Beginner explorers have a choice between three different game modes in Kingdom of the Dead. You can enhance your chances of getting scatters by 50% by clicking the Ante Bet, which raises your bet from 0.10 to 250 on individual paid game rounds. Finally, you can pay 120 times your stake for 10 free spins. Kingdom of the Dead operates on a highly unpredictable mathematical model, but both of these methods have a maximum return to player value of 96.07%.
There are 10 fixed bet lines across the game's grid of 5 reels and 3 rows of symbols. The lowest payouts occur in the form of 3–5 wins, and the corresponding card ranks are 10–A. Various high-paying symbols, such as a scarab, Anubis, Pharaoh, and explorer, award prizes for combinations of two to five of a kind. If you get five of a kind on a winning line, you'll win between 10 and 15 times your wager with royals and between 75 and 500 times your stake with premiums.
Kingdom of the Dead follows custom by making the book symbol both wild and scatter. The book icon acts as a wildcard, replacing standard game icons where appropriate. Three, four, or five of these symbols anywhere on the reels not only activate the free spins bonus but also pay out 2x, 20x, or 200x the wager. Players receive 10 free spins in the free spins feature and can choose between two different games:
Fixed Mystery Symbol: At the beginning of the round, a random pay symbol is chosen to be the special expanding symbol.
The special expanding symbol is a pay symbol that is chosen at random for each free spin.
After standard winnings have been given out during free spins, if the expanding special symbol can create a win, it will expand to cover the entire reel. Expanded symbols pay over all active lines and can appear in any place inside the active area. Free games in the Mystery mode are multiplied by 10 if 3 or more books appear as scatters during the round. The number of subsequent triggering events is unlimited.
