Getting started
You can explore the demo first. To use wallet assets, open a version connected to the game server, connect your wallet and sign in.
Check the mode first
| Top-bar label | What it means |
|---|---|
| Demo | A sample collection in your browser. Actions do not buy NFTs or earn wallet rewards. Reloading resets demo progress. |
| Testnet | The website is configured for Base Sepolia. Wallet actions use test assets and need an available game server. |
| Base | The website is configured for Base mainnet. Purchases use real assets and need the correct contracts and game server. |
Demo balances belong to the sample account. Connecting your own wallet does not move those cards or rewards into it.
Connect and sign in
- 1Connect walletUse the button in the top bar
- 2Sign inApprove the sign-in message; no gas fee
- 3Use Base SepoliaThe app may ask you to switch networks
- 4Check your balancesETH pays network fees; USDC or ZOO pays purchases
Choose a supported wallet from the connection window. A sign-in message proves that you control the address. It does not buy anything or give permission to spend tokens. If you reject it, use Sign in beside the wallet button to try again.
Use test ETH and test USDC on Base Sepolia. The app may direct you to Circle’s faucet for test USDC; choose Base Sepolia there. Automatic top-ups exist only in test setups using the game’s mock USDC token. Make sure the token matches the one used by the app.
Choose your first box
Open Boxes. Pocket costs 3 USDC for one Junk or Normal card. Zoo costs 10 USDC for one card from the wider drop table. Keeper's Crate costs 45 USDC for three cards, with the first at least Rare. These are default prices; check the purchase panel.
For the welcome offer, choose one Zoo box paid in USDC before placing any other box order. If your account is eligible, the app requests a welcome voucher automatically. The offer guarantees at least Rare at the normal price. Pocket purchases, Crates and ZOO payments do not use this welcome voucher.
| Rarity | Standard Zoo draw | Welcome draw |
|---|---|---|
| Junk | 45% | – |
| Normal | 30% | – |
| Rare | 17% | 68% |
| Epic | 7% | 28% |
| Legendary | 1% | 4% |
The table shows the regular rarity roll before any separate Mythic chance or Epic+ guarantee. The welcome voucher needs the server. A refunded box order still prevents a new welcome voucher in the current game.
Understand the wallet prompts
| Prompt | What you approve |
|---|---|
| Sign in | A message to start a game session; no transaction or gas fee. |
| Approve USDC or ZOO | Permission for a particular contract to spend a token amount. The purchase is a separate step. |
| Approve cards or items | Permission for that contract to handle this collection, including future cards or items, until revoked. |
| Buy / open / forge / claim | The action itself. Network gas is paid in ETH. |
After a purchase confirms, the draw may still be waiting. Closing the animation does not cancel the order. Check Your on-chain orders on Boxes before starting another purchase.
Your next steps
- Open Cards to inspect your collection. New box and chest cards can mine immediately; transferred or market cards wait 24 hours.
- Use Teams to save four-card mining teams for +50 HP per eligible animal team. Creating a team keeps all four cards. See Cards and teams for a worked example and the Mythic bonus.
- Use Feed on Cards to level up an Epic or better. Combine uses up three cards of the same rarity to make a universal card of that rarity. Read Upgrading and merging before spending materials.
- At 8+ mining HP, daily free tickets become available. PvP needs three unlisted cards; bosses need one. Low mining HP does not stop an unlisted card from fighting with an appropriate purchased ticket.
- Visit Mining for estimates and ready rewards. Rewards need the day to close and publication to finish before you can claim.
- The game uses UTC. Tickets reset at 00:00 UTC; the top-bar countdown shows the next reset.
This guide describes the current code and its defaults. Some app previews also use defaults; deployed settings can differ. Review the network, amount and action before confirming.
