Take a scrambled sentence apart and slot each word into the grammatical job it actually does.
Was this fun?
How to play
A sentence is broken into word-cards and an empty diagram of labelled roles. Drag each card into the slot that matches its part in the sentence, subject, verb, object, modifier and more, until the structure is whole again.
Match every word to its grammatical function
A word only locks in when it lands on the correct role
Fill the whole frame to clear the sentence
Harder rounds add longer sentences and trickier modifiers
Controls
Desktop: drag a word-card onto a slot, or click a card then click its slot; pick difficulty with the on-screen buttons
Phone & tablet: tap a card then tap its slot, or drag with your finger
Game modes
Daily: one shared, seeded set with a global ranking
Practice: endless fresh sentences, with Easy, Medium and Hard settings
Tips & strategy
Find the verb first, then the subject doing it, the rest of the roles fall into place around them
Modifiers attach to the noun or verb they describe; place the core before the extras
Use the timer pressure to commit on obvious slots and save the ambiguous words for last
