This is a decent single-player mahjong solitaire game, but it's not worth $9.99 (the current price at this moment).
I bought it on sale in December 2010 for just $2.49 as the Games for Windows deal of the week and I thought it was worth that price. It's probably easy enough to find a game like this on the web to play for free but this one comes with 200 potential achievement points.
There are 3 modes of play: a story mode called "ancient tales", "motion - mahjong with an action twist", and "classic infinity - play hundreds of layouts or create your own".
The "ancient tales" story mode consists of 5 sets of 9 tile layouts with short forgettable but well drawn and narrated stories between each layout. Playing mahjong solitaire amounts to matching open tiles to remove them from the field of play, revealing more tiles. The goal in story mode is to match the two special yin-and-yang tiles buried below. You are timed and get bonus points for tiles that remain.
In "Motion" mode you have to play fast or your game is over. The goal is to clear all the tiles from the field of play by matching them with nearby tiles or with other tiles going by on a conveyor. The conveyor also has special tiles which can help you. All the tiles must be removed from the field of play before the tiles on the conveyor reach a dragon, or the game is over. If you clear all the tiles you move on to the next layout and your score goes up.
The goal in classic mode is simply to remove all the tiles from the field of play. You can play one of the layouts provided, or make your own. There doesn't appear to be a way to share the layouts you create.
The game provides leaderboards for "ancient tales" and "motion". When I first played this game there were just 852 people on the first leaderboard and only 165 on the second which gives you an idea of how many people had bought this game before it went on sale as the deal of the week. The leaderboard interface is seriously lacking with only minimal control -- you can select a leaderboard and go forward and backward 10 at a time, that's it.
Another example of overlooked functionality is that story mode can't be replayed easily. Once you finish story mode you can only play individual levels one at a time. There's no way to start over normally without finding your save file and renaming/deleting it outside the game.
Sound isn't bad. The music would probably get repetitive after a while but it can be turned off. Sounds effects are OK and can also be turned off separately.
The game has help screens for each mode which get you up to speed quickly and easily.
I don't have a high-end graphics card and was able to play story and infinity modes without any major problems although the tile matching animations were a bit slow. Disappointingly, motion mode was so slow that it was virtually unplayable. Why does a simple tile matching game require an advanced graphics card?
Mahjong Wisdom is a basic flawed single-player mahjong solitaire game. If you don't mind wasting some money to immerse yourself in clicking matching tiles and pick up a few achievement points in the bargain, it's not too bad. I just don't think it's worth more than $2.50.
Update: It's well over 3 years later and now I have a better graphics card and, amazingly, Motion Mode is still too slow to play properly. The matching animations block my view and take forever. This means that 4 achievements are unachievable for me even with a PC the plays Skyrim on High/Ultra settings. It's quite astonishing really. It's so laggy that tiles have to be clicked multiple times before the input is accepted. I can't imagine what was going on when they wrote this game. Knocking my rating down to 2. And I'm being charitable. I would delete the game but I'm note sure if I'd ever be able to download it again from Games for Windows Live. Besides, I'm curious to see how this game runs on the supercomputers I expect we will all own in another 3 years.
