Diagram Drop

Take a scrambled sentence apart and slot each word into the grammatical job it actually does.

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
