One game at a time

Pick one and stay on it, or start a journey to rotate through everything this car can play.

• Countdown Engine

  Nine letters, longest word. Six numbers, hit the target.

  The bar: The best word in the rack and the best way to the target, both found first.

• Voice Mastermind

  Crack a hidden code of digits from the exacts and nears it reports back.

  The bar: The most guesses its own solver would ever need on a code that shape.

• Order of Magnitude

  How heavy is the Eiffel Tower? Estimates, scored on how many times off you are.

  The bar: How many times off you may be on average. Tightens every level.

• Optimal Twenty Questions

  Yes or no questions to an oracle that grades how much each one narrowed it down.

  The bar: The questions its own best-split strategy would need on the things in play.

• Chronology

  Drop events into a timeline that keeps getting more crowded.

  The bar: A streak long enough that luck cannot account for it.

• Nim Arcade

  Nim, Kayles and a subtraction game, played out loud against an opponent that never slips.

  The bar: Perfect play. Every board starts won, so clear them all without a losing move.

• Logic Grid

  Small constraint puzzles read aloud and solved in your head.

  The bar: One reading per clue. Every clue matters, so there are no spare ones.

• The Contradiction

  An account of a day out with exactly one line in it that cannot be true.

  The bar: One reading aloud, plus a re-read of the stretch holding the fault.

• Bid and Deliver

  Say how many you can name before you start naming them.

  The bar: A bid worth making, from the list's length and how hard it is.

• Border Chain

  Chain place names by last letter. The obscure ones are worth more.

  The bar: A score set by how obscure the places are, read off real populations.

• Same Page

  Say the same thing at the same moment. Matching on the obvious is worth almost nothing.

  The bar: A total no run of obvious matches can reach, read off real populations.

• Auction

  Bid each other up on how many of a category you can name, then deliver it.

  The bar: The bid worth making, from the list's own length and difficulty.

• Challenge

  Place an event on the timeline, and watch the other one try to take it off you.

  The bar: A streak long enough that luck cannot account for it.

• Race

  Question the same secret in turn. First to name it takes the round.

  The bar: The questions our own best-split strategy needs, spent between the two of you.

• Last Standing

  Take turns naming things from a category. Stall or repeat and you are out.

  The bar: How deep the table should get on this list, from its length and difficulty.

• Split Decision

  Both estimate the same quantity. The closer answer takes it, and the table still has a number to hit.

  The bar: The log-error threshold, tightened for having more than one go at it.
