Agent 51

If you are a fan of aliens conspiracy theories, X-Files series, or even detective-style movies, this is a place for you!

The creative Kalamba Games team has come up with the idea to transport their punters back in the 1960s and put them in charge of investigating all manner of unusual goings! 

Besides, the fans of the Book of...genre are going to like the fact that they will play a more balanced version of it, combined with a unique base game K-Loops feature that peaks on every 10th spin!

Theme and Symbols

Agent 51 is a real detective-style online title set into a crowded office, filled with all sorts of accessories, created in a cartoonish manner.

The big blackboard with various sticky notes on it represents the reel set, surrounded by bookshelves, boxes, detective's hat, and coat, while the blinds are slightly opened, allowing the light to peek through the windows barely.

Overall, it is a very detailed scene, with a suitable soundtrack that resembles the sounds of aliens coming and trying to mess up the frequences.

A refreshing fact is that all of the symbols are theme-related, showing five different alien footprints and four variously-colored creatures, while...

...the Agent is both the Wild and Scatter symbol.

You will also come across the accumulation symbol represented by the Polaroid camera and an extra Free Spins symbol represented by an alien ship.

Betting Options and Other Functions

This special agent-themed online title from the Kalamba Games slot list is played across 5 reels and 3 rows while offering 20 ways to win.

It is a high-volatile online game that features an above-average return to player percentage of 96.17%, the hit frequency of 59 (see here), and the max potential win of 5593x your total stake from a single spin.

Before you embark on a secret mission, though, you need to set your bets that range from 5 p/c to £/€50 per spin.

When it comes to the paytable, it starts with the low-paying footprints symbols, paying up to 1x and 3x the stake, while the high-value monsters symbols reward for only 2 in a combo.

The blue and purple ones pay up to 12x the stake, while the highest-paying yellow alien rewards up to 80x the stake, which is the same amount the Wild symbol boasts.

Special Features

To start listing this online game's bonus features, we should first mention the so-called K-Loops, as this one is seen most frequently!

You will notice polaroid photos above the reels showing every symbol of the game. Each time the Polaroid camera appears across the reels, it will snap a photo and accumulate one random symbol.

Besides, if a camera displays an already highlighted symbol, it will increase the symbol's Multiplier by x1!

Every 10th spin will make all of the highlighted symbols above the reels become Expanding symbols that will award some prizes even if they do not land on adjacent reels. 

But, you will need at least two high-value or three low-value symbols across the reels to form an Expanding symbol win!

Now, the whole game revolves around the special agent symbol that performs a dual role – one of substituting for all other symbols and the other of triggering the Free spins feature!

To trigger it, you will need at least 3 of those symbols anywhere across the reels. But, before you start the bonus round and spin an extra eight spins, you will be awarded a randomly chosen Expanding symbol in a real Book of manner!

Besides, every time the Polaroid Camera symbol lands, it will increase the number of chosen symbols as the extra spins play out!

But wait, there's more!

During these bonus spins, you will notice a UFO symbol that acts as an extra Scatter and awards two extra spins whenever it lands across the reels.

Lastly, the devs team also incorporated the HyperBonus option that allows you to purchase the bonus round at any time by choosing three different bonus buy options!

Verdict

Overall, Agent 51 is a decent online slot machine from Kalamba Games' slot portfolio with an exciting theme, beautiful visuals, and a nice pack of features!

Although the maximum potential prize could have been higher, the fact that you can have Expanding symbols on each 10th spin, a Free Spins round, as well as some multipliers to help you create as many winning combos should be enough to attract all types of punters!
