🔄 Merging System Guide

Master the binary progression system - the key to power in Plant Brainrot Simulator!

📐 The Merging Formula

SEEDS REQUIRED FORMULA

Seeds = 2(Star Level - 1)

Every star level doubles the required seeds. This is called binary progression.

💡 Pro Merging Strategies

🎯 Focus on One Plant Type

Instead of buying many different seeds, focus your gold on one plant type. This makes merging faster and more efficient. A garden full of Tomatoes merges quickly into high-star Tomatoes.

📊 Quality Over Quantity

One 5★ plant (16 seeds worth) deals 10.5x damage compared to a 1★. That's more efficient than having 16 separate 1★ plants! Always merge up as soon as possible.

🔄 Merge During Combat

Don't wait for waves to end! Keep buying seeds and merging during battles. This ensures you're always progressing and your garden stays organized.

🗂️ Keep Garden Organized

Group plants by star level in your garden. This makes finding merge pairs instant and prevents you from missing opportunities.
