Why we chose this word list

Every word here is a real, basic stage a child could actually observe growing a seed in a classroom cup.

"Sprout" and "root" reflect the earliest, most visible signs of a seed actually beginning to grow.

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

Puzzle IDSP-M-187 · v2026.3

Ideal for upper elementary students and casual puzzle fans.

Vocabulary analysis

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

With an average word length of 7.3 letters, this puzzle sits at a moderate 48.9% 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

"Germinate" is the correct, specific term for a seed beginning to grow, not a general word for "start."

"Disperse" and "scatter" reflect the genuine, varied ways seeds actually travel away from the parent plant.

Why this level is medium

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

Why we chose this word list

"Cotyledon" and "endosperm" are the real, specific parts inside a seed, providing structure and nourishment before true leaves grow.

"Rhizome" names a genuine type of underground plant stem, distinct from a typical root, precise botanical vocabulary rather than a generic word.

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
