• ✓The two modes ask one question from opposite ends: a pair is a sweep for a twin, the odd one is holding “they are all that one” and catching the exception
• ✓No card is labelled: this is a LOOKING game, and a label turns it into reading
• ✓Every glass carries its name in its aria-label, so a screen reader plays the same game the eyes do
• ✓The glasses differ by shape, garnish and colour together — never by colour alone
• ✓Four, six or nine glasses, and the ask is spoken every round
• ✓A wrong tap wobbles and puts the glasses back — three of them and the game stops for a breath
• ✓A memory mode: turn the glasses face down and open two at a timeplanned
• ✓A sorting mode: drag each glass onto the hot/cold or sweet/sour trayplanned

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