love it, i like chess puzzles but have never been able to play the ones in the newspaper or in books. So its good to undo, and see things visually (I know chess fans do it all mentally though)

Didn't win it, got 2 greens and one orange at best!

Chess.com and lichess both have puzzles, the latter are free and you can play through them like this, sort of, except you only make moves for one side.
