Cave Temples of Mahabalipuram: The Cave Temples of Mahabalipuram are located on the hillock of town, overlooking the Coromandel Coast of the Bay of Bengal in Kanchipuram District in Tamil Nadu, India.  Also called mandapas or rock-cut caves, they are sanctuaries or temples covered with bas-reliefs.  The earliest period of use of these caves as sanctuaries is traced to Buddhist and Jain periods.  They were excavated on rock faces which were cut and then carved using chisel and iron mallet.  Of the eleven mandapas or caves seen in Mahabalipuram, the most notable are the Varaha Cave Temple, Krishna Cave Temple, Panchapandava Cave Temple, and the Mahishasuramardini mandapa.  They are cut and decorated with panels in the Mamalla style of the Pallava period in the 7th century.  They are differentiated from the Adiranchanda cave temples which are dated to the Mahendraverman period of the 8th century.  Remnants seen in the caves also indicate that they were plastered and painted when built.  One of the most impressive sculpture panels, bas-reliefs, carved on the walls in the caves is that of the goddess Durga (a form of goddess Shakti) who killed Mahishasura the buffalo-headed demon which has a natural beauty with elegance of sense of movement, and this bas-relief panel in the Mahsisuramardhini Cave Temple is considered a masterpiece of Indian art.  Many of the caves of the Pallava period have remained incomplete.  The procedure in creating these caves involved creation of a smooth rock face, then cutting columns through the polished rock faces of required size and then carving bas-reliefs on the walls of the cave.  Some of the cave temples are covered by the UNESCO inscription while others are not, such as the Koneri Mantapa, the Yali Mantapa, and the Kotikaal Mantapa.  All caves here with simple plan and elegant architectural style, and have no deities deified in the sanctum sanctorum.  It is one of the Group of Monuments at Mahabalipuram that were designated as a UNESCO World Heritage Site since 1984 under the heading mantapas.

Astar (game): Astar is a two-player abstract strategy board game from Kyrgyzstan.  It is a game similar to draughts and Alquerque as players hop over one another's pieces when capturing.  However, unlike draughts and Alquerqe, Astar is played on 5x6 square grid with two triangular boards attached on two opposite sides of the grid.  The board somewhat resembles those of Kotu Ellima, Sixteen Soldiers, and Peralikatuma, all of which are games related to Astar.  However, these three games use an expanded Alquerque board with a 5x5 square grid with diagonal lines.  Astar uses a 5x6 grid with no diagonal lines.

Akkana Madanna Caves: Akkana Madanna cave temple is a rock-cut cave temple in Vijayawada of the Indian state of Andhra Pradesh.  It is situated at the foothill of the Indrakeeladri temple known for Kanaka Durga Temple.  It is one of the centrally protected monumemts of national importance.  It was built in the 17th century, though the caves themselves date from the 6th and 7th centuries.  There is another cave nearby which is dated from the 2nd century BC.  The Trimurti of Brahma, Vishnu and Shiva is hosted there.

Sua Ghin Gnua: Sua Ghin Gnua is a two-player abstract strategy board game from Thailand, formerly known as Siam.  Another name for the game is Tigers and Oxen.  It is a hunt game played on a 5x5 square grid with only orthogonal lines.  One player plays the three tigers, and the other player plays the twelve oxen.  The board is empty in the beginning.  Players first drop their pieces onto the board, and then are able to move them.  The tigers can capture the oxen by the short leap as in draughts and Alquerque, but the oxen attempt to elude and at the same time hem in the tiger.  Sua Ghin Gnua most resembles the tiger hunt games (or tiger games) such as Bagh-Chal, Rimau-rimau, Main Tapal Empat, Catch the Hare, and Adugo since they all use a 5 x 5 square grid.  But tiger games technically consist of a standard Alquerque board which is a 5 x 5 square grid with several diagonal lines criss-crossing through it which are completely missing in Sua Ghin Gnua.  There are however some variants of Catch the Hare which have missing diagonal lines also.  Another game that resembles Sua Ghin Gnua is from Myanmar called Tiger and Buffaloes which is a hunt game consisting of a 4 x 4 square grid with no diagonal lines.  Myanmar happens to border Thailand geographically so there might be a historical connection between the two games.  Another game from Myanmar is Lay Gwet Kyah that is presumed to be similar to Sua Ghin Gnua.  Sua Ghin Gnua was briefly described by Stewart Culin, in his book "Chess and Playing Cards: Catalogue of Games and Implements for Divination Exhibited by the United States National Museum in Connection with the Department of Archaeology and Paleontology of the University of Pennsylvania at the Cotton States and International Exposition, Atlanta, Georgia 1895" (1898).  It's also briefly mentioned by H.J.R. Murray in his book "A History of Chess" (1913).  It was also described by R.C. Bell, in his book "Board and Table Games from Many Civilizations" (1969).
