How do I combine Life and Stone in Doodle God?

To combine Life and Stone in Doodle God, you need to follow a specific sequence of steps. First, ensure you have both the Life and Stone elements unlocked. Life is typically created by combining Energy and Swamp, while Stone is a basic element that is often available early in the game. Once you have both elements, simply drag Life onto Stone or vice versa in the game interface. This combination will create the Egg element. The Egg is a key element that can be used in further combinations, such as creating a Lizard by combining Egg with Swamp or creating a Bird by combining Egg with Air. This process is part of the game's progression, where combining elements logically or thematically leads to the discovery of new items. Experimenting with different combinations and revisiting earlier elements with newly unlocked ones is a good strategy to advance in the game.
