# Item Mining/Minting Mechanics

The amount of PENTA STONE mined is determined by these parameters.

- Parameters of your Headphones
- Song you've listened to
- The total supply of PENTA STONE

**Mining or Not Probability Function (named "Gamma")**

$f(x) = 5ｍ\frac{1}{\Gamma{(5)}}(x+1)^{5-1} e^{-(x+1)}$

**x**

$x = rarity (1 - \frac{5}{5\times rarity + level})$

**m**

$m = \begin{cases} 1 \\ t \ (LuckyQuest=1, Beginner=1) \\ 0 \ (TotalSupply≥Cap, Song=AlreadyListened) \end{cases}$

****

**Cap**

Cap is a daily Mining Cap. If the maximum amount is mined on a given day, no more can be mined. This value varies depending on

- the market distribution of the Headphone
- the number of songs listened to on PENTA

$M = randbetween(1, 3)$

The amount of stickers minted is determined completely at random.

The amount of accessories minted is determined completely at random.
