Yucata' is a game for 1–4 players, any of whom can be AIs or humans. The spaces on the board in this computer version exactly match the ground plan of the Palenque archaeological site. The object is to collect pale stones (blessed by good spirits), while avoiding dark stones (possessed by evil spirits). Each player holds a hand of 7 cards (1–5, and two special move cards). They play a card, then advance their stone around a track as many spaces as the number played, collecting any good or bad stones they pass or finish on. Timing is everything, as you want the good stones, while avoiding the bad. This is reminiscent of the African game of Mancala, but more sophisticated due to the good/bad dichotomy of stones.

Overall, Yucata' is an outstanding rendition of the intriguing and unique ancient game. In addition to a capable AI, the game boasts outstanding graphics, sound effects, and music that adds to the mood. The game also includes well-written rules both in Windows on-line help format, and a separate manual. If you enjoy contemplative mind games in a unique setting, Yucata' is one of the best freeware games you'll ever play. Two thumbs up!
