Vocabulary analysis

Measured directly from this puzzle's own grid — not a generic estimate.

With an average word length of 5.2 letters, this puzzle sits at a moderate 43.3% grid coverage, balancing genuine challenge with enough empty space to keep scanning manageable. 1 of its words share letters with at least one other word on the list, so a single letter in the grid can belong to more than one hidden answer — a real source of extra difficulty beyond word count alone.

Why we chose this word list

Why this level is easy

  • Only horizontal and vertical words — no diagonals
  • No reversed words
  • Short, everyday vocabulary
  • No uncommon spellings
  • Minimal overlaps between words

Why we chose this word list

"Rookery" is the correct term for a penguin breeding colony, distinct from a generic word for a group of birds.

"Huddle" reflects the real, cooperative behavior penguins use to conserve warmth as a group, not an individual survival strategy.

Why this level is medium

  • Horizontal, vertical and diagonal words
  • No reversed words
  • Mixed word lengths, some less common vocabulary

Why we chose this word list

"Countershading" is the real, specific term for the dark-back, light-belly camouflage pattern penguins share with many other animals.

"Porpoising" names the genuine, documented swimming behavior where penguins leap above the surface, not a made-up word for this puzzle.

Why this level is hard

  • All eight directions, including reversed words
  • Longer, denser word list
  • Similar-looking decoy letter sequences in the filler
  • Frequent overlaps between words
