Masyu, a rather easy one. Draw a loop on the grid cells (connecting cell centers) so it passes each circle. When passing a black circle, it must turn there but may not turn at the squares exactly before and after it. When passing a white circle, it may not turn there but must turn at at least one of the squares exactly before and after it.
First anti-symmetrical Masyu I managed to complete (all other anti-symmetrical Masyu I’ve made are ambiguous at one part of the loop T_T ). But then I need to figure out how to make the circles -_- Finally I went through the manual approach; making the black circle and white circle template, then copying them to target cells. The puzzle itself is pretty good IMO.
