Test your vocabulary by picking the correct antonym from 4 word choices. Tiered from Grade 9 to SAT prep across General, Science, Literature, and History — with a fill-in-the-blank context clue to help you crack the toughest opposites.

Choose Your Level and Category
Pick a difficulty tier (Grade 9, Grade 10–11, or SAT Prep) and a subject category. Start easy and climb toward SAT-level antonym pairs.
Read the Word in Context
The target word appears large on screen alongside a real usage sentence. Note how the word is used — this helps identify what its opposite would mean.
Pick the Opposite
Four single words appear as horizontal answer bars. Choose the one that is most opposite in meaning. Watch out — the three wrong answers are all synonyms of the tested word.
Use the Context Clue if Stuck
Tap 'Context Clue' to reveal a fill-in-the-blank sentence that features the antonym. The missing word is your answer — reason through which choice fits the sentence logically.
112 Antonym Pairs Across 3 Levels
A curated bank of 112 questions spanning Grade 9, Grade 10–11, and SAT prep — covering General, Science, Literature, and History vocabulary.
Distractors Are Synonyms
The three wrong answers are synonyms of the tested word — the trickiest possible wrong choices — so this is never just guessing.
Fill-in-the-Blank Context Clue
Each hint reveals a sentence with the antonym missing: 'The _______ soldier refused to leave the castle.' Read it, find which choice fits, and confirm your reasoning.
Full-Width Answer Bars
Four large horizontal answer bars make it fast to read all choices at once — a distinct visual style from definition or synonym pickers.
A word opposites quiz tests whether you know the antonym — the word with the opposite meaning — of a given vocabulary word. This game goes further than simple recall: the three wrong choices are synonyms of the tested word, so picking the antonym requires genuine understanding, not just pattern matching. With 112 antonym pairs across three difficulty tiers and four subject categories, it covers everything from everyday adjectives to SAT-level abstract nouns.
Sharpen Vocabulary Precision
Knowing a word means knowing its opposite. Antonym knowledge deepens comprehension and makes writing more precise and nuanced.
SAT-Proven Word Pairs
Many SAT reading passages test antonym awareness in context. The SAT tier here focuses on high-frequency pairs that actually appear on the test.
Harder Than You Think
Because the wrong answers are synonyms of the tested word, each question is a genuine reasoning challenge — not a process of elimination.
Learn Through Context
The fill-in-the-blank hint teaches you the antonym in a real sentence, reinforcing the word's meaning rather than just its definition.
This makes the game genuinely difficult and educational. If you pick a synonym thinking it could also mean the opposite, you'll pause and learn exactly why it doesn't. It forces precise vocabulary reasoning rather than vague guessing.
Tapping the hint reveals a fill-in-the-blank sentence where the missing word is the correct antonym — for example: 'The _______ soldier refused to leave the castle.' You reason through which of the four choices fits the sentence, reinforcing understanding rather than just giving away the answer. You get 3 hints per game.
Correct answers score 100 points at Grade 9, 150 at Grade 10–11, and 200 at SAT Prep. Consecutive correct answers add a 50 × (streak − 1) streak bonus per question.
You lose one life and the correct antonym is revealed briefly before moving on. Lose all 3 lives and the quiz ends with your final score.
Yes — choose Science, Literature, History, or General in the category selector to drill vocabulary from that domain. Choose All Topics for a mixed challenge spanning all four categories.
In Word Synonyms you pick the word closest in meaning; here you pick the word furthest in meaning. The hint mechanic is also different: synonyms uses 'eliminate a wrong answer' while antonyms uses a fill-in-the-blank sentence. The UI is also completely different — dark violet with full-width answer bars versus the game-show Kahoot grid.
