25 tiles from a double-six dominoes set are dealt in 5 columns of 5 tiles each and remaining tiles are set aside to form a reserve. Bottom tile in each column and any of the tiles from reserve can be paired together. When a column gets empty, it can be filled with bottom tile from any other column. The game is won when all tiles are removed from the board.
