1. Summary

Big Booba Cards is a collectible card game on Solana. Players open card packs, collect 48 anime goddesses across six rarities, and put their best cards to work in the mine. The mine pays out $BBC every second, shared between everyone mining according to their hashpower.

Every pack roll, every balance and every mined token is decided on the game server. The browser only shows what the server already settled, so results cannot be changed from a player's device.

2. The goddesses

Each goddess belongs to one of six rarities. Every copy you pull rolls its own power inside its rarity's range, so two copies of the same goddess can be worth different amounts in the mine. Power is rolled as the average of two dice, so the middle of the range is common and the top of it is a real find.

3. Packs and odds

Every pack holds 5 cards. The chance for each card is fixed and published here and in the game. The last card of every pack has a guaranteed minimum rarity; any roll below that minimum is raised to it, and every other chance stays the same. Every wallet's first Sweetheart Pack is free.

Prices are in $BBC and are the full amount a pack costs right now.

4. Mining

A card's hashpower is its rarity multiplier times its power:

The mine releases a fixed 50,000 $BBC every hour. That amount is shared between every card mining at that moment, in proportion to hashpower:

Because the hourly amount is fixed, the total paid out never grows as more players join: more miners means each one gets a smaller share. Your share, your rate and your unclaimed balance tick live on the Mine page, and you can claim at any time.

5. Slots and fusing

• Mining slots. Every player starts with 3 slots and can unlock more with $BBC, up to 10. Only cards in slots mine.
• Fusing. Spare copies of the same goddess can be fed into your best copy for +5 power each, up to 20 above the top of its rarity's range. The spare copies are used up.

6. The $BBC token

What $BBC does in the game: it buys packs and unlocks mining slots, and it is what the mine pays out.

Where mined $BBC comes from: the game treasury, a wallet holding $BBC that funds the mine. $BBC spent on packs and slots stays with the treasury. The hourly emission is set by the team and can be changed as the game grows; the current figure is always the one shown on this page and on the Mine page.

7. Deposits and withdrawals

• Sign in with Phantom, Solflare or Backpack by signing a short message. It is not a transaction, it moves nothing and costs nothing. The game never asks for token approvals.
• Deposit by sending $BBC from your signed-in wallet to the treasury address and pasting the transaction signature in the Treasury tab. The server reads the transaction from the Solana chain itself and credits exactly what reached the treasury from your wallet, once.
• Withdraw any amount above the minimum of 10,000 $BBC. The game shows the amount you will receive before you confirm. Withdrawals are paid from the treasury to your signed-in wallet, usually within a day, and the transaction is recorded in your history.

8. Fairness and security

• Rolls use the server's cryptographic random number generator. Odds, power ranges and floors are the same numbers shown on this page.
• The game server holds no private keys. Deposits are verified on chain; payouts are sent separately from the treasury wallet.
• Balances only change through recorded actions (packs, claims, slots, deposits, withdrawals), and every one appears in your Treasury history.
• The public leaderboard ranks miners by hashpower and shows only a shortened wallet address.
