE
4×4 for a two-minute break, up to 7×7 for a proper sit-down. Four difficulty levels change how many clues you are given, from a generous warm-up to long chains of reasoning.
TOOLS THAT RESPECT THE LOGIC
- Notes mode for pencilling in candidates.
- Conflicts flagged the moment you place a repeat.
- Check your grid at any point, or reveal the solution when you are done.
- Stuck? Spend a coin on a hint that fills one cell. Coins are earned in-app by watching a short ad — nothing to buy.
FOR FANS OF LOGIC PUZZLES
