[Term] Round [Description] 
Usually refers to a particular game design in where the overall challenge must be overcome across more than one (up to infinity) identical or near-identical attempts. The core challenge and rules remain the same, and changes to gameplay across rounds is limited to an increase in stakes and/or to difficulty. Typically seen in fighting games (i.e. "rounds" during a martial arts match), this concept is also often seen in puzzle games, party games, and titles that are driven by mini-games. They can also be localized into specific gameplay such as a boss encounter that is broken into rounds.
