Easter egg

Easter eggs are usually hidden surprises or tricks. They are small surprises programmers add to their media for players to uncover, much like chocolate eggs in a real-life Easter egg hunt. Many Easter eggs are purely for entertainment. Some examples include hidden names or faces of programmers, references to other games, or messages for the player.

Easter eggs should not be confused with glitches, cheats, or techniques. Many do not alter gameplay at all, and are added on purpose.
