The Jackpot symbol is the Aztec Treasure logo. The current jackpot amount can be seen above the reel, and the reel can only be won when the maximum bet is won. After each rotation, you can choose to keep one or two reels and then rotate them again. This can come in handy if you think that holding the reel can bring you the next spin victory.
Whenever there is a symbol with a gemstone on the reel, the Aztec chief will come from the side of the reel, throw a javelin at it and knock it down. You need to collect 3 gems: blue, red and yellow. Once you collect it, you will trigger a bonus round and you will be taken to another screen. Here you need to put the gems in three places and you will receive the prize.
