The Ivory Citadel is a high volatility slot, featuring 5 reels, 20 paylines, and accepting bets in the range 0.10 – £100 per spin. The low-value symbols are the standard Royals. The better-paying ones are a snake, tiger, and buffalo. The game logo is the best payer that gives you 40x your stake for 5 OAK. The wild replaces all symbols bar the Free Spins and the Mystery symbols. The elephant is the scatter that triggers the free spins.
All instances of a Mystery symbol reveal a matching symbol thus increasing your chance to score a win. The Mystery symbol can reveal any symbol except for the free spins symbol.
Land 3, 4 or 5 elephant symbols to get 8, 10 or 12 free spins, respectively. If the Mystery symbol appears during the free spins round, it becomes sticky. If you cover a whole reel with Mystery symbols, they transform into wilds and remain locked in place for the duration of the free spins round.
It looks like JFTW tried to come up with an entertaining slot, but ended up with a middle-of-the-road title that is not as nearly superb as the intense, graphically stunning, feature-rich slots of the competition. That being said, the Ivory Citadel can accommodate the needs of a casual player, but it has slim chances of attracting seasoned ones.
