but this game has gil but it at the mayan temple area.
It sounds like you're talking about "Riddle of the Sphinx."
"Cleopatra: Riddle of the Tomb" is a different game.
As Marian suggested, "The Omega Stone" is the game Omni Creative made after "Riddle of the Sphinx."
Unlike "Riddle of the Sphinx," "The Omega Stone" took place in several areas, including Egypt, Easter Island, Chichen Itza, Stonehenge, etc.
The Chichen Itza area would be Mayan.
