Open packs
Every booster holds ten random cards from the whole English Wikipedia article catalogue. New accounts start with ten free packs, and a free pack refills every ten minutes.
Wikipedia card game
The Wikipedia card game made for collectors.
WikiCollector turns 7,235,024 English Wikipedia articles into collectible cards. Open packs of ten, keep every pull, and chase rarity that comes from how many people actually read each article.
Registration is for adults 18+; subjects may be mature.
How it plays
Pull, keep, show off.
Chase rarity
Rarity follows real readership in August 2026: fewer than 250 human views is Common, 100,000 or more is Legendary. All tiers and odds are published on the rarity page.
Build something
Keep duplicates, publish themed collections that others vote on, fill thematic albums and bid on cards in the marketplace.
WikiCollector and Wikigacha
Two different takes on Wikipedia cards.
Wikigacha, also called Wikipedia Gacha, is a separate game by the Japanese developer Harusugi, released in February 2026. Both games are independent and unofficial; neither is made by Wikipedia or the Wikimedia Foundation. Here is how they differ, based on public information checked on 29 September 2026.
| WikiCollector | Wikigacha | |
|---|---|---|
| Focus | Collecting: collections, albums, marketplace. No combat. | Collecting plus battles, raids and a story mode |
| What sets rarity | Human page views in the last measured month | The article’s Wikipedia quality assessment |
| Card text | Wikipedia excerpt, linked to the exact revision | Flavor text on rarer cards written by a language model |
| Free packs | Ten at signup, then one every ten minutes (up to ten) | Ten daily packs, plus mission rewards |
| Your collection | Saved to your account | Saved in the browser, with an optional beta server sync |
| Languages | English Wikipedia | Follows the game language, e.g. English or Japanese |
Sources: the Wikipedia article on Wikigacha (revision of 16 September 2026) and the public Wikigacha site as seen on 29 September 2026. Features change; check each game for the latest. If you enjoy battles, Wikigacha is built around them. If you would rather build a collection people can browse and vote on, WikiCollector is made for that. French speakers can also read our comparison with WikiMasters, a French-language Wikipedia card game.
