This is a continuation of the Mahjong game from the same maker, however the real troublesome part is that the actual systems don't change. The only change to this further game is the levels and even there, it isn't immediate. This game offers the same simplistic version with letters, numbers, and colors- as well as not offering any optional map choices, just progression through the maps. But as expected, it's easier to win in the end this way. Not that it makes any difference, I'm pretty sure the tiles are still pretty variant despite the 'simple' mode, but if I were you- I'd play it in the original format.. True Mahjong; only change things for the better, not for difference.
