# Glossary

* **Brier score.** A strictly proper scoring rule that penalizes the squared difference between declared probabilities and the realized outcome. Lower is better.
* **Buy-in.** The amount of $SMILY a player stakes to enter a room. The pot is the sum of all buy-ins.
* **Chop.** Splitting a prize equally among players tied for a paying position.
* **Commit-reveal.** A two-step scheme where a hashed commitment is submitted first and revealed later, so no one can see or change answers in between.
* **Decathlon of prediction.** The signature identity of Smily: many domains, many questions, total skill, zero edge.
* **Frozen oracle snapshot.** Resolution data captured at a defined, published timestamp, so no one can front-run a price tick and all players resolve against the same data.
* **Heads-Up.** A two-player, winner-takes-all room.
* **Home Game.** A private room created and configured by a player, joined by invite.
* **Logarithmic score.** A strictly proper scoring rule that rewards calibration sharply and punishes confident error harshly. Unbounded below. A possible future high-variance mode.
* **Optimistic oracle.** A resolution mechanism where an outcome is proposed, a challenge window opens, and disputes escalate to a vetted vote or decision.
* **Player pool.** The shared set of players available for matchmaking across the hub.
* **Pool Charter.** The set of rules that decides which questions are allowed into a room, how domains are balanced, and how every outcome is resolved.
* **Pot.** The total $SMILY staked in a room, split 97% to winners, 2% burned, 1% operating revenue.
* **Proper scoring rule.** A scoring function maximized in expectation by reporting your true probabilities. The mathematical guarantee of a skill game.
* **Proximity scoring.** Scoring a numeric guess by its distance to the realized value. Not incentive-compatible in a pot, so used only for marked headline questions.
* **Push.** A returned-stake outcome in a Heads-Up tie, minus the burn.
* **Quick Match.** The auto-matching system that seats a player into a room at their chosen tier and format from the shared player pool.
* **Sit and Go.** A room that starts as soon as it fills, with no fixed start time.
* **Smily Points.** A cosmetic 0 to 1000 display of a player's score, monotonic in the Brier penalty, where higher is better. It never changes who wins.
* **Spin and Go.** A three-player hyper-fast room with a randomly drawn prize-pool multiplier.
* **VRF.** Verifiable randomness, used for provably unbiased seating and multipliers.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://smily.gitbook.io/smily-docs/glossary.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.
