How to Play Grammar Snap
Grammar Snap is a fast, free online English grammar game. A sentence flashes up and you have just five seconds to decide whether it’s correct or incorrect. It trains the quick, instinctive grammar judgement that helps you read and speak more fluently.
Step by step
- A sentence appears on screen with a five-second timer.
- Decide quickly: is the grammar correct or incorrect?
- Tap the matching button before time runs out.
- Correct snap decisions score points; keep your streak going.
- Feeling confident? Switch to Guru mode, which removes the on-screen highlighting for a tougher test.
Tips to score higher
