Arts and Entertainment of the Twelve Colonies (TOS)
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Music and Dance
The Colonials appear to have an appreciation for singing. The Tucana singers on Carillon perform for the Colonial patrons, and Starbuck judges their talent to be exceptional (and potentially very lucrative). A sparsely clad dancer performs on Carillon, earning the appreciation and even the occasional cubit thrown her way (Saga of a Star World).
The "Rope Dance"
Revelers aboard the Rising Star participate in a dance involving strands of rope. The dance appears to be able to be performed individually (War of the Gods, Part II), in pairs (War of the Gods, Part II), and as a group (War of the Gods, Part I).
Sports and Games
Games of chance are popular. The most common amongst the pilots is Pyramid, a card game. At the chancery on Carillon there appear to be a variety of games, with the odds stacked heavily in favor of the patrons in order to get them to stay for dinner.
For those who do not wish to partake in games of chance, there are also other recreational games, such as those in Galactica's rejuvenation center (Fire in Space) and the three-dimensional chess set in Adama's ready room (Saga of a Star World). Compartment bulyarks is one of the games in the rejuvenation center. The game resembles indoor shuffleboard. Boxey excels at the game, defeating Athena at it repeatedly (Fire in Space).
7-11 is an unidentified game mentioned by Boomer. After Lieutenant Boomer chastises Cadet Cree for being too close in the formation after launching from Galactica, Cree replies that his instructor ordered him to always keep tight– to which Boomer replies that Cree's instructor is "back at the base playing 7-11" (The Gun on Ice Planet Zero, Part I).
