Initials can be played by any number of players, including one.
The object is to find names of well-known people whose initials match two randomly chosen letters. The letters can also be the same.
In competitive versions of the game, the player (or team) to find the most names in a given time wins.
A personal confession: the author of this description has for many years played this game on his own as a good luck ritual during half-time breaks of his favorite team's games, and has
contributed to many comebacks by finding at least five names for a difficult pair of letters :)
