Like most NLC games, Serial is bursting with bonus features, which I’m going to tell you about below:
Enhancer Cells
The Enhancer Cells feature is a bonus feature found in other popular NLC titles such as San Quentin xWays. It’s triggered when a respin is awarded. Enhancer Cells are at the top and bottom of the grid, and the police tape shown in the screenshot below opens up when they are unlocked/opened. When they do, 1 of the following symbols land:
xWays | Reveals 2-4 matching paying symbols. If more than 1 xWays symbol lands, all xWays symbols will reveal the same symbol. |
xNudge Wild | A stacked wild symbol that always nudges to cover entire reel. Every nudge sees the multiplier increase by 1. |
Wild | A regular Gas Canister Wild symbol lands. |
Character | One of the high-paying character symbols can land. |
The Search
Landing 3 Scatter Symbols triggers The Search feature. This bonus starts off with the number of spins that the 3 symbols have on them. Once in, extra Enhancer Cells on reels 2, 3 and 4 open up. This sees a 3x5x5x5x3 setup which gives you 1,125 ways to win. Hitting an xSplit symbol on this bonus activates The Kill spins bonus feature.
The Kill
3 Scatters and 1 xSplit Symbol triggers The Kill bonus, The rules of The Search apply during The Kill with an extra bonus of having an xSplit Wild always present on the last reel, though it can move down or up.
xNudge Wild
Here a stacked wild symbol will always nudge to become fully visible on the screen. Every nudge sees the multiplier increase by 1. The xNudge Wild only lands on reels 2, 3 and 4.
Infectious xWays
xWays symbols only appear in Enhancer Cells or can be transformed from a scatter. They reveal 2-4 symbols of the same kind and increase the number of ways to win. The revealed xWays symbol will infect all of the same normal-sized symbols on the 5×3 grid to expand to the same size.
xBizarre
Serial comes with an overall max win amount of 74,800 x the bet. However, the most winnable amount in the base or bonus round is 18,700 times your total bet. When this level is achieved, you have the chance to win the game's full potential via the xBizarre feature which is a gamble feature. Here there are up to 3 stages, where you make a 50/50 choice. Getting all of the choices correct awards you the 74,800x max win. However, if you get the choice wrong you still get to keep any previous winnings.
xBet
This feature is for players outside of the UK. It allows you to increase your chances of triggering one of the free spins bonus features. The cost is 20% more per spin, and you’re guaranteed a Missing Poster Scatter symbol on reel 2.
Nolimit Bonus
Again if you’re non-UK based you can buy your way to the bonus rounds, there are 3 options available:
- The Search - costs 78x the bet - RTP of 96.27%
- The Kill - costs 480x the bet - RTP of 96.38%
- Lucky Draw (which means a 70% of getting The Search or a 30% of landing The Kill) - costs 279x the bet - RTP of 96.38%.
