I have just returned from the Fortune Town IT Mall in Bangkok.
(Shop name is "109" and it is placed at 3P41 on the 3rd floor).
Sadly, they told me they had ran out of stock and had no puzzles at all.
I got the information from another forum (I believe Anders gave the tip).
Apart from that and some cheap 3x3x3 variations at the Thai outlet
of Toys R Us, there was nothing else I could find. I would feel disappointed,
but I will be visiting soon two huge Toy Fairs in other countries,
so I am sure I will find interesting stuff there and will keep you posted here.
