The "riddles" are trivia questions regarding ancient Egypt. You can either answer them outright (by clicking on the sequence of letters within a word search like grid - but duplicate letters may not be accepted) or can have the letters in the answer revealed one by one as you progress through a level. For those who don't like Match 3 games that don't allow you to continue while the tiles are falling, you will hate this. Not only can you not continue play, but the board moves incredibly slowly.
Although the story line for this game is intriguing, the graphics quality is very poor, making the objects hard to locate. The hidden object screens also "wobble" as you move your mouse, which makes it even more difficult to focus. I like a challenge to my observation skills, not my eyesight! The mini games you play to earn more hints are silly - mousetracking to make clay pots, coloring in paintings, and dressing up dolls.
