# Reward Simulator

The Reward Simulator is a practice tool that helps users understand how UCPRA rankings and rewards work — without risking real funds.

## What It Does

Users can configure a mock market scenario and instantly see how rankings and rewards would be distributed. This provides full transparency into the reward algorithm before committing real entry fees.

## How to Use It

    C --> D[Set Settlement Price]
    D --> E[View Full Rankings & Rewards]
```

### Step 1: Configure Market

* Choose number of participants (e.g., 50, 100, 500)
* Set entry fee amount

### Step 2: Enter Predictions

* Add sample predictions at different price levels
* See how distance from settlement price affects rank

### Step 3: Set Settlement Price

* Choose the oracle price that "settles" the mock market
* Watch all rankings recalculate instantly

### Step 4: View Results

* See complete ranking of all participants
* View which predictions are Rankers vs Bucket Winners vs non-winners
* See exact reward amounts for each position
* Understand the 51% in-the-money threshold in practice
