⚔️ Battle Rules

The rock with the highest scratch score wins!

Scratch scores are based on the Mohs Hardness Scale - they tell us which rocks can scratch others.

🎮 How to Play

• Select a rock card from your hand
• Optional: Use a Process Card to transform your rock and potentially increase its scratch score!
• Click Battle to see who wins

🔄 Rock Transformations

Use process cards wisely:

• 🔥 Heat & Pressure creates metamorphic rocks (can make rocks harder!)
• 🌊 Weathering breaks rocks into sandstone
• 🌋 Melting turns rocks into new igneous rocks

💡 Strategy Tips

• Granite → Gneiss (scratch 6→7) is powerful!
• Transform weak rocks before battle
• Watch the science explanations to learn!
