SUDOKINO(pronounced sue-do-kee-no) is a reduced version of the well known number puzzle Sudoku. While the latter is generally played on a 9 x 9 grid, SUDOKINO employs a 6 x 6 grid, divided into 6 regions, each consisting of 3 x 2 cells.
Besides, in SUDOKINO, colours, rather than numerals, are used.
There is only one rule: starting from a given situation, the empty cells must be covered with the coloured tiles in such a way that each horizontal row, vertical column, or region (the 3 x 2 subgrids bounded by rubber), will contain only one instance of each colour.
The 36 wooden tiles are printed on both sides: the squared side is used for given positions, the full colour side is used to complete the grid. Here we present 3 levels of problems: easy, medium and difficult. Solutions are given for all of them.
