xWays® unlocks unprecedented win potential for players. Usually seen in a fixed Ways game, any xWays symbols that land reveals a stack of the same symbol, increasing the ways available to win, and when working alongside some of the other mechanics available in this series, such as xNudge or xSplit, can pave the way for some huge wins.

xWays® first made an appearance in Pixies Vs Pirates, although many players will more likely recognise this mechanic from Punk Rocker, an early 2020 release. Alongside these two releases, xWays has made an appearance in a host of other NolimitCity games, including Dragon Tribe, East Coast vs West Coast, and San Quentin – the early 2021 release which rocked the community with news of a 150,000x maximum win availability.xSplit® was first made available within xWays Hoarder xSplit, released in July 2021. On this first occasion, xSplit symbols go a long way towards assisting wins through the feature, as any xSplit symbols in view to the right of a Scatter symbol will turn the Scatter into a Super Scatter symbol – which within this release assists in progressing the feature through several levels. However, aside from the progression through bonus levels, xSplit as individual symbols increase win ways during base play. Any xSplit symbol in view will split all symbols to the left of it into two, increasing the ways to win. After this, the xSplit symbols will turn into wilds – for the potential of huge wins.At an extra cost per spin, the player gets an increased chance of getting into the Bonus Modes. The way this happens varies from game to game. The payout for each symbol is not affected.xNudge®:  A simple yet effective feature that turns any game into a massive potential bearing title! xNudge works alongside wild reels, wherein landing a wild in view has the potential to increase the multiplier attached, as the wild nudges to fill the entire reel. If the wild is not centred in the reel, it will either nudge up or down, incrementing its multiplier by 1 for each nudge. Infectious xWays is the most widely misunderstood of the xSeries, with many players not understanding how this mechanic works. Often, players find the concept of Infectious xWays confusing. Still, this mechanic has now appeared in East Coast vs West Coast, and Infectious 5, wherein this was the only mechanic available, assisted only be original xWays. 
 
Despite seeming bewildering, Infectious xWays is actually very easy to understand – any xWays symbols that appear will reveal the same symbol, and if the symbol revealed is already visible on the reels, each in view will be ‘infected' and will expand as if they are xWays – producing additional ways to win.
 
 Whilst working alongside win multipliers, or linked reels within East Coast vs West Coast, this mechanic can be instrumental in producing life-changing wins.

Nolimit City has once again released an online slot that commands attention through its uncompromising presentation and razor-sharp execution. Clearly, serial killers aren't for all tastes, nor is a math model that can be as brutal as its masked main character. However, if you count yourself a fan of what Nolimit City does, then Serial should rock worlds up there with the rest of the studio's more memorable releases.

Like how the Professor in the La Casa de Papel is thinking through every little detail, Nolimit City shows the importance of each part playing a vital role and with the right composition, a masterpiece like this one can be created.

In summary, the Serial slot isn’t for the faint-hearted. The disturbing theme will spark controversy surely but Nolimit City are the masters of this. With 74,800 x bet max wins, the new xBizarre feature is the only way to achieve this as you hope to add 18,700 x bet wins for each successful gamble. There is no risk though so it’s more than welcome.

Many players surely wonder if this is the limit of creepiness and controversy for Nolimit City. Although, can black humor be constrained in any way since it's often a matter of interpretation? Undoubtedly there will be voices of disapproval and critique that say things spun out of control and went too far, as happened before with Tombstone R.I.P., for example. But the studio doesn't seem to care for those much, and it's apparent that nothing in their productions is accidental. Serial is a meticulously crafted parade of horror mixed with exciting features and incredible win potential. If you play the game for a good while, you'll notice how everything falls into place, with art going hand in hand with mechanics and being complemented by carefully paced audio. The choice of the theme is a question of preference, and there are hundreds of slots available with a much lighter approach, even in Nolimit's offer. But if it's the dark, edgy, and constantly tense atmosphere you're looking for, the abandoned bathroom awaits.
