As you’ll see, I was too lazy in explaining the puzzle types. From Berkeley Mini Math Tournament, a middle school math contest run by UC Berkeley undergrads.
It’s been a while, Masyu.
EDIT: Due to multiple solutions, an additional circle has been added. No good reason for the mess up.
An easy Masyu inspired by music..
Clearly this is a variant of Masyu. Go figure.
There’s some (accidental) symmetry going on. Figuring out a representation took long enough that less interest went into the puzzle than it deserved.
Masyu. There’s obvious symmetry going on, but I’m decently happy with the logic as well. If-then logic isn’t necessary, though the puzzle is significantly easier if it’s used. Nice to make another puzzle after a break.
Masyu. Still not making many (any); thankfully I have a backlog of made puzzles.
EDIT: This one should be new 😛
