Logical Progression is a very unique cube. With only one solution which must be accomplished with serial assembly, it seems at first look that this puzzle will be a trial and error nightmare. However, the puzzle is designed such that scrutiny of the pieces will reveal their positional constraints; therefore the puzzle can be solved by analysis rather than guesswork. More information can be found HERE.
Construction of this puzzle is very good, with an accurate fit. Because of all the dowels, the puzzle pieces are not overly tight, but pushing everything together once it's on the shelf shows the accuracy of the pieces...everything settles together and it displays quite nicely.
