# Legacy: Previous Game Concept

Trade Clash originally launched as a reflexive prediction market powered by six AI world leaders. The game has since pivoted to a [sealed-lot Polymarket auction](/tradeclash/game-design/core-mechanics.md). This section preserves documentation from the original concept.

## What Changed

|                   | Previous Concept                        | Current Concept                             |
| ----------------- | --------------------------------------- | ------------------------------------------- |
| **Core mechanic** | Predict AI leader behavior              | Bid on hidden Polymarket portfolios         |
| **Player action** | Fast-swipe YES/NO on AI decisions       | Sealed bids across 3 streets                |
| **Game length**   | 3-hour cycles, 7-day tournaments        | \~3 minutes per lot, continuous rooms       |
| **Opponents**     | AI leaders (6 personalities)            | Other players (2-4 per room)                |
| **Data source**   | Polymarket odds + Hivemind crowd signal | Real Polymarket positions bundled into lots |
| **Win condition** | Predict correctly                       | Buy the lot below trueValue                 |

## What Stayed

* **Polymarket** as the data source
* **3D globe** as the primary interface
* **Base blockchain** for on-chain settlement
* **Skill-based competition** as the core identity
* **$SIM** as the reward token

## 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://serotolabs.gitbook.io/tradeclash/about-trade-clash/legacy.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.
