The Mystical Egypt slot machine is a fairly simple game to play. Change the amount you bet. Per spin, you can wager anywhere from.10 to 100 coins. In a carousel box above the reels, a mystery symbol chosen at random is included with each base game spin. You can choose from any of the regular pay symbols, and if you land enough of the chosen symbol to win, it will expand. In practice, this indicates three or more matching royal symbols or at least two matching premium symbols.
It doesn't matter where the Mystery Symbols land; as long as you have enough to form a winning combination, they will expand to cover the entire reel. This is typical of the book slot mechanic in the bonus round, but you also get it in this game when you play the base game.
In most games, the scatter or wild is the Book, but in this one, it's the Egyptian Queen. However, it continues to substitute for all regular symbols to assist you in forming winning combinations, and it pays up to 200 times your stake for 5 paylines. Keep in mind that expanded symbols cannot be replaced by the wild.
The bonus round is triggered by landing at least three scatters or wilds. No matter how many scatters you land, you will get 10 free spins. In most bonus rounds, you only get one special symbol to choose from, but in Mysterious Egypt, you get two. Similar to the base game, these special symbols will expand, resulting in larger payouts when both symbols expand simultaneously.
If you get three or more scatters anywhere on the same free spin, you can retrigger the free spins round. This grants you ten additional spins, but the selected special symbols remain unchanged. There is no restriction to the number of twists you can end up in such a state.
