# Odds Boosts

<img src="/files/wc23rvbZiOZU1JpUH1uu" alt="" data-size="line"> **A Sharper Edge on Sports**

Every sportsbook builds a margin into its odds. Your stake in $SPIN cuts it, two ways.

**Boost tokens:** your tier drops fresh Odds Boost tokens each week, one for a Shrimp, twenty for a Whale. Attach one to a bet and the payout jumps by 10 to 25%, with the boost strength and stake cap shown right on the bet slip.

**The permanent $SPIN uplift:** any sportsbook bet placed in $SPIN pays extra on top, boost or no boost, at every tier. A market priced at 1.90 pays out like 1.99 when the stake is $SPIN.

The more you hold, the less the house holds back.

## 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.chainspin.com/rewards/odds-boosts.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.
