• ✓Every thing carries a situation with it — see a thermometer on the table and you already know half of what is going on in that house
• ✓That is inference — reading a situation off an object — one of the earliest useful pieces of thinking a child does, long before anyone gives it a name
• ✓A moment must never contain the object's name, or the game is solved by spotting a matching word instead of by thinking — the verifier refuses any pair that answers itself
• ✓A landed pair gives the reason those two belong together rather than the word correct — correct teaches a child they guessed well, a reason teaches them something usable tomorrow
• ✓A wrong pair costs nothing: the two simply do not stick, and the game asks what that moment is actually short of
• ✓Not one new picture: every object is an existing Kidsquare painting already cut out on transparency — the 153 vocabulary cut-outs and the occupation props
• ✓The first draft described the pictures in my head rather than the ones on disk — it asked about rain and showed a BEACH PARASOL, called a roll of gauze a plaster, and gave a beach ball a moment about picking two teams
• ✓So all sixteen were checked against the actual paintings on a contact sheet first — a step you get to skip exactly once
• ✓Play-tested at 390px: no broken images, a miss never scolds, the set completes, and a landed pair really does give its reason

✓ = done · ☐ = planned. Every game is built one step at a time like this.
