# Referral Program
Cash City is **permanently invite-only**. There is no public signup, no open registration, and no way to bypass the invite system. Every new player enters through someone else's invite code — and the person who shared that code earns rewards.
***
## How It Works
Every player in Cash City has a unique invite code visible in their profile. Share it anywhere — X, Discord, DMs, group chats — and when someone uses your code to enter the game, you're linked as their Referrer.
### Multi-Tier Rewards
Cash City uses a two-tier Referral system:
| Tier | Relationship | Reward |
| ------ | ----------------------------------------- | ---------------------------- |
| Tier 1 | Direct invite (you → them) | 5% of all $CASH they claim |
| Tier 2 | Their invites (you → them → someone else) | 2.5% of all $CASH they claim |
When someone you invited brings in another player, you earn a second-tier reward from that downstream player's activity as well. This creates a compounding incentive to invite active players who will themselves invite others.

## Maximising Your Referral Earnings
Your Referral code is most valuable when it reaches people who will be **active, long-term players** — not one-time visitors.
* **Share on X with context.** Don't just post your code. Show your earnings, your Intern collection, or your Firm setup. Give people a reason to want in.
* **Target crypto communities.** Players who already have Solana wallets and understand on-chain gaming will convert at a much higher rate.
* **Build a network.** Your Tier 2 earnings mean the best Referral is someone who will also actively invite others. Inviting one crypto influencer can be worth more than inviting 100 casual players.

## Viewing Your Referrals
Your referral dashboard in the Office shows your total invites, active referred players, and accumulated referral rewards across both tiers.

## 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.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

`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.
