Questions, answered

FanBoosters is a free trading card game made from fan wikis. Each universe (One Piece, Genshin Impact, Marvel, Elden Ring, Gravity Falls and many more) is a complete card set forged from its community wiki. You open boosters, collect the cards, trade with friends and complete the sets.

What is FanBoosters? →

Yes. Boosters are opened with booster tokens that refill on their own, and coins are earned by playing. There is nothing to buy.

No. FanBoosters runs in the browser, on a computer or a phone. Sign in with Google or Discord to keep your collection.

No. FanBoosters is a fan project. It is not affiliated with Fandom or with the rights holders of the universes it covers. Card texts come from community wikis under their own licences (usually CC BY-SA), every card links to the page it was forged from, and artwork belongs to its respective owners.

Five different cards. The first three are Commons or Uncommons, the fourth is at least Uncommon, and the fifth is always Rare or better, with a chance of Epic, Legendary or Mythic. Cards are revealed in rising rarity, so the best one comes last.

Booster odds, explained →

The last card of a booster is Rare 58% of the time, Epic 27%, Legendary 12% and Mythic 3%. On average about one booster in seven ends on a Legendary or better, and about one in thirty-three on a Mythic.

Each booster costs a booster token. You hold up to 10 tokens and get one back every 30 minutes, so an empty stock is full again after five hours.

Common, Uncommon, Rare, Epic, Legendary and Mythic. Rarity follows fame in the fandom, blended with power when the wiki gives figures, and bosses top their set. Legendary and Mythic cards are full art with holographic foil. Mythics are numbered beyond the set, like secret rares (for example 52/50).

A booster that draws from every universe at once, with the same odds as a universe booster. It is the quickest way to discover new universes; a universe booster is the way to complete one set.

Each card is forged from one page of a community wiki: its name, subtitle, description and facts come from the page and its infobox. Rarity and ATK/DEF are computed from how famous and how powerful the character is within its universe.

How a wiki page becomes a card →

You keep them. A card's identity is its wiki page: when the page changes, the card is updated in place. When a page disappears, its card is retired: boosters stop dropping it, and everyone who owns it keeps it.

Yes. Every card has its own page with a share button. Send the link anywhere (Discord, WhatsApp, X, iMessage) and it unfurls into a preview of the card.

Probably. Any universe with an active community wiki can become a set. Small casts make small sets: a set is never padded with filler.

Every collector has a friend code. Share yours or enter a friend's, and once the request is accepted you can see each other's binders and trade.

Friends →

Propose cards and coins, ask for cards and coins in return. Nothing is held while the trade is pending: when your friend accepts, the server checks that both of you still own everything and swaps it all at once.

Trading and market guide →

Anyone can list a card for 1, 6, 24 or 72 hours, with a starting bid and an optional buyout price. Bids are held in escrow and refunded when outbid, each new bid must beat the last by at least 5%, and a bid in the last two minutes extends the auction by two minutes, so there is no sniping. A 5% fee is taken from each sale.

The market →

You start with 500 coins. After that, coins come from selling cards, from achievements (25 to 500 coins each), from trades and, once they launch, from duels. Coins cannot be bought.

Duels are FanBoosters' fight system, being built right now. Your five strongest cards of a universe face five cards of the same universe. To attack, you answer a question about the opposing card, against the clock: knowing your fandom is how you deal damage.

Duels: the full design →

A right answer deals your front card's full ATK, and a right answer given fast (in the first 40% of the time) is a critical hit worth one and a half times ATK. A wrong answer only scratches, and running out of time deals nothing. Each card has twice its DEF in hit points, and the opposing card hits back at half its ATK every round.

Your five strongest cards of the universe, by ATK plus DEF, strongest in front. Opponents are picked close to your team's strength, so a new collection meets fair fights. The better your binder, the tougher the duel and the stronger your team.

Each card has a small bank of multiple-choice questions written from that card's own facts and description, with the help of an AI model that may only use that data. Questions are checked before use, avoid dates and numbers, never ask what the card's name or art gives away, and are never repeated within a duel.

About sixteen seconds: enough to read, too short to look it up. The server starts and checks the clock, with a little grace for slow connections, and the answer never reaches your browser before you reply.

Coins. A win pays much more than a loss, and every right answer adds to the reward either way, so even a lost duel pays for what you knew.

With a Google or a Discord account. FanBoosters never sees your password.
