# Puzzle No. 425 : Tapa [Diagonal Neighbors]

I thought I’ll add another practice puzzle for the Tapa Variations Contest coming up this weekend. This is a variant I thought up and there’s 2 other instances on this blog that Serkan has linked to in the forum. This particular puzzle isn’t especially tricky but uses the Diagonal rule nicely I think.

Rated – Medium.

Enjoy!
