In 4 Corners of Rome, the reels are set against a blurry picture of white ancient grandiose buildings. We can see some blue water running between the buildings, as well as some green vegetation.

Two marble pillars frame the reels, and to the left of them are the Lock and Load multiplier and the Bonus Buy button, depicted by a golden eagle. The reels have a light brown background, and the positions in the four corners are highlighted since the symbols landing there can activate the Lock and Load feature.

Prior to hitting the reels, the landscape is pretty static, with only the Bonus Buy eagle spreading its wings occasionally. With male and female voices chanting, the music has a dreamy, mystical feel.

The player needs to land at least three of the same symbols on any of the 40 paylines to win. The first reel to the left must be the starting point for a winning line. Mobile, desktop, and notepad versions of 4 Corners of Rome are available.

Spades, diamonds, clubs, and hearts are the lower-paying symbols in ancient Rome. For a combination of 3, they pay between 0.1X-0.3X, and for a combination of 5, they pay between 0.3X-0.8X. More valuable symbols include a scroll of papyrus, a jar of purple grapes, and a Roman warrior helmet.

For a full combination of 5, they pay 1X-2.5X the bet. Wild symbols substitute for all other symbols. For a combination of 5, it pays the same amount as the Galea with 2.5X the bet. You can't substitute the wild symbol for the scatter symbol, which activates the free spins and boosts the Lock and Load multiplier. In the free spins, a multiplier symbol can also appear.

You can win up to 6300X the bet.

The features are Wild Symbol, Scatter Symbol, Lock and Load Multiplier, Lock and Load, Free Spins, Multiplier Symbol, and Bonus Buy.

The Wild Symbol is depicted by the letter W. It substitutes all symbols except the Multiplier Symbol, which only appears in the free spins, and the Scatter Symbol.

The Scatter Symbol is a golden eagle spreading its wings and looking to the distance. Below the bird is the text “bonus.” The Scatter Symbol appears on reels 2, 3, and 4. You need to land 3 symbols to activate the free spins, and 2 symbols add +1 to the Multiplier Meter.

The Lock and Load Multiplier sits to the left of the reels. It starts at X1, and can go up to X5. It is used to multiply the next win in the Lock and Load feature. You increase the number in the Multiplier by 1 every time 2 scatter symbols hit the reels.

The Multiplier is reset to X1 after the Lock and Load feature has been activated and used. The Multiplier stays on the same value during all free spins and resets when the feature is over.

The Lock and Load is a pretty innovative feature the guys at Northern Lights Gaming have come up with. The four corners of the slot, in other words, the top and bottom position of reels 1 and 5, stand out, giving the symbol that lands there some extra shine.

The Lock and Load is activated whenever two of the same symbols land diagonally on the opposite corner (upper left and bottom right, or bottom left and upper right). All 5 symbols on the locking line switch to the same symbols that activated the feature, and they’re being locked on their positions while the reels spin again.

If any of the new symbols takes part in a winning line, it will be locked to its position with the other winning symbols while the reels spin again. This goes on until no new win is being made and the feature is over.

If both locking lines are being activated, the symbol on the intersection of the two lines (the middle position of the slot) is transformed into a wild symbol. If there’s a symbol on a locking line that takes part of a win in another way, it is also transformed into a wild symbol.

When the feature ends, the total sum of the present winning lines is multiplied by the Lock and Load Multiplier. All free spins are guaranteed to trigger the Lock and Load feature.
