Error Spotter - Find Grammar Mistakes in Real Sentences
Error Spotter trains you to notice grammar mistakes inside normal English sentences. This is different from memorizing rules in isolation because you have to read the full sentence, understand the meaning, and identify the word or phrase that breaks the grammar.
The game is especially useful for learners who can understand English but still make small errors while speaking or writing. By spotting mistakes repeatedly, you build the habit of checking tense, subject-verb agreement, prepositions, articles, and sentence structure before you answer.

What You'll Learn

Who Is This For?
This game is ideal for intermediate learners, exam candidates, job seekers, and anyone who writes emails or messages in English. It also helps advanced beginners who know grammar rules but struggle to apply them quickly.
If you often ask whether a sentence sounds right, Error Spotter gives you repeated practice with the exact skill you need: finding the one part that makes the sentence incorrect.
Tips to Score Higher
- Check the verb first because tense and subject-verb agreement errors are very common.
- Look for time words such as since, for, yesterday, already, and will; they often reveal the correct tense.
- Read the corrected sentence aloud so your ear starts recognizing natural English patterns.
- Keep a short list of the error types you miss and revise those rules after each round.
What Does the Error Spotter Game Test?
Error Spotter challenges you to find grammatical errors hidden inside otherwise normal English sentences. Each question presents a complete sentence with one deliberate mistake, and your job is to identify the word or phrase that breaks the grammar. The errors cover subject-verb agreement, tense consistency, article usage, preposition choice, and word order, which are the same mistake categories that appear in competitive exams and professional writing.
This game builds proofreading skills that are essential for anyone who writes emails, reports, academic essays, or messages in English. Spotting errors in other people's sentences trains your brain to catch the same mistakes in your own writing and speech. Over time, you develop an internal editor that works automatically, helping you sound more polished without slowing down.
Error Spotter is especially popular among competitive exam aspirants preparing for SSC, Bank PO, CAT, and government exams where sentence correction questions carry significant marks. It is also highly relevant for IELTS and TOEFL writing sections where grammar accuracy directly affects your band score.
How to Get Better at Spotting Errors
Finding grammar mistakes quickly is a trainable skill. These strategies will help you improve your accuracy and speed.
- Read the entire sentence once for meaning before looking for the error. Many mistakes only become visible when you understand what the sentence is trying to say.
- Check subject-verb agreement first. Errors where a singular subject is paired with a plural verb (or vice versa) are the most common traps, especially when other words are inserted between the subject and verb.
- Watch for tense consistency. If a sentence starts in past tense, every verb should stay in past tense unless there is a clear reason to switch. Time markers like "yesterday," "since," and "next week" are strong clues to the correct tense.
Why Proofreading Skills Matter
Small grammar errors in emails, cover letters, and exam answers create a negative impression even when the ideas are strong. Regular practice with Error Spotter builds the habit of checking your sentences before you send or submit them. Play a few rounds daily and you will notice fewer mistakes in your own writing within weeks.
