First, I would like to thank Sandy for giving us a chance to display our collections.
Rubik's cube was "hands down" the most popular brain-teaser puzzle in the world, like you can witness everyone jumped on the band-wagon and followed suit with a slew of variants, but the reference remains the Rubik's cube.
I started collecting cubes and brainteaser puzzle in 1996. But more seriously in 1999. At first, I thought of collecting only original Rubik puzzles, ...but slowly I am trying to collect a couple of variant mostly in shape, since i do not collect sticker variants. I have not yet tried to modify existing puzzles, but would like to in the near future. This is part of my collection.
