About Hiroba, from BoardGameGeek:

Win the game of Hiroba by shrewdly placing your numbered pebbles so you can take control of the most gardens. As in Sudoku, you must never have two pebbles of identical value in the same garden, row or column. Beat your opponents by thinking strategically, but don't neglect the highly coveted Koi, which can earn you precious points. Will you be able to retain control and stay Zen in the face of your opponents? -description from the publisher
