# Game Participation Guide
## Overview
MemeDice's investment equity system allows anyone to become the game's**liquidity provider (LP)**and inject tokens into the pool, sharing the game's profits and losses with other shareholders.
> 💡 **Core concept**: players lose = shareholders win, players win = shareholders lose. In the long run, due to the house edge, the pool tends to grow.

## Quick Start
### 1. Go to the investment page
Visit any MemeDice game (such as `xxx.dapp.meme`), click the **"💰 Investment"** tab in the top navigation bar.
### 2. Connect wallet
If your wallet is not connected yet, click the **"Connect Wallet"** button on the page. Make sure your wallet network matches the game's network.
### 3. Deposit tokens
1. Enter the amount of tokens you want to deposit in the input box
2. If this is your first deposit, you need to click **"Approve"** to authorize the tokens first
3. After authorization is complete, click **"Deposit Equity"** Deposit tokens
4. Confirm the transaction in your wallet
5. After the transaction is confirmed, you will become a shareholder of this game
### 4. View earnings
After depositing, you can view in real time on the page:
| Information | Description |
| --------------------- | ------------------------------------------------------------------------------------------------- |
| **Your share** | Your proportion in the pool |
| **Current value** | The amount of tokens your share corresponds to (may be higher or lower than the amount deposited) |
| **Total pool amount** | The total amount of tokens currently in the pool |
| **Pool capacity** | The maximum capacity limit of the pool |
### 5. Withdraw earnings
When you want to exit, click **"Withdraw"** button to withdraw all your shares with one click.
> ⚠️ **Note**: Withdrawals are full withdrawals only; partial withdrawals are not supported. Platform fees and owner fees will be deducted when withdrawing.
***
## Key Concepts
### House Edge
Each bet includes fees (platform fee + owner fee), which means that statistically the pool tends to grow over the long term. However, in the short term, a series of large winning bets may cause the pool to shrink temporarily.
### Share Calculation
MemeDice uses **Vault-style global accumulator mode**, which is a gas-efficient way to calculate shares:
* When depositing: calculate the number of shares you receive based on the current total pool amount and total shares
* When withdrawing: calculate the number of tokens you can withdraw based on the proportion of your shares to the total shares
For the detailed share calculation mechanism, see [Detailed Explanation of the Shareholder System](/dapp.meme-en/provide-liquidity-lp/detailed-explanation-of-the-shareholder-system.md).
### Risk Warning
> ⚠️ **Investment involves risk**
>
> * When players win, the pool decreases, and the value of your shares will drop
> * In extreme cases (a series of large winning bets), you may lose most of your principal
> * When the pool balance is insufficient, large bets may be rejected, but this will not affect the shares of existing shareholders
> * Please only invest amounts you can afford to lose

## Pool Status
The investment page will display the pool's real-time status:
```
Pool progress bar
[████████████░░░░░░░░] 60%
Current balance: 600,000 USDT / Maximum capacity: 1,000,000 USDT
```
* **Current balance**: the total amount of tokens in the pool
* **Maximum capacity**: the pool cap set by the game creator (`maxPoolCap`)
* **progress bar**: visually shows the pool's utilization rate
When the pool reaches maximum capacity, new deposits will be rejected.
