Chess has six different piece types, and each one moves according to fixed rules.

The longer version

Each type is defined by how it moves rather than by what it looks like: the king steps one square, the rook travels along ranks and files, the bishop stays on one colour, the knight jumps in an L, the queen combines rook and bishop, and pawns advance and capture differently. Because pawns never move backwards, the position gradually freezes into a shape.

The set is small enough that experienced players recognise patterns instantly, yet the number of possible games is far larger than the number of atoms in the observable universe. A pawn reaching the far rank can be exchanged for any other piece, which is the usual way material advantage is converted. Computer analysis changed opening preparation but never the movement rules.
