Agent-51 slot Big Win February 2021

February, 22, turned out to be a big day for some lucky gambler who managed to win €1640 on the Agent 51 slot, playing with a bet of €0.5 per spin. Click on the video below to see how that Free Spins round ended up with a staggering 3,280x win.

00:30

It wasn’t some sort of a lengthy win sequence, but a one-hit win. Throughout the bonus game, numerous Accumulation symbols landed and turned symbols into Special Expanding ones, as well as UFO symbols awarded additional spins, yet nothing special happened until the last spin was reached.

03:20

The total win was only €39.90 when 5 instances of the top-paying premium symbol with a 2x Multiplier appeared on all 5 reels and awarded a win across all paylines. As a result, a Mega Win of €1,600 was achieved.

Agent 51 Review

Last Update: 29.03.2021. Author: SlotCatalog.

The base game plays out in Agent 51’s dimly lit office, and it looks something like Special Agent Mulder’s office in X-Files. The cartoon style visuals are nicely done, and fans of alien conspiracies will feel right at home. With a more balanced approach to the Book of ... genre, Kalamba has created a very enjoyable base game that peaks on every 10th spin.

While we’ve seen up to multiple expanding symbols in the base game before, it’s never been done quite like this. The downside of evenly distributing the Book of … mechanic however, is that the single spin max win is reduced to 1,600x. Multipliers can do something about that though, and this means that the potential for larger single spin payouts is present also in the base game.

Agent 51 Slot Features

The special agent is the wild symbol in this game, and he will step in for all regular pay symbols to help you form winning combos. The wild pays 80x your stake for 5 on a payline, same as the highest paying alien symbol. All the pay symbols are on display above the reels, and the Polaroid camera “accumulation symbol” highlights one random pay symbol whenever it lands.

The base game goes in so-called K-Loops, meaning that all the highlighted symbols above the reels become special expanding symbols every 10th spin. If the Polaroid accumulation symbol displays an already highlighted symbol, the symbol multiplier is increased with +1.

The expanding symbols don’t need to land adjacent to win when the 10th spin comes. However, you will need at least 2 premium symbols anywhere to create an expanding symbol win, or at least 3 low-value symbols anywhere. Several symbols can take turns expanding, and this can lead to larger base game payouts.

The Special Agent wild symbol serves double duty as a scatter, and 3 wild/scatters anywhere triggers the bonus round. A special expanding symbol will be chosen up front, Book of ... style, and the Polaroid Camera symbol can land to increase the number of chosen symbols as the free spins play out.

A UFO symbol can land to give you +2 free spins, and there is no upper limit as to how many spins you can get this way. Non-UK players can take advantage of the HyperBonus option, and simply purchase the bonus round at any time. There are 3 bonus buy options as follows:

  • 8 free spins with no multiplier costs 45.36x your stake.
  • 10 free spins with up to 3x multiplier costs 63.92x your stake.
  • 12 free spins with up to 6x multiplier costs 85.3x your stake.

The 200 Spins Agent 51 Slot Experience

You’ll first see a full 10 spins K-Loop as the video starts, and then we purchase the bonus round at the 1-minute mark. The highlights video goes on for 4 more minutes, and we went for the 10 free spins option with up to 3x multipliers. We got plenty of extra spins however, and managed to upgrade 2 premium symbols with a 2x multiplier. Check it all out by hitting the play button.

Review Summary

It’s refreshing whenever you get a Book of … mechanic title that avoids the whole ancient Egypt cliché. Kalamba has certainly managed that with Agent 51, and the Area 51 ET mystery theme sets the stage in an intriguing way. Elements are cleverly combined to make the base game fun here, and you always have the 10th spin with expanding symbols to look forward to around the nex corner.

The price you pay for expanding symbols also in the base game is acceptable in our view, as 1,600x without multipliers is not all that bad. The overall max win of 5,593x is more than solid enough, and a bit higher than the “standard” 5,000x. Most ‘book slots’ are all about the bonus round, and Agent 51 is a good alternative for those craving a more balanced experience.

Pros

  • 10 spin cycles with collected expanding symbols
  • Expanding symbols can build up multipliers
  • Bonus round with accumulating expanding symbols
  • Win up to 5,593x your stake

Cons

  • Single spin max win is “only” 1,600x with no multiplier

If you appreciate Agent 51 Slot you should also try:

Ali Baba's Luck - was the very first ‘book clone’ that allowed for expanding symbols also in the base game. Winning symbols get highlighted here, and can expand on the next spin. The highlighted symbols don’t reset in the bonus round however, and this can lead to payouts hovering above 5,000x your stake.

Visitors - is a fun alien/UFO slot from ELK Studios, and it comes with respins where 2 out of 3 reel modifiers are active. The bonus round comes with doubling frame multipliers up to 4,096x, and you can win as much as 10,000x your stake in this medium to high volatility title.

Eye of Horus - is a super-popular Reel Time slot where the symbol upgrade feature takes center stage. Wilds will expand, and symbols are upgraded in chronological order in the bonus round. Get to the highest upgrade tier, and win up to 10,000x your stake.

Agent 51 SlotRank Calculation

SlotRank - is the rank of the game popularity in the specific market. We are calculating SlotRank based on the gathered data from the online casinos. Daily our crawling system scans thousands of casino sites. From each casino sites we are getting list of games, lobbies screenshot, and list of games in the lobby. Important parameter of games popularity is average games position in the casinos lobby. To calculate Average position in the casinos lobby (APL) for Agent 51, we are using formula:

APL i = (0i + (282i - 0i) * 151 i) / 282i = 151

Where:
282 - quantity of valuable casinos with high weight in the United Kingdom. (Each casino gets weight. Casino weight is relevant to estimation of Internet traffic)
0 - Summa of positions in the casinos lobby
0 - Quantity of casinos that put game into the lobby
151 - We put size of casino lobby as 150 games. 151 - means that game is not in the lobby.

For the SlotRank calculation we are using SlotRank Value (SRV) parameter. SRV is sum of points that game gets for positions in the casinos lobby + points for presence in casinos + very minor value for game release date.

SRV i = 704.930i + (13.279 / 5000)i + ((0.1 * 18676)i / (5000 * 36500)i) = 0

SlotRank - is position in the game list sorted by SlotRank Value. Points that Agent 51 gets for positioning in lobby:
704.930 = SUM ((151- Lobby Position)* CRV)
CRV (Casino Rank Value). CRV - is casino weight coefficient from 0.1 to 1 that gets each casino according to their traffic estimation.
Lobby Position - position in the casino lobby. We are measuring position for TOP 150 games. Highest position means that game placed on top left position in the casino lobby.
