So today, I will make you create a puzzle if you want to. If you don’t want to, there’s still 2 puzzles to solve if you read on 🙂
First, below all this is a Heyawake(Room and Reason) puzzle. <If you just want to get to the 2nd puzzle and not create it( 😉 ), go to the 2nd paragraph after the bullet points>. If you want to do the whole thing, there’s a guide grid. This guide grid is made up of 3 colors, yellow, blue and white. Now, as you shade in the Heyawake, if the shaded regions correspond to
- White cell – Make it a white Masyu circle.
- Yellow cell – Make it a black Masyu circle.
- Blue cell – Make it a grey Masyu circle.
Once you finish this, it’ll be a Masyu variation with grey circles. I’ve seen Masyus with grey circles on other blogs but my greys behave a bit differently probably. At a grey, the loop has to turn. On one side of the turn, the loop has to turn immediately again. At the other side, the loop cannot turn immediately. To better illustrate this, below is an example with its ONLY solution. You can find that puzzle directly here (Password – BWG).
Anyway, here’s the first puzzle with a separate grid with the guides :
