# Game Economy

We are currently in the process of launching a new economic model for Necrodemic. Stay tuned for more updates
Play and earn is a fundamental feature available to our community of players in the Metaverse. Bulls will be the avatar of the game player for our initial games. The mechanics of players' earning potential is as described below. There are a few key factors that affect the earning potential of a player. They are as follows:

### Earning Mechanics

Weightage Coefficients (These parameters can be changed through the Governance vote):
P : Weightage Coefficient of NFT Rarity, estimated value ≈ 1.5
Q : Weightage Coefficient of Status level of player, estimated value ≈ 1.3
R : Weightage Coefficient of Number of NFTs_rewards, estimated value ≈ 0.5
S : Weightage Coefficient of Number of NFTs_lives, estimated value ≈ 20
In short, the factors which affect SHELL token earnings are:
• Number of NFTs held
• Efficiency Score
• Rarity of NFT
• Difficulty Coefficient
• Player Status Level (XP)
Each of these variables has a number of underlying inputs from the game, and derive their values from these inputs. The definition of these variables is as follows. These rewards are only for the genesis NFT collection and the earning potential will change for future drops.

#### Number of NFTs held:

Life
The number of NFTs held in the wallet will have an impact on the earning potential but also determine the number of lives a player gets to play the games and participate. Lives get replenished every 24 hrs. Life is an entry ticket to play the games.
Formula:
$f(n) =L_{day}=[S*log_{N}(n)]$
S: Weightage coefficient for Number of NFTs for Lives (30)
N: Total Number of NFTs in the wallet (10,000)
n: Total Number of NFTs in the wallet
L_day: Total Number of Lives/Passes per day
This is an approximate representation based on the formula which determines the number of lives.

The Player can replenish their NFT by burning 1000 Shell tokens for the first time. This increases exponentially every time an NFT is replenished. Also every time an NFT is replenished, They lose the auto-replenishment for that window of time.

#### Experience Points:

This involves the XP that a player has gathered on Bullieverse. A higher XP percentage offers better earning potential.

#### Efficiency Score:

This relies on how well the player performs in the specific game. How a player wins the game, or how well they survive the game. There are multiple factors that will be considered by the game developer to create an efficiency score. Some of these may include EPM, K/D, Engagement, and PMPM.
EPM: Effective Actions Per Minute
K/D: Kill Death Ratio(How many kills a player gets before they die each time they spawn)
PMPM - Plus Minus Per Minture
Efficiency score varies from 0 to 1 depending on how the player performs in the game

#### Difficulty Level:

The difficulty level of the game will also decide the earning potential. Winning a higher difficulty level will increase the rewards earned for our players. Depending on the level of the game the difficulty is constant. Within the game, each level will have a difficulty level with each level having a difficulty constant and it varies between each game too depending on the type of the game. This is determined by the average time it takes for the player to complete the game. Difficulty constants will be determined by the data collected from the players and this adjusts to the mean over a period of time.

#### Rarity:

Our Rarity algorithm will identify a score for each of the NFTs. The rarer the NFT avatar, the greater the earning potential. The rarest NFTs will receive exponentially higher earning potential.
RM = P^(1-(R/T))
R : Rarity Score (1-10000)
