I am looking for a Four Winds May Jong for my tablet.
This particular version is not available for tablets, but you can install a similar one that has almost the same name for iOS devices. The developers are still in the business and it appears the game is available as well.
You can use the following website to see what the developer has to offer: http://www.tomtomlabs.com/apps.html
As for the Four Winds Mah Jong game, this is only for Windows PCs as stated on the official website: http://www.4windsmj.com/downloads01.htm
For both computer and tablet too. I suppose it is the truth.
