How Infini's Combination Engine Works

The Engine Behind the Magic

Ever wondered how Infini decides that Water + Fire = Steam or that Earth + Energy = Crystal? This post goes behind the scenes to explain the combination engine that powers every discovery.

Static Data, Not AI

Unlike some similar games that use AI APIs to generate combinations on-the-fly, Infini uses a completely static, pre-generated dataset. Here's why:

| Approach | Pros | Cons | |----------|------|------| | AI API (real-time) | Unlimited combos | Slow, costly, unpredictable results | | Static dataset | Instant, free, consistent, offline | Fixed number of elements |

We chose the static approach because:

1. Speed — combinations resolve in under 1 millisecond, with zero network latency
2. Cost — no API calls means no per-user costs, keeping the game 100% free
3. Consistency — every player gets the same recipes, enabling fair sharing and guides
4. Offline play — the entire game works without an internet connection

How Recipes Are Structured

Every combination in the engine follows this format:

Input A + Input B → Result (emoji, category, tier)

For example:

{
  "Water+Fire": {
    "result": "Steam",
    "emoji": "♨️",
    "category": "natural",
    "tier": 1
  }
}

The combination key is order-independent — Water+Fire and Fire+Water always produce the same result.

The Category System

Every element belongs to one of 9 categories, which helps organize discoveries and enables filtered browsing:

| Category | Examples | Description | |----------|----------|-------------| | 🔵 Element | Water, Fire, Earth, Wind | The four base building blocks | | 🌿 Natural | Steam, Rain, Mountain | Nature phenomena and formations | | 🏗️ Artificial | Brick, Glass, Paper | Human-made materials and objects | | ✨ Magical | Philosopher's Stone, Alchemy | Mystical and legendary items | | 💻 Tech | Computer, Internet, Robot | Technology and digital concepts | | 🍕 Food | Bread, Soup, Chocolate | Edible items and dishes | | 🐾 Animal | Fish, Bird, Dragon | Living creatures | | 📍 Place | City, Ocean, Space | Locations and environments | | 💡 Concept | Time, Love, Music | Abstract ideas |

The Tier System

Tiers represent how many combination steps an element requires from the base elements:

• Tier 0: Water, Fire, Earth, Wind (starting elements)
• Tier 1: Direct combinations of Tier 0 elements (e.g., Steam from Water + Fire)
• Tier 2: Requires at least one Tier 1 ingredient
• Tier 3+: Deep discoveries requiring multi-step crafting chains

Higher tiers generally correspond to rarer and more interesting discoveries.

Performance & Architecture

Infini is built as a Progressive Web App (PWA) with these technical characteristics:

• Framework: Next.js with static site generation
• State management: Zustand for client-side game state (persisted to localStorage)
• Rendering: All 400+ recipe pages are pre-rendered at build time
• Bundle: The entire combination dataset is ~50KB gzipped
• Offline: Service Worker caches all assets for offline play

What This Means for Players

Because the engine is static and deterministic:

• ✅ Guides and tips from other players will always be accurate
• ✅ Your progress is saved locally — no account needed
• ✅ The game loads instantly even on slow connections
• ✅ You can install it as an app on your phone or desktop
