Hello world! #1, #151, #201, #251 Numberlinks

Hi everyone! I've been making a logic puzzle a day for the past 8 months. They used to live on a private spreadsheet, and were shared among friends. But due to the support of some amazing people (Pavel at http://www.pavelspuzzles.com/site/ and calica at https://puzzles.covering.space/), I've decided to start posting these online!

My roommate IHNN would arrive later. Tim and Dan were both on the USA B team like me, so I made sure to greet them well. People were practicing castle walls, and I heard tluo considering buying a GMPuzzles subscription for more math path pract

Parity and Simple Loops (and 5 puzzles)

Image
Before posting the simple loops, I would like to give an introduction to parity, which will be useful for tougher puzzles. If we consider the grid as a checkerboard, any loop segment will alternate between gray and white cells. Here are the simple loop puzzles as promised. Most won't require parity deductions. #227 https://puzz.link/p?simpleloop/9/8/0030h20g3486000 #13 https://puzz.link/p?simpleloop/8/8/240g00200gs00 #63 https://puzz.link/p?simpleloop/13/12/10h0002oc0002000g8c00000g5002100 #120 https://puzz.link/p?simpleloop/21/10/g0g03o80004kggf08000o20203iph0g4a0220109g3 #257 https://puzz.link/p?simpleloop/12/12/1g004g04000000002g000002000h0
