Given a Latin or Greek root (e.g. port = carry, bio = life), tap every word on screen that contains and derives its meaning from that root. Tiered from Grade 9 common roots to SAT-level classical morphemes โ the fastest way to decode thousands of English words at once.
Choose a Difficulty
Grade 9 covers common English roots you likely encounter every day. Grade 10โ11 introduces academic roots used in science and literature. SAT Prep covers classical morphemes that unlock thousands of advanced vocabulary words.
Read the Root and Its Meaning
A root appears large on screen โ e.g. PORT โ along with its origin (Latin or Greek) and core meaning (carry). Study the meaning carefully before looking at the words.
Tap All Words That Share the Root
Six word tiles appear. Tap every word whose meaning is derived from the displayed root. Wrong choices are the same length and category โ you can't guess by appearance alone.
Check Your Answer
Hit 'Check' when you've made all your selections. Correct picks glow green, wrong picks glow red, and any you missed glow orange so you can learn exactly what you overlooked.
45 Roots Across 3 Difficulty Tiers
From grade-9 basics like AUD (hear) and BIO (life) through grade-10 roots like SPEC (look) and VOC (voice) up to SAT-level CIRCUM, OMNI, HYPER, and PROTO โ each root is paired with 6 carefully chosen words.
Pick-All Mechanic โ Not Multiple Choice
Each question shows 6 words and asks you to select every one that shares the root. Wrong choices are common English words that look similar but come from completely different origins โ you must know your etymology to win.
Etymology Hint: See the Root in Action
The hint doesn't just give a definition โ it breaks down an example word into its morphemes: 'TRANSPORT = trans (across) + port (carry)'. This teaches you to decode new words, not just memorize one answer.
Dark Indigo Inscription Aesthetic
The root is displayed like a carved golden inscription on dark indigo stone โ a visual style distinct from every other game in the series, designed to make etymology feel like archaeological discovery.
Knowing the Latin root PORT (carry) instantly helps you decode transport, portable, import, export, report, deportation, and dozens more. Roots multiply your vocabulary โ one root can unlock 10โ50 English words.
Decoys are common English words that start with similar letters or sounds but come from completely different Latin or Greek origins. For example, for TERR (earth), the decoys are terror, terrible, and terrify โ which come from terrere (to frighten), not terra (earth).
After you tap 'Check', wrong selections highlight red, missed correct words highlight orange, and perfect picks highlight green. You earn full points only for a perfect round (all correct, none wrong). This teaches precision, not guessing.
Absolutely. The SAT uses many high-frequency Latin and Greek roots. Understanding roots like BENE (good), CIRCUM (around), OMNI (all), and PROTO (first) helps you infer the meanings of unfamiliar words directly from the test, without prior memorization.
The hint breaks down a sample word into its morphemes with their individual meanings, e.g. 'AUTOBIOGRAPHY = auto (self) + bio (life) + graphy (writing)'. This teaches you to decode words structurally, not just recall definitions.
A perfect round (all correct words selected, no wrong ones) earns 200 pts (Grade 9), 300 pts (Grade 10โ11), or 400 pts (SAT Prep). Consecutive perfect rounds add a 100-point streak bonus for each round after the first. Any wrong selection or miss earns 0 and resets your streak.
