On first appearance Isis seems to be the usual ancient Egypt themed video slot game from the online casino software developer Microgaming. It is unique because it is available in three different formats for three different purposes. All three avatars of Isis can be played at Microgaming online casinos like All Slots, Platinum Play and Spin Palace.

Isis was originally released a 25 payline video slot game. It was an ode to Isis, the Egyptian goddess of motherhood and fertility, also portrayed as a bird. The introductory video clip and the symbols on the reels are rich in Egyptian mythology. Isis is the wild symbol. It doubles payouts and offers a fixed jackpot of 10,000 coins. The scatter symbol is Isis her bird form. The video slot offers up to 30 free spins with payouts multiplied six times. Another feature is the Microgaming gamble game.

Progressive jackpot players at Microgaming online casinos were overjoyed when a version of Isis was linked to the four-tier Mega Moolah network. In this avatar the slot game is known as Mega Moolah Isis. Because of the progressive jackpot Mega Moolah Isis cannot be played in the free play mode. The progressive jackpot comes into play through a randomly triggered bonus round. The four progressive jackpots are represented by different colors on a wheel. After the wheel is spun it comes to rest with the pointer indicating one of the colors. You win the jackpot associated with that color. The Mega progressive jackpot resets at 1,000,000 credits, the Major progressive jackpot resets at 10,000 credits, the Minor progressive jackpot resets at 100 credits and the Mini progressive jackpot resets at 10.

Isis joined the select list of multi player slots at Microgaming online casinos. Multi Player Isis has some additional features as well such as 40 paylines and stacked wild symbols. Multi Player Isis is played in a virtual slots room in which six players can participate at a time. Though each player wagers independently, you can see the screen of the other players. Multi Player Isis allows you to chat with the players in the same virtual slots room. Whenever you get two or more scatter symbols on the reels a Free Spins multiplier is awarded to you. If any player hits the Isis bird symbol simultaneously on reels 1 and 5, 12 free spins are awarded that are common to all participating players. The payouts for each player will however be multiplied by their individual accumulated multipliers.
