"Experience points" — gathered during some games to gain upgrades.
Usage
Upgrade — Game mechanics of providing better possibilities to the player.
Mechanic — A subsystem of the game that regulates interaction with a game state.
RPG — Role-Playing Game, a game where the main focus is assuming the role of a fictional character.
Most often there is a choice of upgrades for a player who is leveling up.
XPs are a popular mechanic in RPGs (and computer versions of those, cRPGs). The name usually fits the narrative of the game where the player controls a character (or characters) that are developed during the course of the game.
You don't have to use stories to advantage from XP-like points in game design. In abstraction, they are just points that usually are:
- means toward the further target,
- impossible to be taken away from player,
- gained with both successes and failures.
These are the qualities with quite a positive spin as they are not very punishing toward players and might soften the competitive edge of the game. If you spread rewards along such a point track, you tap into a classic design solution of XP.
