# NFT Reactor and Cell System

Reactors and Cells are a core part of the XPR progression system in Roach Racing Club. They allow players to unlock additional XPR rewards, boost progression, and access expanded earning mechanics.

\
**Reactor**

The Reactor is a special NFT Device that can be obtained through Missions or purchased in the Shop. Each Reactor contains 4 activation slots, and every slot can be filled once using a Cell.

When activated, a Reactor provides significant gameplay and progression benefits:

* Unlocks XPR in Arcade mode (your first 3 Arcade races every day give boosted XPR rewards):

1 Run: Equals 5 rounds.

Daily Limits: First 3 runs → full XPR. Subsequent runs → 5% of normal. Players race together but XPR is awarded individually based on their battery.

Each player receives their own XPR pool depending on their battery tier.

* Enhances Daily Rewards and enables daily XPR earnings
* Unlocks partner rewards
* Has future ecosystem utility tied to upcoming phases

**Important rules:**

* Reactor cannot be transferred
* You can own only 1 reactor
* No time limit between activations

**Reactor Evolution:**

The Reactor evolves after all 4 slots are filled.\
Its final form depends entirely on the tiers of Cells used during activation.\
Higher-tier Cells → stronger evolved Reactor.

***

**Cells**

Cells are in-game NFT consumables used to activate the Reactor.\
They can be obtained from Missions or purchased in the Shop.

Each Cell:

* has its own power tier
* determines the amount of instant XPR you receive
* defines the strength of your daily and Arcade rewards
* activates the Reactor for 7 days
* is burned after use
