The mystical Sphinx may award huge prizes in this fun pokie game - a 5 reel, 20 payline slot machine game. You can't win or lose any real money.

How to play:

To play, first add some virtual cash to your game - just click on the $50 or $100 notes to add $50 or $100. (If you haven't yet registered your game, you'll only be able to add 50 cents a time, so click here to register now!).

Once you've added your cash, click on one of the bet buttons on the top row - you can bet up to a huge $10 a time. The more you bet, the more you can win. You're now ready to play - so click the SPIN button to start your way to fame and fortune. Click on autoplay if you prefer to sit back and watch the game play with itself. You can click on PAYTABLE at any time to see what the symbols will pay.

You can gamble any win to try and increase it - see doubleup help for how it works.

The Eye of Ra wildcard will substitute for all other symbols except scattered Sphinx symbols. Press F5 to play a 5 reel game, or F6 to play a 6 reel game - its that simple!

The Sphinx Feature:

But wait, there's more! If you get two or more scattered Sphinx symbols (these symbols can appear anywhere, they don't have to appear in a row) all other reels will respin. If you then have 3 or more Sphinx symbols, you win 15 FREE GAMES - all pays tripled.
