I bought this YD-638 Sudoku game online (not on Amazon) for my wife's anniversary present after it was reviewed in AAA VIA magazine. She is a savvy geek/addict/sudoku expert and gave up after half an hour. The instructions are "typical of a foreign product" - poor translation from Chinese to multi-page horrible English. It's a piece of junk. I sent an email for a refund. There must be an acceptable device somewhere, any information on a good model to buy would be greatly appreciated.
