Agent 51 Slot Features

Apart from a cool free spins feature, Agent 51 also has a unique feature called the “K-Loops” feature. This is the first feature we will be talking about because there is a good chance that you might like it! You can also buy free spins and skip straight to the free spins round in Agent 51 slot thanks to the Hyperbonus feature.


This feature is active during the base game. It works as a loop of 10 spins. After 10 spins are over the loop repeats itself.

During the first 9 spins you can collect different symbols. Once you collect a particular symbol you will notice that that symbol is marked with a color around it above the reels.

All these symbols that you collect during the first 9 spins become special symbols during the 10th spin. After the 10th spin, the feature rests and the loop begins afresh.

Hyperbonus feature

The Hyberbonus feature allows your to buy free spins and skip straight to the free spins round. You can find this feature on the bottom left corner of your game screen. 

In our opinion the cost to buy the free spins in Agent 51 is pretty low compared to most other slots we encountered where it can cost 100x to 200x to purchase 10 free spins. 

We have mentioned the price list to buy free spins in Agent 51:

  • 8 Free spins cost 45.36x your bet amount
  • 10 Free spins cost 63.92x your bet amount
  • 12 Free spins cost 85.30x your bet amount

Agent 51 Free Spins

If you manage to land at least 3 scatters on your reels during a spin, you can trigger the free spins round with 8 free spins.

During the free spins round a symbol is randomly picked by the game and acts a special expanding symbol.

You can also collect something called “assimilation symbols”. These symbols look like an old photo camera and come with multipliers of 2x or 3x.

When this symbol lands on your reels  any other symbol is chosen as the special expanding symbol for the rest of the 10 free spins. Then when you get that special expanding symbol on the reels it expands to the full size of the reel.

There is also the possibility to earn extra free spins. A symbol in the shape of a UFO gives you 2 extra free spins.

Agent 51 Slot Review Conclusion and Rating

Agent 51 is a refreshingly new slot with an intriguing new theme, game mechanics and features. Although the potential payout pales in comparison to many of the slots out there it is still pretty decent. The cost to buy free spins is low compared to a lot of slots out there that give you the choice to buy free spins in our experience which earns this slot by Kalamba our respect.

What really won us over was the K-loops feature which makes this slot a really fun slot to pay.

We give Agent 51 a 4 out 5 rating and recommend you to check it out!
