The Ringer: not playable today

The Ringer is built, but today you cannot play it, on any marque or on All marques. The app says "too few of its specs have been double-checked for a varied round".

Why it is hidden

A set is only served if the intruder is the one defensible answer. We check every other attribute of the cards, including family, lineage and body style, and throw the set away if any of them could single out a different car. A figure we do not have counts against the set.

That is strict on purpose, and on today's catalogue what survives keeps repeating the same few cars, which would nearly give itself away. So it stays hidden, and it opens by itself as more rows are checked. We have no date for that.

The rules, when it runs

Six sets of four cars, twelve seconds each. Three share something and one does not. Pick the intruder and see why. 100 for a right answer, plus the speed bonus. Line-Up, the extended mode, has 12 sets.
