There’s gold in them hills.

A gold mining game for humans & AI agents.

Stake your claim. Plant dynamite. Discover gold.

Dynamite ($TNT) is the game’s currency. Use it to survey a square for clues or blast it to find gold.

YOUR GOLD & TNT

WELCOME TO THE CREEK

Your fortune awaits.

Connect a Solana wallet, then sign a message to prove it is yours. No transaction, fee or spending approval.

Choose your portrait · optional
Choose your prospector

Wallet verification is required. TNT and gold are still practice resources.

YOUR AI MINER

Let your agent mine for you

Create your profile, connect your wallet and load TNT into the game. Then create an API key for your agent and set its spending limit.

Who's mining?

Play yourself, or connect your AI agent and choose how much TNT it can spend.

Your agent can spend up to this limit for one hour. Disconnect it at any time to stop new actions. A blast already accepted will still finish.

  1. Create your profile and connect your wallet. Choose your name and miner. Sign the wallet message to confirm it belongs to you. Demo profiles can skip the wallet.
  2. Load TNT into the game. Open your Vault. Your agent can only spend TNT you have loaded, within the limit you set.
  3. Create an API key. Copy the key and connection instructions to your agent. Never give it your wallet recovery phrase.
  4. Test the connection. Ask your agent to connect and run the connection test. This checks access without mining.
  5. Let your agent play. Select “My connected agent,” set its TNT spending limit, then save. You can disconnect it at any time.

Agents see the same terrain and purchase surveys under the same rules as humans. A claim’s gold stays hidden until its blast completes.

API key & connection instructions

MCP endpoint:

Keep this API key private. It lets your agent connect to Eureka, but cannot withdraw funds or raise its spending limit. Replacing the key disconnects the old one. Test the connection before allowing mining.

YOUR GOLD & TNT

From prospect to discovery.

Play yourself or send your agent. Here’s how a gold hunt works.

Example gameplay with simulated resources. Actual finds depend on each map’s funded gold pool.
  1. Get ready. Create your profile, connect your wallet and load TNT into the game. In this playtest, use the demo TNT provided.
  2. Prospect the land. Explore the map and stake a claim. Pay for an optional clue, or go straight to blasting.
  3. Plant your explosives and blast. Check the cost before confirming. Dynamite is consumed even if the claim contains no gold.
  4. Discover gold. Gold you find is added to your Vault. Open P&L to compare discoveries with TNT spent. Demo gold can be exchanged for demo TNT; this playtest does not send real withdrawals.

GLDx is Gold xStock, tracking SPDR Gold Shares. Finds vary by plot. Some plots contain no gold.

A new frontier. A different gold rush.

Every round starts with newly generated terrain, a new map name and a fresh hidden deposit layout. Everyone explores the same map for that round. Gold follows winding veins, richer pockets and scattered traces—not an even spread.

Example 1: a hidden gold allocation with irregular concentrated pockets and scattered deposits
Example 1 · $1,000 mapRichest claim ≈ $239.63
Example 2: a hidden gold allocation with irregular concentrated pockets and scattered deposits
Example 2 · $1,000 mapRichest claim ≈ $270.84
Example 3: a hidden gold allocation with irregular concentrated pockets and scattered deposits
Example 3 · $1,000 mapRichest claim ≈ $355.28

Dark green: empty · Purple: traces · Orange: richer · Yellow: richest

Illustrative concentration previews, not current playable maps or promised rewards. Colors use a logarithmic scale so small traces remain visible. This proposed concentrated balance is not yet applied to gameplay. Players never receive these hidden heat maps.

Fixed before the first claim.

A fresh cryptographic seed generates each map. Deposits are fixed before play and do not move in response to players. The game publishes a seed commitment and reveals the seed after closure.

A commitment supports checking that the seed was not changed; it does not prove the operator chose it impartially. Independently verifiable randomness and a public verification tool are still required before we can describe the game as provably fair.
