Author/Opus: This is the 277th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place each of the given words into the grid, reading across or down; all words should interconnect, and all words formed in the grid must be from the list. Each given letter must be used by at least one word. Additionally, draw a Masyu loop: a single closed loop passing through each of the “O”s and otherwise using only unused squares. When passing through an “O”, the loop must go straight through and must make a 90 degree turn in at least one of the adjacent squares.
