Serial Online Slot Review

Serial is an online slot from Nolimit City with a dark theme. A masked killer, his latest victim, and various torture implements are among the gruesome symbols seen across the 5 reels. Like many slots from this developer, a highly controversial topic mixes with a fantastic selection of extra features.

These include respins with extra ways to win, nudging wilds with multipliers, an enhanced symbol mix, and symbol transformations. You can also enjoy The Search and The Kill free spins features that play out on expanded reels and where wilds can remain active throughout.

It’s an extremely volatile slot with a return to players percentage of 96.07%. You can unmask the Serial slot machine on PCs, Android, iOS, or Windows mobiles to win up to 74,800x your stake at the best casino sites.

How to Play the Serial Slot Online

Those of a nervous disposition should look away now, as we are about to enter the lair of a killer, where you find meat hooks, bloody chains, gloves, and a skeleton. Characters include a pathologist, FBI agent, frightened young victim, and the killer wearing human skin for a mask.

This gory set of symbols sit within a dimly lit and blood-soaked bathroom, and accompanied by a rock tune soundtrack, punctuated by screams. Serial joins equally twisted games from Nolimit City such as Mental, and Punk Toilet at desktop and mobile casinos with our recommended Betting Apps.

The bet range runs from 0.20 to 100.00 on each spin. Tap the ‘$’ on the controls to see all 25 staking options. When choosing a bet level, you should be aware of the extreme volatility that can lead to several losing spins in a row, countered by high average prizes.

Play starts with 243 different ways to line symbols across a 5x3 grid for a win, starting from the left reel. The 3 dots button on the control panel opens a paytable with a list of symbol values at the current bet. The killer is worth the most, at 0.5x, 0.8x, and 5x the stake when he’s on 3, 4, or 5 reels.

Free Spins & Other Serial Slot Features

Enhancer cells, covered in crime scene tape, sit above and below each reel. Any win triggers a respin with the winning symbols locked in place and the cells opening one at a time to give you more ways to win. Special symbols will land in the cells –

xWays – These reveal from 2 -4 matched symbols, one above the other.

Wild – A wild symbol can substitute for others to complete combinations.

xNudge Wild – Wild nudge up or down to fill a reel, increasing a multiplier by 1x for each step taken.

Character – A high value character symbol can appear on the cell.

Respins continue for as long as you improve the triggering win, and you can activate all cells for 8,575 ways to win across a 5x7x7x7x5 symbol grid.

Wilds, and xNudge Wilds can also appear at random on any spin. Other features can trigger at any time, including the xSplit Wild chainsaw on the right-side reel, that will split all other symbols on the same row. xSplit Wilds can divide xNudge Wilds to double their multiplier.

Wanted poster scatter symbols can transform into xWays symbols. These reveal 2-4 matched symbols, as in the respins, while an Infectious xWays feature sees all visible examples of the transformed symbol expand to the same size.

The Wanted poster in 3 places on the middle reels will launch The Search free spins. Each poster holds a number of free games, and the round begins with Enhancer Cells open on reels 2, 3, and 4.

Three Wanted symbols, plus an xSplit Wild trigger The Kill free games round. You can also upgrade to this feature from The Search when an xSplit Wild lands. The xSplit Wild remains active throughout The Kill, splitting other symbols and doubling xNudge Wild values.

If any win reaches 18,700x the total bet, you can play an xBizzare game. There’s a 50/50 chance to double the win, then a 50/50 chance to add an additional 18,700x to the total. The best bit is that you can’t lose, only gain from this feature.
