I’m a big fan of the “dipper x” type of thing. I think it’s the best option out there today. I’ve seen it done by a lot of different people, and it’s always pretty unique. It’s not just a matter of how the dipper is placed, but the whole idea of it.
The best part of the dipper is the fact that it is a very unique way of doing a puzzle game (as opposed to a puzzle puzzle game). It’s all about finding the right placement of several dippers, and then completing the puzzle which is usually presented as a single block of the same color (red). So the fact that its a game where you have to move multiple dippers in a random fashion is pretty unique.
