The cobra is the wild symbol, it will substitute for all of the other symbols, except for the scatter and bonus symbols, to help and form winning combinations. The wild can only land on reels 2, 3 and 4, but when it does, it will expand to fill the entire reel.
The desert princess is the scatter symbol and the key to the free spins.
If you land three or more scatter symbols anywhere on the reels you will be rewarded with fifteen free spins during which all payouts are doubled. Best of all, the free spins can be retriggered indefinitely.
If you land three or more of the bonus symbols along an active payline from left to right then the Oasis Bonus game is triggered. The first stage of the game is set at the desert oasis and you will be asked to pick from seven different treasure chests. You will receive the same number of picks as there were triggering symbols. In addition to cash prizes, the chests may contain a map to a second bonus stage. If you find the map then you can then choose between visiting a secret tent or a hidden cave where you can pick from plates of fruit or urns respectively for more cash prizes.
