Tap the two words that swapped places
In each sentence, two words have swapped places — "The sat cat on the mat". Tap the two words that swapped and the sentence puts itself right. As many as you can in 60 seconds.
A right pair earns 3 + the level, plus 1 for every 3 in a row (up to +3). A wrong pair costs 2 + the level.
Spotting what's out of place means holding the sentence's structure in mind as you read — the grammar sense that makes reading fast and easy.
