Serial Review

A brutal serial killer is on the loose in Limitless City, and dismembering victims with a rusty chainsaw while filming the whole thing has given him the nickname Bodycam Butcher. NoLimit City has clearly been inspired by the legendary horror classic, The Texas Chainsaw Massacre, when they created this character, and he looks bizarre and scary enough to match Leatherface himself.

We got Mental vibes from the dark and creepy bathroom that contains the base game, and it’s a gory crime scene accompanied by a dark metal soundtrack. You get an exciting sticky winning symbol respins feature that’s brand new, and each respin opens up an Enhancer Cell modifier. The Chase and The Kill bonus rounds are somewhat similar, but you also get a brand new xBizarre way to crack the 74,800x win cap.

Serial Slot Features

The xBet can be turned on/off between base game spins, and it costs 20 % more per spin to keep it on. This guarantees a scatter on the second reel per spin, which doubles your bonus round chances. The premium character symbols pay between 1 and 5 x your stake for 5 of a kind wins, with the Bodycam Butcher as the top-tier symbol. You get different wild features as well, and their primary function is to step in for pay symbols.

Winning symbols are frozen in place on the grid, and the remaining positions respin. You get new respins as long as you improve the current win, and one enhancer cell on the top row is opened up per respin from left to right. This provides the following randomly assigned Enhancer Cell modifiers:

• xWays - packs 2 to 4 matching pay symbols, and all present instances reveal the same randomly chosen matching symbol.
• xNudge Wild - is a wild symbol that nudges in place to cover the full reel, and each nudge increases the wild multiplier by +1. You can get these on reels 2 to 4 outside of enhancer cells as well.
• Wild - is a regular wild symbol that substitutes for pay symbols.
• Character - awards one of the premium character symbols.

You can land the xSplit Wild on the rightmost reel only, and it splits all symbols on the same row to the left in two. Also scatters are split in two this way, and this doubles the number of free spins they contain. The xNudge multiplier doubles if split, and the number of symbols contained in the xWays symbol is also doubled if they split. Infectious xWays spreads to all matching regular sized symbols on the main grid, so they contain the same number of symbols per position.

The Search Bonus Round triggers from 3 scatters (1 in 240 spins hit rate (or 1 in 120 with xBet on)), and each scatter comes with a value that amounts to the number of free spins you get. You get extra Enhancer Cells added to the 3 middle reels, giving you a 3-5-5-5-5-3 grid. You upgrade the feature to The Kill if an xSplit symbol lands (1 in 31 features hit rate), and this awards +2 extra spins as well.

The Kill Bonus Round can also trigger directly from the base game, and you need 3 scatters plus 1 xSplit symbol in view to get it. It plays out pretty similarly to The Search feature, but you always get an xSplit Wild present on reel 5 during this tier of the bonus round. It can move to different positions on reel 5, and it does its thing on each spin.

The overall max win is 74,800x your stake in Serial, but only up to 18,700x your stake is possible in the base game or the bonus rounds. If you hit this win cap, you trigger the xBizarre bonus game. It’s a 50/50 chance gamble in 3 levels, and you crack the 74,800x potential if you make 3 correct picks. The good news is that you get to keep your achieved winnings if you make an incorrect pick.

A Bonus Buy feature has been included, as usual, but it’s not available in the UK for sure. You can get The Search for 78x your stake (96.27 % RTP), and The Kill for 480x your stake (96.38 % RTP). The Lucky Draw option costs 279x your stake, and it gives you a 30 % chance of getting The Kill (96.38 % RTP).

The 200 Spins Serial Slot Experience

You get a brief taste of the base game, before we purchase The Search feature at 0:35 into the 5:17-minute highlights video. We buy The Kill bonus round right after, and it triggers around 2:12 into the video. You can see for yourself how it all played out by hitting the play button below.

Review Summary

It’s hard to imagine the shock effect a game like Serial would create if it was a unique one-off from an otherwise tame developer. However, players familiar with NoLimit City are bound to become somewhat numb to all the bizarre and grotesque themes by now, and Mental came across as more gut-wrenching than this, to be honest. Don’t get us wrong though, as Serial is definitely a high quality release that cuts through your mind like a bonesaw.

Having sticky winning symbol respins open up enhancer cell modifiers is a stroke of genius, but you kind of feel like you’re drowning in slicing and dicing with so much nasty stuff going on at the same time. The xBizarre feature is a brand new twist as well, and you have a 1 in 12m chance at hitting the 18,700x soft cap from the base game to trigger it. The 74,800x win cap comes with a 1 in 265K probability in The Search bonus, and 1 in 16K in the The Kill feature.

If you enjoy Serial Slot you should also try:

Mental - is the creepy asylum installment that truly established NoLimit City in a controversy league of their own. It comes with a 3-2-3-2-3 grid, and you get so much cutting, slicing and bizarre features that it’s pointless trying to sum it up here. Dead patient multipliers up to x9,999 is a highlight though, and 6 enhancer cell modifiers will benefit you as well. There are 3 bonus round tiers, and the 66,666x potential fits the bill.

Karen Maneater - is another extreme volatility installment in the bizarre genre from NoLimit City, and it revolves around a fast food restaurant that serves, well, “exotic” meat. You get both infectious xWays and xWilds in this post-apocalyptic release, and the sticky xWays bonus round comes with 2 tiers and a 11,757x potential. The base game win cap probability is a solid 1 in 330K.

The Rave - comes with one of the coolest and most insane big win stories ever from NoLimit City, and that is saying something. This is a drug-fuelled psychedelic trip to say the least, and it comes packed with xMechanics and enhancer cells that are persistent in all 3 levels of the bonus round. The max win is 41,500x your stake, and you might recognize the DJ if you take a closer look.
