Expansion for Base-game games are sets of additional components and rules for expanding on an original base game. An expansion cannot be played alone; they must be used in conjunction with the base game.
Expansions for base games can be found in most of the game entries on BGG. You will find them in the "Information" section, under "Expanded By". You can also find expansions under the "Linked Items" column.
