# Slot System

Players can own up to 6 roaches in Roach Racing Club. For each new Roach, players need to purchase a slot and then the Roach itself. 

Each subsequent slot and roach is one tier higher than the previous one. Higher tier Roaches unlock new body parts, colors, and cryptocurrencies.

Each slot contains a generator that produces energy for charging Roaches. Having multiple slots (and thus multiple generators) speeds up the charging process.

**Roach Tiers**

| **Slot/Tier** | **Slot Cost (TRAX)** | **Roach Cost (MTGN)** |
| ------------- | -------------------- | --------------------- |
| 1             | 0                    | 0                     |
| 2             | 10                   | 1,000                 |
| 3             | 25                   | 5,000                 |
| 4             | 100                  | 25,000                |
| 5             | 300                  | 100,000               |
| 6             | 1,000                | 250,000               |

**Benefits of Multiple Slots**

1. Faster Charging

Each slot contains a generator that produces 50 energy per hour. Having multiple slots (generators) speeds up the charging process:

* 1 generator: 1 roach charges in 2 hours
* 2 generators: 1 roach charges in 1 hour
* 3 generators: 1 roach charges in 40 minutes

If multiple roaches are charging simultaneously, they share the charging speed.

2. Roach Variety

Having multiple roaches allows players to:

* Race with roaches of different Moods (Bullish or Bearish) that match current market conditions
* Choose roaches linked to different cryptocurrencies based on their preferred volatility
* Enter more races without waiting for recharge
* Unlock higher-tier roaches with unique visuals and traits

**Roach Asset**

Each roach is born tied to a specific cryptocurrency asset such as BTC, ETH, XRP, etc. This determines what crypto chart will be used to control the roach during the race.

Roaches of higher Tiers have more cryptocurrency options to be assigned at birth or upon Reroll:

* 1st slot – $BTC, $ETH, $LTC
* 2nd slot – $XRP, $BNB, $TRX + previous
* 3rd slot – $SOL, $ADA, $POL + previous
* 4th slot – $TON, $LINK, $DOT + previous
* 5th slot – $HYPE, $PENGU, $WIF + previous
* 6th slot – $TRUMP, $PEPE, $DOGE + previous

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
