-Layer 1 represents the default, official environment within [Algodoo](/wiki/Algodoo). It typically features a simple sky and ground, providing a foundational canvas for [simulation](/wiki/Simulation) and [physics](/wiki/Physics) experiments.
-## LAYER 4
-[Layer 4](/wiki/Layer_4) is another conceptual, fan-made environment, often referred to as the "Glitching Sky." Accessing this layer is considered an even greater challenge than reaching [Black Sky](/wiki/Black_Sky) or [Color Sky](/wiki/Color_Sky), requiring extensive exploration and dedication within [Algodoo](/wiki/Algodoo). Its visuals are typically characterized by a muted grey background with small, fragmented, glitch-like patterns, reflecting its name.
-## LAYER 5
-[Layer 5](/wiki/Layer_5) is another conceptual, fan-made environment, often described as having a distinctive red sky. It is believed to be accessible from [Layer 4](/wiki/Layer_4) and is notorious for featuring "crashers"—entities that, upon contact, can cause the [Algodoo](/wiki/Algodoo) simulation to abruptly terminate, adding a significant risk to its exploration.
