ABC Skyscrapers Sudoku (Daily Sudoku League #150)

Welcome to a puzzle that marks a significant milestone for this website, Fun With Puzzles—my 150th contribution to the Daily Sudoku League! This ABC Skyscrapers Sudoku is a creative hybrid that I've kept aside for this special occasion. The puzzle combines elements of Sudoku, Skyscrapers, and letter placement, creating a rich and multi-layered challenge. The grid contains a mix of letters (A, B, C, D, E) and digits (1, 2, 3, 4), with the core idea being that each row, column, and 3x3 box must contain different symbols. The numbers inside the grid represent building heights, and the clues outside the grid indicate how many buildings are visible from that direction, with taller buildings blocking the view of shorter ones. Letters outside the grid indicate the first letter seen from that direction.

This puzzle is a great way to celebrate a milestone while offering a unique and challenging solve. The combination of letter placement, digit logic, and Skyscraper visibility clues makes it a fascinating and rewarding experience. It's perfect for a focused session where you can explore the intricate interplay between these different rule sets. Enjoy this special milestone puzzle!

Rules of the ABC Skyscrapers Sudoku

Fill in the grid with letters A, B, C, D, E, and digits 1, 2, 3, and 4 so that each row, column, and outlined 3x3 region contains different symbols. Each number inside the grid represents the height of a building. The number clues outside of the grid indicate how many buildings can be seen when looking from that direction. Taller buildings block the view of smaller buildings, but letters do not affect visibility. Letters outside the grid indicate the first letters seen from the corresponding direction.
