LinkedIn CrossClimb #664 Solution Guide

CrossClimb puzzles challenge you to build a word ladder where each step changes exactly one letter from the previous word. Here's how to solve today's puzzle using the five clues provided.

Phase 1: Finding the Five Words

Start by solving each clue individually:

• Hint 1: Square ___ (for 529, it is 23)
  Answer: ROOT
  A square root is the number that, when multiplied by itself, gives the original number. The square root of 529 is 23.
• Hint 2: Italy's shape, more or less
  Answer: BOOT
  Italy's distinctive geographical shape resembles a boot, a common way to describe the country.
• Hint 3: Negative sounds (not cheers) heard at a sporting event
  Answer: BOOS
  When audiences disapprove, they boo. Multiple boos are spelled BOOS.
• Hint 4: Young male children
  Answer: BOYS
  Young male children are commonly called boys.
• Hint 5: What young children might get as gifts to play with
  Answer: TOYS
  Toys are playthings given to children as gifts.

Phase 2: Building the Word Ladder

Arrange these five words so each one differs by exactly one letter:

1. ROOT (starting word)
2. BOOT (change R to B)
3. BOOS (change T to S)
4. BOYS (change S to Y)
5. TOYS (change B to T)

Each transition changes only one letter, creating a valid word ladder.

Phase 3: The Compound Question

Clue: A compound word describing the uppermost parts of many buildings.

The answer is ROOFTOPS, which combines:

• Top word: ROOF (change T to F from TOYS)
• Bottom word: TOPS (change F to P from ROOF)

ROOFTOPS is a compound word meaning the upper surfaces of buildings—the roofs and tops that are visible from above. This elegant final step ties together the entire puzzle by returning to a roof-related concept, connecting back to the mathematical ROOT where the puzzle began.
