The Wikipedia card game.

Every card is a real article. There are 2.6 million of them, free to collect.

Why some cards are rare

Rarity is neither random nor hand-picked. It comes from the article’s real readership: the more it is read on Wikipedia, the higher its card. The most-viewed articles in the encyclopedia are the Legendaries.

What's next

01

Open and collect

Your booster supply refills on its own. Every article you discover joins your dex for good, and you can filter it by tier and search it by title.

02

Sell, bid, trade

The market puts your duplicates in play: auctions, wishlists, direct trades with other players. You earn wikicoins, and recycling gives back fragments to spend in the Workshop.

03

Quests, achievements, contests

Quests every day and every week, achievements to unlock as your collection grows, and a weekly contest you don't pass: you win it.

04

Friends and guild

Add friends, join a guild, and tackle its group quests together: every contributor gets a share of the reward.

Frequently asked questions

What is a Wikipedia TCG?

A TCG (trading card game) is a game where you get cards in sealed packs, called boosters, to build a collection. Wikidex applies this principle to Wikipedia: every card in the game matches a real encyclopedia article, with its title, its illustration and its summary. Collecting here means browsing knowledge.

How do I get cards?

By opening boosters. Each booster of the Foundations set contains five cards drawn from the corpus. Your supply refills on its own over time, with no purchase needed. Cards you're missing can also be obtained on the market, by auction or by direct trade with another player.

Are the cards rare?

Yes, five tiers structure the corpus: common, uncommon, rare, epic and legendary. An article’s tier is neither random nor hand-picked: it comes from its monthly readership on Wikipedia. The 0.06% most-read articles are legendary, and about 72% of articles are common. The full calculation and the booster odds are on the About page.

Why doesn’t a Wikipedia article have a card?

For one of two reasons. Either the article is newer than the latest catalogue update, which starts from a full export of French Wikipedia: it will join at the next one. Or the page isn’t a subject: disambiguation pages, lists, indexes, timelines, redirects and articles without a defining sentence don’t become cards. Sensitive subjects are not excluded: they are rated 16+ and hidden by default.

Is Wikidex free?

Yes. The account, boosters, collection, market and guilds are all accessible without paying. Boosters refill over time, and the in-game currency is earned by playing.

Do I need to install an app?

No. Wikidex is played in the browser, on phone and computer alike. On mobile, the page can be added to your home screen and then opens full screen, like an app.

Is Wikidex affiliated with Wikipedia or the Wikimedia Foundation?

No. Wikidex is an independent project, with no link to the Wikimedia Foundation. The game draws on Wikipedia content, published under the free CC BY-SA license, and every card links back to the article it comes from.
