How to play
Add prefixes and suffixes onto the base word to build as many words as you can.
Finding words
The empty boxes at the top show how many words you need to find. Every time you build a new word, one dot lights up. Wider boxes are for longer words with more morphemes!
Endings like -s, -ed and -ing
These make a new form of a word you've already found — not a new word. So react, reacts, reacted and reacting all share one box. They still score points, and if you find every form of a word, its box gets a shiny ring!
Stuck? Use a hint
Tap the next to Build … words and we'll tell you the meaning of a word you haven't found yet and light up the prefix it needs — you work out the rest! You get three hints a game, and you need to find each hinted word before the next hint unlocks.
When all the boxes are lit
You've done it! You can finish there — or keep going. There are often more words hiding, and every extra one you find will push your score higher on the leaderboard!
Spelling clues
Sometimes the spelling changes where two parts join. Watch for these:
nDouble letters — a letter is added and highlighted in yellow (e.g. run + ing → running).
eOmissions — a silent letter is dropped and shown crossed out (e.g. elevate + ion → elevateion).
yiy → i — a y changes to an i, shown in yellow (e.g. carry + es → carries).
iVowel connectors — a joining letter highlighted in blue glues the parts together (e.g. art + i + st → artist).
