In Stakelogic's The Secret of Machu Picchu, a slot machine set in the Peruvian Andes, players enjoy an up-close encounter with the world-famous Inca citadel. Perched on a rocky peak almost 2,000 metres above sea level, the fort dates back to the 15th century. The player assumes the role of an explorer and adventurer in this game. This historical site is being pursued by a white man who is attempting to get money. He can rely on a grid that grows by one row for each cascade win, up to a maximum of seven rows. Another feature is a wild llama, which, when it emerges even when a win is not yet in progress, will eliminate all symbols except the most valued ones.
From a bird's-eye view, we can see Machu Picchu from a little distance. The symbols in the game obscure most of the ancient city, but every spin reveals more structures as the symbols fall from the sky and disappear. There are large, ornamented stone pillars on the side of the reels. With each cascade, the reels expand by one, allowing the screen to display the full grid. If you start on the left-most reel and manage to line up at least three identical symbols anywhere on the neighbouring reels, you win.
The four blue, green, purple, and orange geometric shapes represent the lower-paying symbols in the mountains. With a payout of 30 times the wager for a 6-of-a-kind victory, they are all identical. The circles in blue, green, purple, and red represent the medium-paying symbols. With them, a winning hand of six of a kind pays out anywhere from 0.66X to 0.75X the wager. Adventurer, compass, petrol light and map are the highest paid symbols. You can earn 1.5X to 5X your wager when you make a winning combination of 6 symbols using these symbols. Except for the Scatter, Multiplier, Sun Gate, and Sun God symbols—which only show up during Free Spins—the Wild Symbol can replace all other symbols mentioned.
