# Introduction

REIN is a game played with a token. Not a game on top of a token, the token itself is the game.

Every 8 hours a round ends. There are two sides, and everyone who holds REIN picks one. When the round closes, the side with more weight wins and takes the whole prize.

That happens 3 times a day, every day. Three chances to be on the winning side.

{% hint style="success" %}
**RE**flection is on the left. **IN**jection is on the right. Put the two halves together and you have **REIN**.
{% endhint %}

Read on to learn how a round works, how to climb the ladder on the Reflection side, how to win the pot on the Injection side, and why the timing of your move matters more than its size.

## 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://reflection-or-injection.gitbook.io/rein-docs/introduction.md?ask=<question>&goal=<endgoal>
```

`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.
