Centumth

A trivia game that punishes the answer you thought of first. Each day announces a topic with a hidden Top 100 behind it, and your score for any answer is simply its position on that list: name the thing at #2 and you bank two points, dig out the one sitting at #93 and you bank ninety-three. Five guesses, a ceiling of 490, and the whole exercise is talking yourself out of the obvious.

1. Read the topic and the sourcing note under it. The note says which dataset the ranking comes from and how ties were broken, which quietly decides what will and will not be accepted.
2. Type an answer. Spelling is forgiven, but vagueness is not - abbreviations and loose names usually fail to match.

The scoring inverts what trivia normally rewards. Knowing the biggest name in a category is nearly worthless here, and the run is won by whoever can reach the unglamorous middle of a list and stop themselves from naming the famous thing. That makes it a genuinely different exercise from a quiz, and it is over in a couple of minutes with no clock pushing you. It suits people who enjoy datasets and rankings and are happy to argue with a source. It suits badly anyone who wants to feel quick and clever, because your best-known answer is usually your worst one, and a five-guess run can finish on nothing at all if none of them made the hundred. The obvious weak point is that a Top 100 is only as good as whatever list it was built from - each topic prints its source and its tie-break rule under the title, and you can judge it for yourself. The archive is free to replay, so a bad day is never the end of it.

Every guess comes back with a coloured dot, a verdict and its exact rank: an orange 'Way too obvious' for the household names near the top of the list, a green 'Solid pick' through the middle, and a 'Deep cut!' target for the ones buried near #100. An answer that is not on the list scores nothing. A bar across the top tracks your running total against the four medal thresholds - 50, 150, 300 and a perfect 490 - and the game narrates as you go, in a tone somewhere between a quizmaster and a heckler.

Daily topic

The official run: one topic, five guesses, scored out of 490. This is what feeds your medals and stats.

Arcade Mode

Unlocks once your five guesses are spent, and lets you keep going after the whole hundred with no limit. Your official score stays frozen at the first five. Choosing to reveal the full list instead locks Arcade for that topic.

• The reflex answer is the trap. In the game's own example, Dog comes back at #3 and pays three points while Axolotl at #96 pays ninety-six. Ask which entries you would defend as 'yes, that technically belongs on the list' rather than which ones you are sure of.
• Take the free hint early instead of hoarding it. It costs none of your five guesses, and it is only worth anything while you still have guesses left to convert it into points.
