There are several games online that are like Queen of the Nile or Cleopatra. I am going to try out the gaming club tonight with $75 of my money and $225 of theirs. They use microgaming software, and those casinos offer several games that are similar:

Thunderstruck and Spring Break are virtually identical. Harvey's, Isis, and Avalon are similar but have some added twists like 20 free games at 6xs pay! Check them out as well. Below is a link to the gaming club offer (in the middle of the page).
