How to play
- You are shown an English sentence with a blank (with its meaning in your language, if you chose one) — decide whether it needs mustn't or don't have to.
- Tap the option you think fits; the blank fills in and the sentence is read aloud in a British voice.
- A short rule explains why that answer is correct, so the difference sticks.
- Work through the round and aim for a flawless score, then play again to lock it in.
