Centumth

Centumth is a daily list-guessing game. Every day the site publishes one topic and keeps its Top 100 hidden. On 22 October 2026 it was the biggest songs of the 2000s on the Billboard Hot 100; on 2 October, the most famous TV catchphrases.

The scoring turns the usual list quiz upside down. A guess earns points equal to its rank, so naming the first thing everyone thinks of might score 3, while a correct answer ranked 96 scores 96. A guess that is not on the list scores nothing. With five guesses, a perfect day is 490 points.

Each list is researched and ranked by hand, with the sources named on the puzzle where the site can show them. Typos are forgiven when the match is clear, there is one free hint per puzzle, and after your five scored guesses an Arcade Mode lets you keep hunting the rest of the list without changing your shared score. Every past topic stays playable in the archive.

The game is made by Eliass Lalaoui, who says it began as a game played on paper with friends. It suits players who like Family Fortunes style surveys and lists, and who enjoy the risk of going for the less obvious answer.

The game is free and needs no account. Since late September 2026 it shows ads around the play screen and the archive: a banner above the puzzle, side ads on a wide desktop and a closable bar at the bottom, with nothing over the guess box.
