Bugs are game flaws that can be triggered either intentionally or unintentionally by players. The term "bug" may refer to:
- an exploit; a bug or unintended feature of gameplay that is deliberately and knowingly used by the player to gain an advantage; or
- a glitch; an unintentionally-triggered game flaw that generally does not affect gameplay.
While exploits are usually frowned upon by other users, glitches are generally more tolerable.
