Wrodeo

Wrodeo builds its daily puzzle from books. The day's passage appears as rows of word boxes with most letters missing, such as Som___m_s for sometimes, and you complete it by guessing words in any order. When you type a word that appears in the passage, it fills in everywhere it occurs; punctuation and capital letters do not matter, and wrong guesses cost nothing except your accuracy figure. The book and its author are named above the passage, which helps with the tone and the vocabulary.

Each puzzle comes with a limited number of hints: tap a word to reveal one of its missing letters, shown in orange. A difficulty setting from Easy through Normal and Hard to Impossible changes how many letters and hints you start with, and everyone on the same level gets the same letters missing. If you are stuck you can surrender and see the passage. When you finish, the game shows your words found, correct-guess ratio and longest streak, and links to the book for anyone who wants to read on.

Wrodeo was made by a husband-and-wife team in San Francisco: Kelsey, an editor who had the idea, and Dan, who coded it. They pick the passages themselves, leaving out names, rude words and invented words, and a new one goes up every day at midnight Pacific time. The archive lists every past passage by date; playing them is part of a Patreon membership, which also brings a member dashboard with stats.

The game shows no ads; it is kept up by Patreon members, donations and book affiliate links. It suits readers who like the feel of a cryptogram but would rather fill in real words than crack a cipher.
