# How to add special rules to your Gacha using .CSV file
You can add special rules for specific wallet addresses such as **allowlists** to restrict access, **discounted plays,** and **free plays** by uploading a .CSV file with three columns:
* **address** = wallet address of users you wish to apply rule to
* **playcount** = number of times each address can play
* **price** = the price user can play for:
* blank = current set price
* 0 = free
The easiest way to create a .CSV file is to do so in a spreadsheet such as google sheets or Excel.
**Example:**
Once you have filled out your spreadsheet, you can export it as a .CSV file as shown below:
**Google Sheets:** File -> Download -> Comma Separated Values (.CSV)
**Microsoft Excel:** File -> Export -> Change File Type -> CSV (Comma Delimited)

## 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:
```
GET https://docs.dokidoki.com/tutorials/how-to-add-special-rules-to-your-gacha-using-.csv-file.md?ask=&goal=
```
`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.
