Rubido is a chinese checkers clone, it's also known as Solitaire in certain countries. You have a board filled with pegs where you jump over another peg to an empty place and by this you remove the peg you jumped over. Depending on the difficulty diagonal movement is allowed or not and you either have to end in the middle or not.
