Many traditional board games are played blind, e.g. Chess (called "Blind Chess"), Checkers ("Blind Checkers"), Nine Men's Morris and Go ("Blind Go"). Mancala games can also be played by the blind or, to make the challenge more difficult, by a blindfolded person. In Toguz Kumalak, a traditional Kazakh mancala game played all over Central Asia, there are regular championships for the blind and clubs where blind people daily practice this game. In tournaments they use special boards and notation sheets. The current Toguz Kumalak World Champion of the Blind is M. Kurmanbetov.
