Serial has a setup that starts off with 5x3 reels and 243 ways to win, but there are many opportunities to get more out of it, once the xWays system expands the area. You can get a top prize of 74,800x the stake, but with very high volatility characterizing the action. The ones helping out are the game’s wilds, in regular, xSplit, or xNudge form, but also the xWays, respins, or the very powerful free spins.
On the reels, symbols include 5 crime scene objects including hard hats, shovels, gloves, chains (from a chainsaw) and butcher meat hooks. The higher value symbols include a human skeleton, scared lady, bloodied doctor, special agent and the Bodycam Butcher himself. The Bodycam Butcher is the best paying symbol with 0.5, 0.8 or 5 x your total bet awarded for 3, 4 or 5 in combination.
Look out for the xSplit Wild symbol which is a 2x wild and represented by a chainsaw. Landing only on reel 5 (the rightmost reel), the chainsaw xSplit Wild splits all symbols in the same row into 2 symbols.
The Serial slot comes with an xNudge Wild feature. A stacked wild symbol will always nudge to become fully visible. Every nudge sees the multiplier increase by 1. The xNudge Wild only lands on reels 2, 3 and 4 though. As mentioned above, an xSplit Wild can split the xNudge Wild which doubles the multiplier.
