I call these ones "Clueleast" because out of 729 cells in the grid, only 2 clues are given and still they have unique solutions. Of course several variant rules are needed (NC AK AN & FNC AK AN repectively) but they're still very neat IMHO.
And they also serve an important usage to me: the sets of rules in a 9x9 grid will both produce 72 solutions. You can find all of them in the solution grids here by taking each of the 9 subgrids and then rotate/reflect it to get 7 others, thus 9*(1+7)=72.
