"Chichen Itza 2" by Tergo

This new take on the Chichen Itza layout features over twice the number of tiles, a cool stairway inside, and a sub-basement. At 864 tiles, this is the largest layout yet, at least as far as I remember...  it probably requires version 1.3 for its performance enhancements, to be playable.

Load this layout in Moonlight Mahjong on your iPhone or iPod Touch.

Requires Moonlight Mahjong 1.3 or later.
