Mental x9,999 Features

Employing a host of regular and innovative features, Mental x9,999 is packed with an intense number of functions and bonuses. Somehow, NoLimit City manages to make it all work, with most of the slot’s key elements featuring in both the base game and free spins. Speaking of which, the slot’s Free Spins bonus is split into 3 distinct iterations, each delivering a unique twist on the bonus rounds.

Fire Frames

Triggered at random, Fire Frames will target up to 13 positions on the reel and split their respective symbols in two, doubling your winning opportunities.

Dead Patient

You’ll meet a host of patients in Mental x9,999, each suffering from a variety of garish ailments. The horrors inflicted on these souls eventually leads us to the Dead Patient symbol. You will need to land 2 of these morbid symbols to trigger the Dead Patient Multiplier that can range from 5x to 9,999x your current bet.

Enhancer Cells

As one of NoLimit City’s signature mechanics, Enhancer Cells make an appearance here as well. Whenever 4 or 6 Fire Frames appear on the reels, players are gifted with Enhancer Cells. These cells add booster symbols to your reels in the hopes of improving your odds of winning, including the likes of xWays, xNudge and xSplit.

Mental Transform

As part of their depraved experiments, the staff at Mental x9,999’s institution have their very own reserve of Spider symbols. Whenever one of these eight-legged creeps lands on your reels, your symbols will transform.

Mental x9,999 Free Spins and Bonus

Perhaps the slot’s most intriguing of features, Mental x9,999’s Free Spins bonus comes in 3 unique variations. Each variety is unlocked through a different combination of symbols and offers a different gameplay experience.

Autopsy Free Spins are the regular bonus rounds that you can unlock by landing 3 Scorpion Scatter symbols on the reels. It’s the most basic iteration of the bonus reels, with the Sticky Fire Frames being the only major gameplay modifier.

Lobotomy Free Spins are activated by combining the 3 Scorpion Scatter symbols with 1 Spider symbol. The Spider symbol remains sticky throughout the bonus rounds, guaranteeing a Mental Transform on each spin. A Dead Patient Multiplier is also included and transfers to any Patient symbols that land.

Mental Free Spins are the slot’s top bonus set. Triggered by landing 3 Scorpion Scatters with 2 Spider symbols, this bonus includes all of the previous versions’ perks while also maintaining a Dead Patient Multiplier that never resets.

Mental x9,999 Theme and Symbols

Perhaps the most prominent conversation around Mental x9,999 rests with its very disturbing theme. The slot seems to be set in some sort of questionable institution that carries out horrifying experiments on its patients. NoLimit City is known for tackling quite dark and sinister themes, but this feels like uncharted territory – even for them.

The quality of the presentation is on point, but the subject matter itself is quite hard to look at. Symbols display various human organs and a series of patients that have been subject to some form of torture. The slot presents all of this in a very realistic style, so the grim visuals are even harder to bear. So, while the direction that provider went with for the slot can be commended on an artistic and creative level, it feels like it’s stepped into a very dark place – one which may be too much for some players.

Mental x9,999 RTP & Volatility

With volatility cranked to the maximum setting, players shouldn’t expect to see a whole lot of successive wins, but when the slot finally pays out, the win will be worth the wait. RTP stands at 96.06%, a decent enough value which stands on par with similar slots.

How to Play Mental x9,999

Played on 5 reels and 3 rows, Mental x9,999 offers over 108 paylines to win from. To play, simply select your bet amount and press the Spin button. An autoplay function has also been included.

Slotsia’s Review

Mental x9,999 is another great entry for NoLimit City. Its long list of comprehensive features works well to create an engaging experience. On the other hand, the slot’s contentious theme and visuals could be a big deterrent for some players. Either way, this is certainly a different type of slot and we enjoyed reviewing it.
