Strange-Shaped Sunday became estranged-shaped Sunday a while ago when we decided to stop doing it every week. I found myself missing it a little, so here's a Heyawake on a Triangular grid!

Rules: Shade some cells such that no two shaded cells share an edge and any unshaded cell is reachable from any other by crossing cell edges. A number in a region indicates the number of shaded cells in that region. No line of unshaded cells parallel to a cell edge may cross more than one region border.

Tip: I like considering the unshaded connectivity rule both in standard Heyawake and on this grid type as instead being "a diagonal chain of shaded cells must not touch the grid border more than once." Of course, on a triangular grid that isn't strictly true because cells on the border can share corners, but the idea is the same!
