⚗️ What is Emoji Alchemy?

Emoji Alchemy is a puzzle game based on the mathematical concept of String Rewriting Systems (or Term Rewriting Systems). In this game, emojis act as "symbols" and the game rules act as "production rules." Your goal is to transform a starting sequence of emojis into a specific target sequence by applying these rules in the correct order.

📘 How to Play

1. Tap to Select

Tap any emoji to see the available actions. If an emoji can be changed on its own, a blue CHANGE button will appear above it.

2. Merge with Neighbors

If an emoji can be combined with the one immediately to its right, a yellow MERGE button will appear when you tap it. Be careful, some combinations lead to dead ends!

🧠 Computer Science Concepts

This game visualizes core concepts of computer science and logic:

  • Order of Operations: In many levels, the result changes depending on which rule you apply first. This teaches the concept of "non-confluence" in rewriting systems.
  • Resource Management: You must manage the population (symbols) carefully to avoid reaching a "dead state".
  • Formal Grammars: The game mechanics are similar to Context-Free Grammars or Semi-Thue Systems.
