Basically,Glad I'm not the only one that doesn't understand the tetris puzzles. They make zero fucking sense. If someone can explain I would appreciate it.
you can trace around a single tetris piece in that particular shape to "complete" it. The challenging parts come in as you "combine" two different tetris pieces...as long as the combined piece still contains both origin pieces in its boundaries, then they can be combined in any way, first over second, first under second, first to the left and one block down, etc., as long as they're touching. Figuring out how they combine while managing to keep the symbols in the boundaries is the challenge.
