📚 RNGsmith Documentation

🎲 What is RNGsmith?

RNGsmith is a probability distribution design and simulation tool. It helps developers, game designers, and data explorers create and test custom probability curves — especially useful for loot systems, gacha mechanics, or reward distributions.

⚙️ How It Works

• Generator: Define a min, max, and target average to create a probability distribution.
• Simulator: Run N-round trials using the distribution to evaluate how closely the output matches your expected average.
• Exporter: View and copy the distribution in TypeScript or CSV formats for direct integration into your project.

📐 How Is the Distribution Calculated?

RNGsmith uses an inverse-square weighting algorithm to bias values around the target average. This makes numbers closer to the average more likely, while still respecting the min and max bounds.

Example: Target average = 6 with range 1–10 will generate a curve where 5, 6, and 7 are more likely than 1 or 10.

💡 Use Cases

• Gacha and lootbox balancing
• Daily rewards with increasing rarity
• Game jam simulations and fair randomness
• Behavioral reward design (education, gamification)
