Other forms: endgames
An endgame is the very last part of a strategic game, like chess or backgammon. The last few moves you make in your chess game are your endgame.
Although the term endgame doesn't have a formal definition in chess, it's long been used by players to describe what happens when very few pieces are left on the board. One interesting thing characteristic of a chess endgame is that the king, which spends most of the game being protected by other pieces, becomes much stronger. From the chess meaning, endgame is also used figuratively to mean "end stages of negotiation."
