Cool list!
I'll throw in one I made for myself and never really showed to anyone. It's a clone of Unblock Me/Rush Hour, but with no ads and undo+redo support. It's only a website since I don't want to bother with app stores (I just save the page to my home screen).

The puzzle variety isn't great, my generation method sorta sucks. I had started to build an exhaustive generator after reading Michael Fogleman's article[1] on it, but haven't finished.
