Mental slot Big Win August 2022

We've already seen many huge wins scored on the Mental slot, and it's no surprise casino hounds keep grinding for more. This time, a lucky player was able to win over half a million dollars on 4th of August. Playing with a bet of $8, he managed to trigger the free spins bonus, where branded Nolimit City features led him to the 66,666x max payout.

00:13

The player triggered the bonus and received 11 Mental Free Spins.

00:40

Not so long after the start, the player scored a huge winning combination thanks to xSplit and xWays features, which paid $9086.40.

01:15

Then, spins were not that fruitful, so the player didn't receive too much until the feature was about to end.

02:35

When there was only 1 spin left, another xSplit symbol landed, but this time paired with the massive multipliers, the combination resulted in an unbelievable $524,176 payout.

02:50

The win cap was reached and the player got away with a total prize of $533,328.

Mental Review

Last Update: 01.02.2022. Author: SlotCatalog.

NoLimit City keeps living up to the first part of their name again and again, and it will be interesting to see if they’ll ever attempt to top Mental when it comes to controversial and nasty themes. The asylum audiovisual presentation with sepia-toned symbols could hardly be more gut-wrenching and creepy. There is not even a hint of humor to be found here, like you get in most previous releases centered around a dark subject matter.

The complexity of this game is such that both reading about it, and watching it play out, is equally overwhelming. It’s gonna take a good while before you’ll be able to fully grasp what’s going on. The math model is rock solid as usual from this developer, and cracking the 66,666x potential comes with a disturbing amputation win cap story that’s already been censored in some markets. All in all, you’re in for a ride like nothing else out there in Mental, and burning the midnight oil might not be a good idea if you want to sleep well after.

Mental Slot Features

You will see that 1 to 13 positions are surrounded by flames in the base game, and these Fire Frames split symbols in two. The 5 patient premium symbols are worth 1.5 to 5 times your stake for 5-oak, while the low-value organ symbols pay 1 to 1.25 x your stake for 5 on a payline.

You trigger the Dead Patient feature when 2 Dead Patient symbols land, and one of them turns into a premium patient symbol with a multiplier of x5, x10, x15, x30, x50, x100, x300, x500, x1,000 or x9,999 attached. This equates to the number of symbols, so it’s not a regular win multiplier.

Reel 2 and 4 come with Enhancer Cells at the bottom position, and these are activated by 4 or 6 Fire Frames, respectively. Once triggered, the Enhancer Cells award 1 of 6 modifiers:

  • A simple wild symbol.
  • 1 of the 5 patient premium symbols.
  • A Dead Patient symbol.
  • xWays reveals 3 matching symbols (not scorpion, spider or dead patients).
  • xSplit splits a symbol on each reel in two, and splits itself into 2 wilds.
  • xNudge Wild nudges in place to become fully visible on the reel, and each nudge increases the win multiplier by +1.

The Mental Transform feature is triggered when you land spider symbols on reel 2 or 4, and these turn into an xSplit, xWays, Wild, Dead Patient or Patient premium symbol.

You win 8 Autopsy Free Spins when you land 3 Scorpion scatters on reels 1, 3 and 5, and each scatter landing in a Fire Frame awards +1 extra spin. Up to 5 random positions are upgraded with a Fire Frame, and these become sticky for the duration of the bonus round. The feature can be upgraded to both the Lobotomy round and the Mental round.

The Lobotomy Free Spins is triggered when you land 3 scorpion scatters together with 1 spider scatter. This awards 9 Lobotomy Spins, and the feature builds on the rules of the lower-tier Autopsy feature. In addition, all Spider symbols that land become sticky, triggering the Mental Transform feature on each spin. The highest multiplier from Dead Symbols is collected, and applied to any new Patient-symbol. You upgrade to the top-tier Mental bonus round by landing 2 spider symbols.

The Mental Freespins feature is triggered from the base game if you land 3 scorpion scatters and 2 spider scatters on the same spin. This awards 10 Mental Spins, and the ‘Mental Transform’ Spider symbol is sticky also here. The Dead Multiplier count does not decrease by 1 when transferred to a new patient symbol, like in the previous tier.

Non-UK players (if eligible in your jurisdiction) can take advantage of the Bonus Buy options as follows:

  • 8 to 11 Autopsy Spins cost 80x your stake (96.26 % RTP). Base game hit rate is 1 in 220 spins. Max win chance is 1 in 950,000. Upgrade to Lobotomy/Mental chance is 1/10.
  • 9 to 13 Lobotomy Spins cost 200x your stake (96.17 % RTP). Base game hit rate is 1 in 9,400 spins. Max win chance is 1 in 9.4 million. Upgrade to Mental chance is 1/25.
  • 10 to 15 Mental Spins cost 1,000x your stake (96.68 % RTP). Base game hit rate is 1 in 100,000 spins. Max win chance is 1 in 1.25 million.

The max win scenario, which involves the amputation of an arm (not all jurisdictions), is called the ‘This is Mental’ feature. It occurs if you hit the 66,666x potential, which is the hard-capped max win in this game.

The 200 Spins Mental Slot Experience

We have a jam-packed 8 and a half minute highlights video lined up for you this time, and we basically purchase all 3 bonus round tiers in chronological order. We’ve involved a bit of base game play also, and the bonus round cavalcade starts around 0:30. Hit the play button, lean back and enjoy the show!

Review Summary

You can seriously go ‘mental’ trying to wrap your head around everything that goes on when this thing fires on all cylinders (or even only 50 % for that matter). Mental is the most complex, convoluted and disturbing release in the history of online slots, which is a feat in and of itself. The visual presentation is excellent, but horrific at the same time, and everything is accompanied by a haunting soundtrack that will make your skin crawl.

Patient-1 is a dead ringer for Hannibal Lecter with the face mask, and it would take something like a branded Silence of the Lambs release to top this experience. Keep some lighthearted fruit slot handy though, as you will need to clear your head after even shorter sessions in Mental. On the brighter side, the very solid 66,666x potential comes with an exceptional overall 1 in 18 million win chance, and per usual with NoLimit City, you really feel the horsepower immediately when testing the demo.

Pros

  • Up to 13 Fire Frames split symbols per spin
  • Dead Patient symbol multiplier up to x9,999
  • Enhancer Cells w/ 6 modifiers
  • 3 bonus round levels
  • Win up to 66,666x your stake

Cons

  • Beware of adjustable RTP ranges
  • A bit overwhelming in more than one way

If you enjoy Mental Slot you should also try:

xWays Hoarder xSplit - comes with a post-apocalyptic theme, and you will benefit from up to 95,760 win ways in this NoLimit City release. The xSplit Wild combines well with the xWays symbols on the 3 middle reels, and these merge in the 4-tier bonus round that can lead to 11,030x payouts.

San Quentin xWays - is another extremely volatile NoLimit City release, and the prison theme is almost as disturbing as the game at hand. Enhancer Cells trigger xWays Mystery and Razor Split symbols, and the Lockdown bonus round comes with an eye-popping 150,000x potential.

Fire in the Hole xBomb - is a highly explosive and volatile mining slot from NoLimit City, and the roughneck dwarf is basically digging for his long lost case of brew. You unlock bottom rows via cascading wins, and xBomb Wilds explode symbols and increase the multiplier. The hold-and-win style bonus round comes with 6 modifiers, and you can win up to 60,000x your stake.

Mental 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 Mental, we are using formula:

APL i = (7i + (284i - 2i) * 151 i) / 284i = 149.961

Where:
284 - quantity of valuable casinos with high weight in the United Kingdom. (Each casino gets weight. Casino weight is relevant to estimation of Internet traffic)
7 - Summa of positions in the casinos lobby
2 - 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 = 729.086i + (13.321 / 5000)i + ((0.1 * 18870)i / (5000 * 36500)i) = 29.501

SlotRank - is position in the game list sorted by SlotRank Value. Points that Mental gets for positioning in lobby:
729.086 = 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.
Maximum possible quantity of points gets game that top positions in casinos with higher CRV.
