Traditional games:

Traditional games are an integral part of a community's culture and heritage. They are often played using simple materials and are passed down from one generation to another. These games have historical significance and are played for fun, entertainment, and sometimes even to develop physical skills.

Examples of traditional games:

a) Kabaddi:
- Kabaddi is a traditional Indian sport that is played between two teams of seven players each.
- The objective of the game is for one player, known as the "raider," to cross into the opposing team's half and tag as many defenders as possible without being caught.
- Kabaddi requires strength, agility, and quick thinking.

b) Gilli-Danda:
- Gilli-Danda is a traditional game played in India, Pakistan, and other South Asian countries.
- It involves two wooden sticks - the gilli (a small wooden piece) and the danda (a larger stick).
- The objective of the game is to hit the gilli with the danda and score points by hitting certain targets or covering a distance.
- Gilli-Danda requires hand-eye coordination, precision, and strategic thinking.

c) Polo:
- Polo is a sport that originated in ancient Persia and is now played in various parts of the world.
- The game is played on horseback, with two teams trying to score goals by hitting a small ball with a long-handled mallet.
- Polo requires skilled horsemanship, coordination, and teamwork.
- While it is a traditional game, it is not considered a traditional game in the context of this question.

d) Marbles:
- Marbles is a traditional game played by children all over the world.
- The game involves shooting marbles, small colored balls, at other marbles in an attempt to knock them out of a designated playing area.

In conclusion, the game that is not considered a traditional game in this context is Polo. While it is a traditional sport, it is not commonly played as a traditional game in the same way as Kabaddi, Gilli-Danda, and Marbles. These three games have deep cultural roots and are played by children and adults alike.
