Rook

Look! The ants are spiky in this Ant Mill (Triangular)! I really like this grid + genre combo. There are some funny interactions, so I've included a GAPP 101 at the end of this post if you get stuck!

Rules: Shade some dominoes of cells. No two dominoes may share an edge, but each domino must touch exactly two others by the corners such that all dominoes form a single loop. Cells separated by a square must both be shaded or both be unshaded. Cells separated by an X must not.

GAPP 101: Only two dominoes can meet at any vertex! If three dominoes met at a vertex, all three dominoes would be adjacent to two others, and the loop would be closed!
