True colour — or the one that is missing. Grab it first!
A card flips up with two coloured objects. Grab the piece shown in its true colour — or, if none is, the one that is not on the card at all, neither by picture nor by colour. Beat Ada to it; a wrong grab sits you out for that card, and every deal brings trickier cards and a quicker bot. Free, no sign-up — play right in your browser.
