As someone who has enjoyed playing Mah Jong for nearly 20 years this game was a bit disappointing. There wasn't much to make it stand out in regards to Mah Jong games on other platforms. The graphics were tiny making it hard to see even for a person with perfect eyesight. It is an ok rental if you really love the game but definitely nothing I would purchase or even rent again for that matter.
I enjoyed the assorted mah jong puzzles and had a great time playing thru this game . . . until I hit the wall on the Swaptastic puzzle. The in-game help provided no assistance; there is no info for this game available at gamefaqs; and nor did I find info by googling the game title.
I'm not sure if the guide that comes with the game offers puzzle-specific instructions; if so, I would buy this game without hesitation and would give it a higher rating.
