How to Play Grammar Guru

Each question gives a grammar prompt with four text options — pick the correct sentence, the right word for a blank, or the version with proper punctuation. Tap your choice. A right answer scores 10 points plus a streak bonus of 5 times your current streak; a wrong answer resets the streak and highlights the correct option. Questions are drawn in random order from a pool of 24, and each game lasts exactly 20 questions.

Controls

Click or tap one of the four answer buttons to choose the correct option.
