list animals until failure
Name animals against a clock that gains time with every one, under the day's rule.
Every day: A daily challenge, the same for everyone, that limits which animals count; name as many eligible animals as you can before the clock runs out. New puzzle: Once a day; the site does not state the time.

list animals until failure is a timed recall game: type animals, each one adding time to a running clock, until you run dry and the timer hits zero. Every animal needs a Wikipedia article, and overlapping names do not count twice. The daily challenge adds a rule about which animals are eligible, the same for everyone that day.
About list animals until failure
list animals until failure, by Vivian Rose, is as simple as its name. You type the names of animals, and each valid one adds a few seconds to a clock that is always running down. When it reaches zero, the game is over and your score is the number of animals you listed. Any animal with a Wikipedia article counts, checked against Wikipedia and Wikidata with a lot of hand-tuning, and the maker notes that no language models are involved.
Names must not overlap: list bear and then polar bear, and the second earns no point or extra time, though a second distinct kind of bear still counts. Order does not matter, so you can work through birds, then fish, then insects, as your memory allows. Settings let you change the starting time and the time added per animal, switch off the moving backgrounds, or show your mistakes.
The daily challenge narrows the field: on the day's puzzle, not every animal is eligible, and you have to work out what fits. Replaying a daily challenge is a supporter feature. At the end you can copy an emoji summary or your full list. It suits anyone who likes list quizzes in the style of Sporcle, with a single daily twist to share.

Tips
