Logic puzzles #29-32 - EnsembLe

 EnsembLe

These are some old puzzles of mine. I decided to attempt setting a puzzle genre I had never set before (sashigane). I ended up making four of those, with a little progression in them :p

Rules and link

Divide the grid into regions of orthogonally connected cells. Each region must be an L shape with a width of one cell. Arrows must lie at one end of an L and point toward the bend. Circles must lie at the bend of an L, and if one contains a number, the L it’s inside must contain the indicated amount of cells.
