Head to a jungle kingdom
The back story here is that the Ivory Citadel is a temple in a jungle kingdom ruled by animals that no human has dared to visit. With the dense jungle and a mighty temple in the background, you’ll see A to J royals as well as 3 more lucrative animal head statue symbols. The logo is the best standard symbol. Land 5 on a payline for a payout of 20 times your stake. There’s also a wild.
Spicing up the base game action are special mystery symbols. All examples of these ? symbols that land on the same spin morph into the same matching symbol. A payout consideration then follows with the transformed symbols in play. Any standard symbol or wild can be the transforming symbol. This is simply known as the Mystery Symbols feature.
Free spins with mystery symbols
The main feature is the Free Spins feature. It’s triggered in the usual manner by landing 3, 4 or 5 scatters on the same spin. Your reward is 8, 10 or 12 free spins complete with a couple of very tasty extras. When a ? lands, it does the same transformations as in the base game. A mystery symbol will be in play in that positions for each of your remaining free spins.
Sticky wild reels
Things improve still further if you manage to get reel full of sticky mystery symbols. They will then magically turn wild and will stay wild for any free spins you have left.
Simple, medium volatility
Just For The Win has created a fine-looking slot in Ivory Citadel. The visuals are terrific. There’s some decent gameplay on offer too thanks to the mystery symbols. That’s certainly the case in the Free Spins feature where landing mystery symbols early in the proceedings can deliver some top action – up to 1,968.8 x stake.
The variance here is in the medium range. We’ve seen more exotic jungle treks than Ivory Citadel – such as Gonzo’s Quest by NetEnt. This is a solid performer though and worth investigating.
