## Geographic Reference Cards

The station includes geographic reference photo cards for all 23 cities. Each card shows:

- **City photo** - Iconic landmark or cityscape
- **Geo-tags** - Broad geographic categories (e.g., Delta, Peninsula, Major River, Highland)
- **Description** - Specific geographic details about the city's location

**How players solve it:**
1. Read clue (uses broad terms like "delta" or "peninsula")
2. Scan reference cards for matching geo-tags
3. Multiple cities may share a tag - read descriptions to narrow down
4. Each clue uses 1-2 geo-tags that uniquely identify one city

**Example:** Clue says "delta capital where a river empties into the Gulf of Thailand"
- Scan for `Delta` tag → finds Cairo, Bangkok, Hong Kong
- Add "Gulf of Thailand" → only Bangkok matches
