## Dataset Overview

This dataset contains **real human gameplay** from Arkadium's gin rummy platform, providing researchers and developers with high-quality training data for game AI, reinforcement learning, and computer vision applications. All hands include screenshots.

**RAW data only.** The primary dataset is a single raw ZIP archive (`.pbn`/`.webp`). Parquet files in `data/` contain only 10 example records for the HuggingFace Dataset Viewer and are not a full export. We do not provide a full Parquet version.

**Totals (selected subset):** 10,000 matches, 686,403 screenshots, ~23.62 GB compressed ZIP size. The dataset is capped at 10,000 unique hands with screenshots and packaged into a single archive.

## Use Cases

- **Game AI Training**: Train models to predict optimal draws/discards using supervised learning on human gameplay.
- **Reinforcement Learning**: Use as demonstration data for imitation learning or to initialize RL agents.
- **Computer Vision**: Card/board state recognition, meld detection, and UI state extraction from images.
- **Strategy Analysis**: Study human decision-making patterns, draw/knock timing, and deadwood management.

### Game Log Format (`.pbn`)

Each `.pbn` file contains a complete gin rummy hand record in a human-readable format:

```
[FF "4"]
[DT "2025.08.15"]
[GN "ginrummy"]
[PC "arkadium.com"]
[GameplayId "132069239"]

[Player1 "p1"]
[Player2 "p2"]

[Hand "3:6"]
[GameScore "63:0"]
[Dealer "2"]
[Deal "C2 S3 C5 D6 S6 H7 C8 C9 DQ SQ, HA DA C3 D4 H6 C6 S8 CJ SJ DK"]
[Upcard "HQ"]
[Score "0:25"]

[Play]
1. 1 picks HQx
2. 1 discards H7
3. 2 picks D2
4. 2 discards DK

<summary><b>Parquet Preview (10 records)</b></summary>
<br>
Parquet files in `data/` are **only a 10-record preview** for the HuggingFace Dataset Viewer.  
They exist **exclusively for demo/browsing** and **do not represent the full dataset**.  
All primary data is in the raw ZIP archives above, and no full Parquet release is provided.

### Quick Start (Preview)

### Installation

```bash
pip install datasets pillow
```

### Load the Preview

```python
from datasets import load_dataset

# Load preview with screenshots (10 records)
ds = load_dataset("ArkadiumInc/ArkadiumGinrummy", "gamelogs_with_images")
```

### Basic Usage

```python
# Access a single hand
hand = ds["train"][0]

print(f"Players: {hand['player1']} vs {hand['player2']}")
print(f"Date: {hand['event_date']}")
print(f"Score: {hand['score']}")
print(f"\nMoves:\n{hand['moves']}")
```

### Working with Screenshots

```python
from PIL import Image
import io

# Get a hand with images
hand = ds["train"][0]

print(f"This hand has {hand['num_images']} screenshots")

# Display the first screenshot
if hand['images']:
    img = Image.open(io.BytesIO(hand['images'][0]))
    img.show()
```
