# Experience points (PXP)

## PXP formula

Experience Points (PXP) are calculated by multiplying Boosted Points and the Rarity level of the digital collectible Pookyball. 

$$
PXP = Boosted Points \* RarityMultiplier
$$

PXP are awarded to the Pookyball used for a prediction, at the moment when the player claims Leaderboard rewards. 

PXP allow players to Level-Up Pookyballs. 

Rare, Epic and Legendary Pookyballs have more Levels, but their higher earning of PXP means they'll be, on average, higher level than a lower tier ball.

| Rarity    | PXP Multiplier |
| --------- | -------------- |
| Basic     | 1              |
| Common    | 1              |
| Rare      | 2              |
| Epic      | 4              |
| Legendary | 8              |
| Mythic    | 16             |
