The first completed puzzle is the biggest breakthrough. Before solving it, the challenge may seem almost impossible.Trust us—once you complete the first one, everything will start to make much more sense. It takes some patience at the beginning, but after that, you won't want to put it down.

Start by understanding how the pieces should fit together in theory.The easiest way is to begin with the piece that has no holes at all (256). It can only fit into a piece that has one completely open row. If a piece has even a single filled section in that row, the 256 piece won't fit because there isn't enough space.Here's an example to illustrate the idea:This approach is especially helpful for the first challenge, as it allows you to understand the orientation of the pieces and determine which colored piece fits inside another.

Once you've figured out how the pieces should fit together in theory, it's time for practical experimentation.At this point, there aren't many universal hints we can give—there are 68 different challenges, and even we haven't completed all of them yet! This puzzle will keep you busy for a long time.One general tip: piece 256 cannot be added after the other pieces, because it has no openings.That means 256 is almost always one of the first pieces to be placed. You'll either:place it over another piece (so the other piece passes through the opening of 256 and supports it), orslide it into another piece so that 256 already sits horizontally inside it, occupying its internal space.Once the slots become only one cube wide, you'll typically need to insert one piece of each color alternately, one by one.That's it—good luck!This puzzle is all about trying different combinations and discovering the correct position for each piece. Figuring out where each piece belongs is already half the battle. Learning how to insert it is the more technical part.There are additional tricks, but many of them are specific to individual challenges, so it's impossible to describe them all here.We'll gradually add solution videos for different challenges to demonstrate various techniques and approaches.We encourage you to solve the challenges on your own first. But if you get stuck, try watching only a small part of a solution video at a time. That way you'll get just enough guidance to keep making progress while still experiencing the satisfaction of solving the rest yourself.
