Hi Non-Twisty Puzzles fans,
Osdas 4x4 is a sliding-piece puzzle without a frame. Regular sliding piece puzzle, like the classic famous 15 puzzle, have pieces sliding in a frame, such that they do not fall out. The Boomdas puzzle is a 3x3 sliding puzzle from Japan has no frame, while the pieces still hold together. Boomdas has a cubic sibling called Muto Cube. More info here, here and here. However, one can easily cheat with Boomdas (and Moto Cube) by sliding them apart and putting them back together.
Osdas 4x4 is a frame-less sliding puzzle similar to Boomdas, but with links between the pieces that prevent the puzzle from coming apart. No cheating with this one!
This puzzle has the interesting property that it is possible to swap some adjacent pieces, e.g. 9 and 10, which is not possible with the classic 15-puzzle.
