The nearest relative: you guess words to lay bare the opening section of a concealed Wikipedia article and win by uncovering the title, as in Redactle, but words close in meaning also appear, shaded gray by how near they come.
Redactle hides a Wikipedia article behind black bars, leaving only short common words such as 'the' and 'of' in view, and challenges you to name the page. Each word you guess appears everywhere it occurs, variations included, and uncovering the title ends the puzzle, so you never need the full text. The site is frank that it is hard, with most solves taking around 35 guesses and five to ten minutes. The pleasure is watching a wall of bars slowly turn into a subject you recognize.
Games that hide text and let you guess it back come first, starting with another blanked Wikipedia introduction and a blanked encyclopedia entry, then redacted stories, patents and gossip. After those come games that still revolve around a hidden Wikipedia page but give you different clues, such as its categories, page views, pictures or links.

Applies Redactle's idea to an entry from Britannica, blanking its important words. You can open up words or take hints whenever you need them, but the aim is naming the subject after revealing as little as possible.
Redaction on a smaller scale: a brief satirical news piece has ten words blacked out, and you fill them back in using the text around them, in roughly five minutes rather than Redactle's typical five to ten.
Reads like a Redactle for inventions: up to six excerpts from a real patent's dense legal wording are shown, with the product's name scrubbed, and you identify the everyday invention it covers.
Hides a name the way Redactle hides a title: a gossip blind item conceals a celebrity, and you have three strikes to identify them, as every wrong answer brings another clue and any free hints you take are shown when you share.
Fills in hidden words, as Redactle does, but only those in the name of a historical event, with eight guesses and a score that begins at 100 and drops each time you buy a clue or a letter.
Keeps the hidden Wikipedia article but starts from its filing categories instead of its text, adding clues each round over seven guesses, with a hint mode that tells you how long the article is.
Ten mystery Wikipedia articles a day, each known only from the category labels at the bottom of its page, so you deduce a title from fragments much as Redactle players do from scattered revealed words.
Another hidden Wikipedia page, but the clue is how many people visited it each week across a decade, drawn as a chart, plus what kind of article it is, with six guesses and clues after misses.
Several Wikipedia articles a day to guess from a few clues and an image, all against a timer, a quicker and more visual take on working out a page from partial information.
Uses Wikipedia differently: you travel from one article to a target through links on the page alone, trying to get there in as few clicks as possible, then measure your route against yesterday's quickest.
Redactle's own guide suggests words that test the category. A two-word title followed by dates in brackets is nearly always a person, so 'born' followed by a job or a nationality is a sensible start. For places, try city, country, river or mountain; for living things, species; and for culture or history, film, album or war.
No. Only the title matters, and it is outlined in the text; once all of its words are revealed, the puzzle is solved. In the site's example about K2, guessing 'sea' and 'mountain' fills in enough of the opening line, a peak 8,611 meters high and second only to one other on Earth, to name it. A hint button and a team-up option help if you stall.
Pedantle is the nearest, with guessed words revealing the opening of a concealed Wikipedia article, plus gray shading for near misses. Revealed does the same with a Britannica entry and asks you to uncover as little as you can, while The Daily Leak shrinks the idea to ten missing words in a brief satirical news piece.
