Puzzle 28: Mochikoro 2


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.

Puzzle 20: Mochikoro 1


My first attempt at constructing this style of puzzle. Let me know if there are any other styles of puzzle you would like to see.

Rules of Mochikoro

  • There are no 2 x 2 areas of dark cells
  • You can get from any light cell to any other moving only through light cells which are adjacent orthogonally or diagonally.
