The hills provide the battleground where Redcode programs compete for supremacy. Some are round robin, where warriors fight each other in one-on-one battles. Others are mêlée (multi-warrior) where all warriors battle simultaneously.
There are two main types of hill, KotH and infinite. KotH hills are a fixed size; after each submission the weakest warrior is pushed off. Warriors are never pushed off infinite hills, but all submissions are made public. The beginners' hill and multi-warrior hill are recommended for beginners.
