# GRAVE: Miner & Mining

<mark style="background-color:green;">**What is MINING?**</mark>

* MINING is earning $ZP or COIN by setting MINERS in MINING GRAVES.

<mark style="background-color:green;">**What is the MINING GRAVE, and how do I unlock it?**</mark>

* MINING GRAVES are where players set miners to mine $ZP or COIN. Unlock a GRAVE with SUNSHINE or COINS. More GRAVES = COMBO, which boosts mining earnings.

<mark style="background-color:green;">**What is MINING SPEED?**</mark>

* MINING SPEED determines how quickly miners earn resources. Increase it by upgrading miners or activating COMBO.

* COMBO is a multiplier that boosts mining efficiency when players deploy multiple Zombie Miners of the same star level:  Same-Star Zombie Miners = COMBO Bonus = More COINS or More $ZP!&#x20;
* Here's how the COMBO Bonuses work:
  * 3 Star 1 Miners = Level B COMBO Bonus
  * 4 Star 1 Miners = Level B+ COMBO Bonus
  * 2 Star 2 Miners = Level A COMBO Bonus
  * 4 Star 2 Miners = Level A+ COMBO Bonus
  * 2 Star 3 Miners = Level S COMBO Bonus
  * 4 Star 3 Miners = Level SS COMBO Bonus

<mark style="background-color:green;">**What is a ZOMBIE MINER, and how do I get one?**</mark>

* ZOMBIE MINERS are the core assets in Web3PvZ's Zombie-to-Earn ecosystem. They come in three varieties: COIN MINERS, SBT MINERS, and NFT MINERS, and are further categorized by three star levels: Star 1, Star 2, and Star 3. The variety of a ZOMBIE MINER determines the type of assets it generates, while the star level dictates the speed of asset production.&#x20;
* Here's a breakdown of each type:

  * **COIN MINERS:**
    1. These are the basic miners.
    2. Players can place them in the MINING GRAVE to generate in-game COINS.
  * **SBT MINERS (Soulbound Token Miners):**
    1. Players can convert 3 identical ZOMBIE MINERS into an SBT MINER by spending 200 SUNSHINE..
    2. During the Play-to-Airdrop game version, they generate ZGP tokens for players.
    3. Important: SBT MINERS are non-transferable and non-tradable.
    4. After the $ZP token launches, SBT MINERS will not directly produce $ZP.

  * **NFT Miners:**
    1. These are created by converting SBT MIENRS using SOUL NFTs, or they can be obtained directly from the ZOMBIE SHOP.
    2. They are the primary assets for Web3PvZ's Season I: THE ZOMBIES.
    3. They generate ZGP during the Play-to-Airdrop game version.
    4. After the $ZP token launches, they can directly mine $ZP tokens within the game.

<mark style="background-color:green;">**What is the difference between SBT MINERS and NFT MINERS?**</mark>

* NFT MINERS:
  * Transferable and tradable.
  * Core assets for $ZP mining after its launch.
* SBT MINERS:
  * Non-transferable and account-bound.
  * Transitional assets for ZGP mining before $ZP launch.
  * Cannot directly mine $ZP after launch.
