How to play

At a glance

Each card features a real work or object, with its image, its author and its source. You earn cards by opening boosters; your collection, the market, trades and leaderboards all start from there.

1. Create an account: your username is public, your email address never is.
2. The tutorial gives you 3 boosters: the first 2 contain at least one Epic card, the last one at least one Ultra Rare card. At the end, you receive 200 coins to get started.
3. Come back to open your boosters: your stock refills on its own.

Boosters

Your stock holds up to 10 boosters. A new one is added every 10 minutes, whether you’re signed in or not. When it’s full, it waits for you to open one.

A booster contains 5 cards.

Luck has a safety net: after 100 boosters in a row without a Legendary card, a Legendary is guaranteed.

The draw happens on the server, never in your browser.

You can earn more boosters by playing: the login bonus, missions, levels.

Rarities

Seven rarities, from the most common to the rarest. A card’s rarity never changes.

• Common
• Uncommon
• Rare
• Epic
• Ultra Rare
• Legendary
• Mythic

On top of that, a variant:

• Gold and silver: 1% of Epic and Ultra Rare cards drawn from a booster come out silver, 1.5% of Legendary and Mythic cards gold. Other rarities never do.

Your collection

The album sorts your cards by booster and shows the ones you’re missing.

Completing an album earns coins and a golden booster at each milestone: 5, 10, 25, 50 and 75% of its cards, then the whole album.

A duplicate can be recycled into shards; the rarer the card, the more you get:

With shards, you craft the card you’re missing: it costs 16 times what recycling it gives back. Mythics and event cards can’t be crafted.

3 showcases display your finest cards on your public profile, up to 9 per showcase.

The market and trades

Coins are earned by playing: the tutorial, the login bonus, missions, achievements, levels, and your sales.

You put a card up for auction, for free: the highest bidder gets it. When it sells, the game keeps 5% of the price.

A bid placed in the final moments of an auction extends it: no one wins it at the last second.

You offer a trade to another player: up to five cards for as many, all of the same rarity, no coins involved. If there’s no answer after 72 hours, it expires, and the cards you offered come back to you.

A card that’s for sale or offered in a trade is set aside: it can’t go twice.

New accounts have lower limits on the market: it’s a protection against abuse.

Playing with your cards

The daily quiz asks ten questions about your own cards. Five right answers earn you a booster, eight earn you two, once a day.

Battle pits two decks of twenty-five cards against each other. You play your cards across three lanes, win rounds by leading the most lanes, and make your opponent lose both lives. No cards are wagered: losing a game costs you nothing.

Progressing

Opening boosters, crafting cards, completing your albums, playing: everything earns experience. Each level gives coins and a booster; every ten levels, a golden booster is added; some levels also give you an extra slot in your stock. The top level is 100.

The login calendar is collected once a day, 28 days in a row: coins every day, boosters every seven days.

3 daily missions and 3 weekly ones: small goals, with rewards.

123 achievements to unlock, a few of which only reveal themselves once earned.

Leaderboards compare collections, week after week and season after season.

A guild brings together up to 30 players around three weekly goals, a golden booster each. Founding one costs 1,000 coins.

Your friends see your finds, and you see theirs; everyone chooses what they show.

Limited-time events bring their own cards and boosters.

Frequently asked questions

Where do the images come from?

From open collections: each image is in the public domain or under a free license. Each card’s page cites its author, its source and its license, and the credits page gathers them all.See the credits

Is the draw the same for everyone?

Yes. It happens on the server, with the same rates for every player, and those rates are published. Pity can only improve a booster.See the drop rates

What can I do with my duplicates?

Recycle them into shards to craft a card you’re missing, sell them on the market, or offer them in a trade.

Can I view my collection offline?

Yes: the collection pages you’ve already opened can be read again offline. Opening a booster, selling or trading requires a connection.
