Blocktown Puzzle: Skyscrapers

Place every building on the right floor using nothing but logic. Four sizes, four difficulties, a 3D city you can spin — and every puzzle has exactly one solution.

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 If you enjoy sudoku, KenKen, kakuro, nonograms or any brain teaser that rewards careful thinking, Skyscrapers (also known as Towers) is the next puzzle to learn. The rules take a minute; the deductions keep getting deeper.

MADE FOR SHORT SESSIONS Puzzles are generated on the device, so there is always a fresh one and the game works offline, with no connection needed. Your game is saved as you play; leave and come back whenever.
