Wikitrivia turns general knowledge into a sorting job: arrange it by date. Each card names something from the past, such as Sumer beginning or the United Arab Republic being established, with a label for what kind of thing it is, and you fit every new card into place on a timeline that keeps lengthening. The facts come from Wikidata and Wikipedia, and there is a dated daily game plus free play. You end up reasoning about eras you never studied by setting them beside ones you know, and that is the hook.
Time order ties the list together. The closest ask you to add events to a timeline one at a time, as Wikitrivia does, then come games that sort a whole set at once or put years on events, and closing the list are a few that apply the same ordering to films, cartoons, a globe or measurements.
The closest match: twenty events, spanning the Great Pyramid through Apollo 11, join one expanding timeline a card at a time, so it plays almost exactly like Wikitrivia with a fixed set of twenty.
Builds the timeline outward from one fixed anchor: eight events arrive in turn and each placement is judged on the spot, with no dates to enter, the same pure ordering Wikitrivia relies on.
Gives you a handful of illustrated events to drag into time order, oldest at the top, with six chances to submit and every check lighting up the cards already in the right slot, so it is Wikitrivia's sorting done as one batch.
Hands you a few events drawn from different centuries and parts of the world to put in order, then reveals if your sequence holds, practice for the cross-era comparisons Wikitrivia demands.
Groups five events under one theme, art history for example, and asks you to drop each at its year on a line, with points rising as you get nearer, a themed set where Wikitrivia mixes every subject.
Turns placement into a quick yes-or-no: for each event, decide whether it came before or after the year shown, with longer marathon and special modes after the day's run.
Lists eight world events and asks you to knock out seven until only the requested one remains, for instance the oldest, over levels that get harder, a different route to the same dating skill.
Applies the growing timeline to cinema: eight random films are slotted into release order on a single line, with a harder mode as well, aimed at players who know film history better than world history.
Puts The New Yorker's cartoons in date order, reading the artwork, fashions and type of joke to estimate when each first appeared, ordering by clues inside the picture rather than a written title.
Adds a place to the date: you pin a moment from history to its location on a 3D globe, then mark when it happened along a timeline, three rounds a day, for anyone who wants geography alongside chronology.
Keeps the ordering but leaves history behind: five mixed-up items, mountains ranked by height for one, must be arranged correctly in no more than four submissions, and each check shows only which rows are in place.
Every card is sourced from Wikidata and Wikipedia, which is why the subjects range from ancient cultures like Sumer to modern states such as the United Arab Republic, each tagged with the kind of thing it is. The site also links to GitHub for anyone who wants to report a card that looks wrong or leave other feedback.
Besides the dated daily game, there is a free play mode for extra timelines. The same creator also makes Timeframe, a daily art game, and Pinstinct, a daily map game. For more after the daily, Timdle adds eight events around a fixed anchor, and Movie Timeliner applies the same ordering to films.
The nearest is the first pick on this list, What Was When?, where you build a single timeline by adding twenty events in turn. Timdle starts from an anchor and judges each of eight placements immediately, and Chronle has you sort a handful of illustrated events with six chances to get the full order right.
