Spot the Change
Two versions of the same document side by side. Click the lines you think moved, with fewer guesses than there are lines. It is scored by how much each change mattered rather than how many you found — because the heaviest change in every case is a single word. May becomes must. And becomes or. Within becomes after. It reads as identical and it inverts what the document requires, while the line everyone finds first is the one that got rewritten and means exactly the same thing. Five looks ship with it — the activity’s own, plus an archive, a museum, a control room and a winter market, drawn in the file itself with no images to load.
- Problem
- Documents get reviewed, signed off, and turn out to say something nobody agreed to. The eye reacts to length, not to meaning, so a rewritten paragraph gets read carefully and a one-word inversion goes straight past. This is the failure behind most “we reviewed it” conversations.
- Who it helps
- Anyone who signs off written work — policy, process, contracts, job aids — and quality, compliance and change teams teaching review as a skill rather than a formality.
- In training
- Have someone read the right-hand column aloud before anyone clicks. Hearing a line catches what looking past it does not, and a room that discovers this for itself will keep doing it. When they miss the heavy one, read both versions of that line back to back — it is audible and it is not visible, and the gap between those two facts is the entire session.

How to edit
- Click Edit this activity in the corner.
- Each line has an A (last version) and a B (this version). If they differ, give it a weight and a note.
- The rule that makes this work: the highest weight must be a change of one word that inverts the meaning.
- Give the low-weight changes some length. A rewritten sentence that means the same thing is what the eye goes to, and it should cost a guess.
- Do not mark a line changed unless its two versions really differ — the tool works that out from the text, so the data cannot drift.
- Click Save my version for a copy with your documents built in.
