Duels use a quiz drawn from your own cards: your card's attack stat scores points while its defense stat absorbs hits.

Can I trade or auction cards?

Yes. You can propose duplicates in direct negotiation with other players, and you can put cards up for auction or bid before the countdown ends.

Are there social features?

Yes — you can add friends, message them, challenge them without leaving the conversation, join guilds that climb a team leaderboard, and unlock achievements in regular contests.

Is there any content warning?

Yes. At signup you must confirm you are at least 18 and understand that cards come from Wikipedia and may include sensitive content.

Is the platform open source?

The page does not say whether the platform itself is open source; only the card content, sourced from Wikipedia, is under the free CC BY-SA license.

WikiMasters — L'encyclopédie devient votre terrain de jeu

WikiMasters turns Wikipedia into a collectible card game. Every card is generated from a real Wikipedia article: the article's readership determines the card's rarity, its length determines attack, and its quality determines defense. Players open packs of randomly drawn articles, complete their collection album, duel friends with quiz-based card battles, trade duplicates, bid in auctions, join guilds, chat with friends, and climb leaderboards. The site is in French and content is Wikipedia material under the CC BY-SA free license.

Key Features

Wikipedia-powered cards

Each card comes from a real Wikipedia article: readership fixes its rarity, article length fixes its attack stat, and article quality fixes its defense stat (e.g., Saturn at 8,790 attack / 6,900 defense as a Legendary 'L' card, the bee at 2,070 / 8,260 as a Common 'C').

Pack opening

Open packs of randomly drawn articles — the more an article is read, the rarer the card that comes out of the pack.

Collection album

Organize your collection by tags (Sciences, Histoire, etc.), pin your favorite cards, and track which ones you're still missing.

Duels with friends

Battle friends with a quiz built from your own cards; the attack stat scores points while the defense stat absorbs hits.

Trading

Offer your duplicates in exchange for cards you're missing and negotiate directly with other players.

Auctions

Put a card up for auction, or hunt for a bargain before the countdown ends (e.g., a live auction at 1,240 with 7 bids and 02:14:09 remaining).

Guilds

Form a group with other players, chat together, and climb the team leaderboard (e.g., guild 'Les Encyclopédistes' with 12 members).

Friends and messaging

Add friends, message them, and challenge them to duels without leaving the conversation.

How It Works

1. Cards are generated from Wikipedia

Each card derives from a real article: readership sets rarity (tiers like C, R, SR, UR, PC, L), length sets attack, quality sets defense.

2. Open packs and build your album

Draw random articles from packs, sort your collection with tags, pin favorites, and identify missing cards.

3. Duel, trade, bid and team up

Challenge friends to quiz duels, swap duplicates in direct negotiation, bid in timed auctions, and join guilds to climb the rankings.

FAQ

What is WikiMasters?

WikiMasters is a French-language collectible card game built on Wikipedia: every card comes from a real Wikipedia article, with rarity set by the article's readership, attack by its length, and defense by its quality.

Is WikiMasters free?

Yes — creating an account is free, and the card content comes from Wikipedia under the free CC BY-SA license.

How do card stats work?

A card's rarity depends on how much its source article is read, its attack corresponds to the article's length, and its defense corresponds to the article's quality. Cards carry rarity tiers such as C, R, SR, UR, PC and L.
