Puzzle 15: Masyu

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.

Puzzle 15: Masyu

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.

Puzzle 6: Antisymmetric Light Bulbs

Akari Put some light bulbs on the cells of the grid. Light bulbs illuminate all squares in the four orthogonal directions (up, down, left, right), up until reaching an edge of the grid or a black square. Illuminate all squares, but no light bulb may illuminate another light bulb. A number on a black square determines the number of light bulbs orthogonally adjacent to it.

Akari

We interrupt the IMO 2012 series for this post and the next post.

Yay for puzzles. Guess I’m back at “logicsmithing”.

This one is a pretty easy Akari. However, the aesthetic part of this puzzle is rather high by my standards. Opposing givens add up to 3, just like some Slitherlink I’ve seen…

*went browsing for like 30 minutes*

Oh hey I can’t find that puzzle. Whatever; it means I can make it some time soon and claim it as the only one in the last [insert a small time interval (less than a year)] 😛

Whatever. Akari, 10×10. Would go to an easy or something. Did I repeat myself?
