From Wordle to Clair Obscurdle: a short history of “-dle” games

Wordle, where it all began

It all starts with Wordle, a small word game made by software engineer Josh Wardle, originally for his partner. The rules fit in one sentence: find a five-letter English word in six guesses. After each guess the letters change colour: green when they are in the right place, yellow when they appear elsewhere in the word, grey when they are not in it at all.

The game was released to the public in October 2021, and by the turn of 2022 it was everywhere. What drove that spread was a seemingly minor detail: the result grid, which anyone could copy as emojis and share without giving the word away. In January 2022, The New York Times bought the game.

One grid a day, the same for everyone: a constraint that could have looked like a limitation became the genre's signature.

A wave of spin-offs

Wordle's success opened the floodgates. Throughout 2022, variants multiplied: Worldle asks you to guess a country from its outline, Heardle a song from its opening notes, and Quordle makes you solve four grids at once. The "-dle" suffix became a brand of its own: read the name and you know what to expect.

Fan communities quickly adopted the format. LoLdle, dedicated to League of Legends, is one of the best-known examples: instead of a word, you guess one of the game's champions. Spin-offs then appeared for a great many video game, TV and sports franchises.

Why the formula works

Several ingredients explain the genre's staying power, and Clair Obscurdle keeps all of them:

• One puzzle a day, the same for everyone. Everybody faces the same challenge, which turns it into a conversation topic: you compare, you tease, you help each other without giving anything away.
• Short sessions. A few minutes are enough, and scarcity keeps you coming back: once the puzzle is solved, you have to wait until tomorrow.
• Spoiler-free sharing. The emoji grid tells the story of a game without revealing the answer, and every shared grid invites whoever sees it to have a go.
• Streaks. Coming back every day so as not to break your streak is a simple hook, but a stubborn one.

None of this needs an account, a download or a tutorial: you understand the rules on your first guess. That is probably what allowed the format to win over very different audiences, from crossword lovers to video game fans.

What fandom games changed

"-dle" games built around a fictional universe pushed the formula in several directions.

The first is the attribute grid. Instead of letters, each guess compares the features of the character you suggest with those of the answer: their role, their origin, when they first appear. A green, orange or red cell replaces the well-placed or misplaced letter. The game no longer tests your vocabulary but your knowledge of a world.

Then came multiple modes. A single franchise offers plenty of variety: a line to attribute, a picture to recognise, a detail to identify. Each mode calls on a different kind of memory, and a player who shines in one can stumble in another.

Finally, many of these games dropped the guess limit. The stakes shift: it is no longer about winning or losing, but about getting there in as few tries as possible. Deduction becomes a small optimisation exercise, with favourite openings and strategies, as our analysis of the best first guess shows.

Clair Obscurdle's choices

Clair Obscurdle takes these conventions and adapts them to Clair Obscur: Expedition 33. A few decisions deserve an explanation.

Five modes, two ways to play. Classic compares six attributes (category, role, gender, affiliation, combat and zone), and Complete does the same across the whole roster, mobs included. Quote, Weapons and Mob rely on your memory of the game rather than deduction.

Data taken from the game. The names of characters, weapons and enemies, as well as the lines in Quote mode, come from the game's own files, cross-checked against community wikis. The weapon icons and enemy portraits are the ones the game itself displays.

A bilingual site. Everything exists in English and French, with each language's official names. The search accepts both spellings: you can type "Peintresse" on the English site or "Lampmaster" on the French one.

No guess limit, but a free mode. You cannot lose a daily game. To practise without waiting until tomorrow, free mode draws as many random answers as you like.

Clues everyone can read. In the grid, every exact cell carries a ✓ and every partial cell a ◐, so the clues stay clear even if you cannot tell the colours apart.

Stats that stay with you. Streaks and records are saved in your browser, with no account and no data collection. How the daily draw works is explained in a behind-the-scenes article.

No thumbnails where they would let you cheat. In Weapons and Mob, the answer depends on a picture. The search suggestions in those modes therefore deliberately show no thumbnails: otherwise you could simply match the day's picture against the miniatures in the list. Classic, which has no picture to guess, keeps the portraits in its suggestions.
