Here is a Mochikoro. Note that there is one clue on each row, and one clue on each column, and the clues are the numbers 1 to 10, each occurring once. Note also, that there is 180 degree symmetry, and that the symmetrical pairs are 1-6, 2-7, 3-8, 4-9 and 5-10. Thought that was interesting. That's all.
