River of Riches is a 5-reel video slot that takes you to a pharaoh’s tomb for immense riches. This slot was designed by Rabcat, a leading producer of casino game applications, and released on the Microgaming’s Quickfire platform. Anyway, the slot differs from many other solutions of Microgaming due to its rich 3D graphics and unusual interface. The reels seem to be made of stone blocks and placed inside a sanded tomb or temple. UI elements such as Lines, Bet, Spin button and others, are stylized as time-eaten boulders positioned in front of the reels. Win animations are impressive, too.

There are two buttons for controlling a bet amount. These enable you to change the number of paylines between 1 and 25, and select a bet per line ($0.01 to $2) so the minimum and maximum stakes are $0.25 and $50 per spin.

The symbol set comprises four playing cards 10 to King and four themed symbols including Pyramids (pay x250 for five of a kind), Black Scarab (x250), Ankh (x500) and Pharaoh’s Mask (x1000). If you play at the maximum bet and get five masks on an active line, you win $2000, which is the second largest prize in the game.

Bonus features

Isis is a scatter that triggers 10 free spins, should three or more occur in any position. Five Isis symbols award the top jackpot worth $2500 at max.

The slot boasts of two wild symbols, a regular wild and a fixed wild, both substituting for other pics. The regular wild is represented by Explorer and appears in all gaming modes. Sad enough that the wild cannot create its own combinations; however, its acting as a substitute can bring you some good wins.

The fixed wild is depicted by a flaming fire word ‘WILD’ and it becomes active in free spins only. Upon gaining entry into a free spin feature, you are awarded one fixed wild on the second reel and up to 3 fixed wilds on the fourth reel. These wilds stay stuck on their initial positions until the end of free spins. There are chances that new fixed wilds land as the feature continues, so you can end up free spins with lots of wilds visible on the screen.

An optional Gamble feature is a simple ‘Guess a Card Color’ game where you can double your wins up to five times in a row.
