Flummox vs Tangramthrum

Flummox is a puzzle game about flipping shapes. Each puzzle gives you a few polyomino pieces and a goal for arranging them. Flip a piece over one of its edges and it tumbles across the board (as long as there is room for it to land!). Get every piece where it belongs and the puzzle is solved. That is the entire rule set. The difficulty is in the pieces getting in each other's way: the obvious first move is usually the one that strands you six moves later.
