Very Solid Japanese Mahjong! – Mahjong Demon XL - Japanese Mahjong Review

While I'm far from a Mahjong expert, the AI sure seems competent and can actually score some pretty specialized hands. The interface is very intuitive and I love how it uses (or at least gives the option for) the Western tile set. It also keeps decent statistics. Some of the documentation suffers from a bit of poor translation but it's still fairly followable.
