What ChainPals does
A word chain is a ladder of words where each rung changes just one sound: cat → cot → cog → dog → dig. Your child sees the current word and the next word, then taps the ONE sound-tile that must change. Snuffle the mole tunnels forward a square for every word they build.
Why changing one sound matters
Noticing the single sound that changes between two words is called phoneme manipulation, and it is one of the strongest predictors of early reading. It joins two skills at once: hearing which sound is different, and decoding the new word. Word chains are a classic structured-literacy routine for exactly this.
Only decodable words — never guessing from pictures
Every word in every chain is checked against what our open Sound Road reading sequence has taught so far (a decodability gate), so your child only ever meets words they can actually sound out — never a word full of untaught spellings. When a child is stuck, ChainPals gives a gentle hint that never names the tile, and after two tries Snuffle shows the way (so there is never a dead-end) — but the game never lets a child simply keep guessing until it is right.
The chains your child builds
- short vowels a · o · i cat → cot → cog → dog → dig
- the vowels a · u cat → cut → hut → hug → hum
- the vowels a · e · u bat → bad → bed → bud → bug
- first and last sounds lap → lip → lit → fit → fig
- the digraph teams sh · ch ship → shop → chop → chip → chin
- welded endings ck · ng sock → sick → sing → sang → sung
- the vowel team ai rain → main → mail → nail → tail
Honest note: ChainPals is a calm, structured way to practise hearing and changing sounds — it is practice, not a promise of a reading level or a test score. There is no score, no streak, and nothing to buy. Everything runs on this device; there are no accounts, and nothing your child does leaves the device. Reading grows most when this kind of practice turns into lots of real books together.
