# What is Cash City?

<figure><img src="/files/4AGfv1tlkYBRVqWJ0HlK" alt=""><figcaption></figcaption></figure>

Cash City is a competitive Trading Firm simulator built on Solana. You play as a CEO running up to 15 Firms, hiring Interns to work the Trading Floor, and earning a proportional share of the network's daily $CASH token emissions.

The more efficient your operation, the bigger your slice.

## The Core Loop

The game follows a simple but deep cycle:

**Buy a Firm** → **Open Intern Packs** → **Seat Interns at Desks** → **Earn $CASH** → **Claim** → **Repeat**

1. You purchase a firm for **1 SOL**, which gives you 8 desk slots and 1 free Intern Pack.
2. You open Intern Packs (200 $CASH each) to pull Interns of varying rarity and Efficiency.
3. You place Interns at desks on your Trading Floor to start generating $CASH.
4. Every 15-minute epoch, the network distributes $CASH proportionally based on your Efficiency share.
5. You claim your accumulated $CASH and improve your operation by searching for rarer Interns, and upgrading your Firm level.

The competitive element is central. Your earnings aren't fixed — they're relative to every other player in the network. If you stop investing and the network grows around you, your share shrinks. If you upgrade while others hold, your share grows.

| --------------- | ------------------------------------------------------------- |
| **Firms**       | Your business. Buy for 1 SOL, upgrade for more desk slots.    |
| **Interns**     | Your workforce. Pulled from gacha packs. Rarity = Efficiency. |
| **Advisors**    | Global boosters. Percentage buff across all your Interns.     |
| **Consumables** | Temporary 24h boosts applied to individual Interns.           |
| **$CASH**       | The in-game token. Earned through emissions, spent on packs.  |
| **Efficiency**  | The stat that determines your share of emissions.             |
| **Epochs**      | 15-minute distribution cycles for $CASH emissions.            |
