What is the total number of elements in Little Alchemy 2?

In Little Alchemy 2, the total number of elements you can discover is 720. This includes all base elements, combinations, and hidden items. To track your progress and see how many elements you've unlocked, follow these steps:

1. Open the Encyclopedia: In the game, click on the book icon (usually located in the top-right corner of the screen). This opens the Encyclopedia, which lists all the elements you've discovered so far.

2. Check Your Progress: At the top of the Encyclopedia, you'll see a counter like "Discovered: X/720". This shows how many elements you've found out of the total 720.

3. Find Missing Elements: If you're missing some elements, the Encyclopedia will display grayed-out icons for the ones you haven't discovered yet. Hover over these icons to see hints about how to create them.

4. Experiment with Combinations: To unlock new elements, combine existing ones. For example:
- Fire + Water = Steam
- Earth + Fire = Lava
- Air + Water = Rain

5. Use Hints Wisely: If you're stuck, you can use the hint system (lightbulb icon) to get suggestions for new combinations. Hints are limited, so use them strategically.

6. Explore Hidden Elements: Some elements are hidden and require specific or less obvious combinations. For example:
- Time + Life = Human
- Human + Tool = Engineer

By systematically combining elements and using the Encyclopedia to track your progress, you can work toward discovering all 720 elements in Little Alchemy 2. Good luck!
