THE STORY

Open the door to a dim room that seems to the office of the secret agent 51. The location is like that in the X-Files TV series and the storyline has similarities with its plot. Agent 51 is the main character in this story. He investigates alien invasions and collects pieces of evidence of this unusual arrival. You are offered an exclusive opportunity to become a member of the team and search for evidence on the reels. Will you dare to open the door to this paranormal world?

THE PAYTABLE EXPLAINED

The machine has a quite common configuration with 5 reels and 3 symbol rows and 20 paylines. The uniqueness is in the mechanics. You take pictures of evidence for 10 spins. After the tenth rotation, the grid explodes with special bonuses and rewards a big payout. Place a bet of anywhere between 0.5 and 50 credits and begin the investigation.

Special Symbols:

The Agent is Wild. He replaces all regular icons and bestows a payout of up to 40x the stake on you. This character is also the Scatter, so you can trigger free spins round when you have three or more images of him on the screen.

Such an approach to bonus launch makes Agent 51 one of the releases in the Book of Ra series. Although, first releases were inspired by Ancient Egypt and a unique book was a part of the paytable, this genre evolves and now offers a diversity of themes. Investigation of alien arrival is one of them.

Regular Payouts:

• Four different alien creatures give you a payout of anywhere between 6x and 40x the bet.
• Footprints left by aliens pay up to 1.5x the stake.

BONUSES & OTHER WINNING OPPORTUNITIES

• K-Loops is a unique bonus that you will not find in other Book of Ra slots. The grid is full of accumulation symbols (low-paying icons). They are collected and added to the special Collection Meter when a camera lands on the grid. These symbols can appear with 2x or 3x multipliers. The climax happens after every tenth spin. All collected symbols expand on the grid and create a winning combination in any order. Such a combination pays in any direction.
• Three images of the agent trigger the free spins round. One of the symbols is randomly selected, and it becomes a special Expanding icon. This happens before every rotation. Extra free spins can be won.
• HyperBonus is available all the time. It gives you an opportunity to trigger 8, 10, or 12 free spins for a certain price. This feature allows you to start playing the bonus whenever it is convenient for you.
