Word Chain Level 129 Answers
The full answer is RADIO → CARBON → FIBER → OPTIC → …, with a definition for every word. This chain is longer than the game average of 6.8 words.
Level 129 — 8 Words
Read it left to right: every neighbouring pair makes a compound or a phrase. More chains are in levels 101–150.
Why Each Word Follows the Last
Each pair below is the compound or phrase that joins two neighbours. Spotting one usually gives you the next.
What Each Word Means

How to Break Level 129 Open
Start from the ends, not the middle
The first and last words have only one neighbour each, so they carry the least ambiguity. Here that is RADIO and STAMP. The same trick works on every chain in levels 101-150.
A word can join in either direction
Chains use compounds both ways round — radio carbon reads forwards, but many links only work if you try the reverse. If a word refuses to fit, flip the pair.
Check the second meaning
8 of the words here carry a definition above. Chains lean on secondary senses far more than the obvious one, which is why a link can look wrong until you read what the word actually means.
How to Solve a Word Chain Level
Ends first, then work inwards.
Read the chain as a sequence
It is not a word list. Each answer must join the one before it, so the order is part of the puzzle — see the full level list for how they grow.
Anchor at both ends
The outer words have a single neighbour each, so they are the least ambiguous place to start.
Try the pair both ways
Compounds work in one direction only. When a candidate stalls, reverse it before discarding it.
Verified Answers, Not Guesses
How we verify every chain for all 569 levels, with definitions for the words
Levels are taken from the published answers and cross-checked against a second source, which agreed on all 520 levels it covers. The game itself ends at level 569: the source answers HTTP 200 for any higher number and serves one repeated puzzle, so those are deliberately not published. The routine is in our methodology and the standards in our editorial policy.
