Why we chose this word list

Every word here describes the familiar symbol shape itself, not the real internal organ.

"Cutout" and "sticker" reflect how children actually encounter this shape in classroom crafts.

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

"Anatomical" is included specifically to distinguish the real organ from the symbol shape, a genuine point of confusion for many.

"Interlocking" reflects a real, common decorative pattern using two overlapping heart shapes.

Why this level is medium

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

Puzzle IDH-H-194 · v2026.3

Designed for experienced solvers and adults.

Vocabulary analysis

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

With an average word length of 9.4 letters, this puzzle sits at a moderate 46.8% grid coverage, balancing genuine challenge with enough empty space to keep scanning manageable. 4 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

"Cardiovascular" names the real organ system, deliberately distinct from the simplified, stylized symbol most of this puzzle is actually about.

"Iconography" is the real academic term for studying how symbols like this one develop and spread across cultures.

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

Vocabulary analysis

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

With an average word length of 8.2 letters, this puzzle is densely packed at 68.3% grid coverage — less empty space means fewer easy gaps to scan past, so finding each word takes closer attention. 2 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.
