Well, that is a very rare puzzle.
Earlier this year, someone called Smaz was offering chinese made copies of the original 1980's Rubik domino cube on Ebay. Smaz was charging only $15 USD for each one.
I brought one from Smaz on Ebay. It is really fun to solve. You can use Meep's PLL list but the PLL regonisition is much harder. At most it should take at most three PLL's to solve the top layer, with an average of two PLL's.
