Newfound Square-N enthusiast who realized that this puzzle can do a lot of cool things
I only recently learned how to speedsolve Square-1, so I figured this would be the logical next step. I find the solution pretty simple: I just pair up the pointy corner pieces until they're like regular corners, then solve it like a regular Square-1. The turning on this is pretty smooth even out of the box, and although it's pretty dry-feeling I haven't lubed it yet so far. The slice isn't magnetic, which I don't mind. I'm not a super huge fan of how there's magnets in every single top and bottom layer piece, though, because you can just feel that cliclicliclicliclick with every turn and it sort of bothers me. However, Square-2 isn't a super competitive market so there aren't many other options you can go to.
Some fun things you can do with it:
-Literally any bandage mod you want: Since this cube has smaller "piece increments" than a Square-1, you can make a lot of fun bandage challenges. I taped every other piece together in the layers to make what I call a "Square-6" because it has 6 pieces per layer. I haven't been able to solve that particular challenge yet, but I peeled the tape off and invented a bunch of other cool things. You can also make a Square-0 where you bandage each full 60-degree corner with its adjacent edge (although this can be done on a regular Sq-1 too) or some sort of "Square-0 dino cube" where you stick together a 30-degree corner wedge with another edge piece and its opposing corner wedge, basically making it all edges.
-Flip the color scheme: You can intentionally put the corners together incorrectly so it seems like the top and bottom are flipped. For example, instead of making a corner with yellow on top, red on the left, and green on the right (how it would be normally) I can pair the corner wedges so that the red is on the right and green on the left. I do this with every corner in the cube and then flip the middle layer like how you can do it on a normal Square-1 so that two opposing sides are switched. The end result is a solved cube with the color scheme flipped.
-Anything else you can think of!
At first I thought this was going to be lame because it's just a Square-1 with spicy corners, but now I realize that there's no limit to what you can imagine with this cube!!!
