The first video game about Skirmish mode was released on March 28, 2007.
At the core skirmish mode is essentially "a single game" mode where such is possible, such as quick battle, single puzzle, etc. where winning the game usually does not give anything on long term except maybe a replay recording, record on score board, or similar.
