Large Print reuses the Medium word list at full difficulty, set in bigger type for easier reading. Every printable PDF includes an answer key and is reviewed before publication.

Vocabulary analysis
Measured directly from this puzzle's own grid — not a generic estimate.
With an average word length of 5.0 letters, this puzzle sits at a moderate 41.7% grid coverage, balancing genuine challenge with enough empty space to keep scanning manageable.
Why we chose this word list
Every word here reflects the simple, visual experience of seeing a rainbow, not the physics behind it.
"After" is included since rainbows genuinely tend to appear once a rain shower has just passed, not during a full downpour.
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

Vocabulary analysis
Measured directly from this puzzle's own grid — not a generic estimate.
With an average word length of 7.0 letters, this puzzle sits at a moderate 46.7% grid coverage, balancing genuine challenge with enough empty space to keep scanning manageable. 1 of its words shares 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
"Refraction" and "droplet" name the real physical process, light bending inside individual raindrops, that actually creates a rainbow.
"Angle" is included since a rainbow's visibility genuinely depends on the specific angle between the sun, the raindrops and the viewer.
Why this level is Medium
- Horizontal, vertical and diagonal words
- No reversed words
- Mixed word lengths, some less common vocabulary
- Moderate overlaps between words

Vocabulary analysis
Measured directly from this puzzle's own grid — not a generic estimate.
With an average word length of 10.1 letters, this puzzle sits at a moderate 50.2% grid coverage, balancing genuine challenge with enough empty space to keep scanning manageable. 3 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
"Dispersion" is the genuine physics term for white light separating into its component wavelengths, the real process behind a rainbow's colors.
"Wavelength" names the actual physical property that determines each color in the spectrum, precise physics rather than a poetic description.
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 7.0 letters, this puzzle is densely packed at 58.3% grid coverage — less empty space means fewer easy gaps to scan past, so finding each word takes closer attention. 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
"Refraction" and "droplet" name the real physical process, light bending inside individual raindrops, that actually creates a rainbow.
"Angle" is included since a rainbow's visibility genuinely depends on the specific angle between the sun, the raindrops and the viewer.
