Wikipedia gacha
Open a pack, flip ten cards, and find out which corners of Wikipedia you just collected. WikiCollector turns 7,235,024 English Wikipedia articles into cards whose rarity comes from how many people really read them.
Registration is for adults 18+; subjects may be mature.
The genre
Gacha games are named after Japanese capsule-toy machines: you pay or wait, turn the handle, and get something random. A Wikipedia gacha game does the same with the encyclopedia. Each pack holds real articles, each article is a card, and some cards are much harder to find than others.
The idea went viral with Wikigacha, also called Wikipedia Gacha, a browser game released in February 2026 by the Japanese developer Harusugi. Other takes followed, such as WikiMasters in French and WikiCollector in English. None of them is made by Wikipedia or the Wikimedia Foundation. If you came looking for Wikigacha itself, our Wikigacha comparison and alternatives page lays out the differences with sources.
How WikiCollector does it
Each pack holds ten random articles from the whole English Wikipedia catalogue, not a curated list. New accounts get ten free Gold packs, then a free pack refills every ten minutes, with up to ten waiting for you.
Six tiers, set by human page views in August 2026. A sleepy village article is Common; a subject the whole world looked up is Legendary.
Pull the same article twice and you own two copies. Trade the spare with a friend, sell it on the Market, put it up at auction, or discard it for a WikiCoin.
Rarity tiers and odds
Every eligible article has the same chance of being drawn, so the odds simply mirror the catalogue: there are far more quiet articles than famous ones. These figures come from the live catalogue, the same source as the rarity and odds page.
| Rarity | Human views in a month | Share of cards | At least one per free pack |
|---|---|---|---|
| Common | 0–249 | 75.1% | 100.0% |
| Uncommon | 250–1,249 | 16.2% | 82.9% |
| Rare | 1,250–4,999 | 5.9% | 45.6% |
| Super rare | 5,000–24,999 | 2.3% | 20.5% |
| Ultra rare | 25,000–99,999 | 0.42% | 4.1% |
| Legendary | 100,000 or more | 0.07% | 0.65% |
Free packs use Standard odds. Gold packs leave out Common and Uncommon cards, and Legendary packs guarantee at least one Legendary. A new Legendary has a 5% chance of the Special Legendary finish. Curious what Legendary looks like this month? The most viewed Wikipedia articles are all Legendary cards.
After the pull
Thematic albums are themed pages of article slots. Cards you own drop into place on their own, so every pack can move a theme forward.
Build a public collection around any idea, from bridges to one-hit wonders. Other collectors can vote for it, once per account.
Offer one to ten of your cards for one to ten of a friend’s. They see the exact cards, then accept or decline. WikiCoins never change hands in a trade.
Missing one card for an album? The fixed-price Market lists copies in WikiCoins, the in-game currency. You always pay the lowest listed price.
Auctions last from a few minutes to twelve hours, and the highest bid wins. You can list your own spares too, at a fixed price or at auction.
Fight, in public beta, puts a team of six of your cards into campaign battles and ranked matches. Collecting never requires it.
Play before you join
The higher or lower game asks which of two articles got more views last month, which is exactly what decides rarity here. No account needed. When you are ready, read how card packs work or see the bigger picture on our Wikipedia card game page.

FAQ
A game where every card is a real Wikipedia article. You open random packs (the gacha part), each article becomes a card with a rarity, and you collect, trade or battle with what you pull. Wikigacha made the idea popular in 2026; WikiCollector is an English take built around collecting and trading.
People use “wiki gacha” and “Wikipedia gacha” for the whole genre and for Wikigacha, the browser game by the Japanese developer Harusugi, also called Wikipedia Gacha. WikiCollector is a separate, independent game.
Rarity follows how many humans read the article in the last measured month (August 2026): under 250 views is Common, 100,000 or more is Legendary, with four tiers in between. Only human views count, not bots.
In a free or Standard pack, the chance of at least one Legendary is 0.65% with today’s catalogue. Gold packs skip Common and Uncommon cards, and Legendary packs guarantee one. Every figure is on the rarity and odds page.
You keep them. Every copy stays in your collection, and you can trade it with a friend, list it on the Market or at auction, or discard it for one WikiCoin.
Free to play: ten free Gold packs to start, then a free pack every ten minutes. Premium and WikiCoins are optional. WikiCollector is an independent project, not affiliated with Wikipedia or the Wikimedia Foundation. Registration is for adults 18+.
