Bonus Mechanics

Modern online slots often feature more than the traditional five reels, with some even utilising hundreds of paylines or dynamic ways to win. These slots are inspired by traditional pub fruit machines, which appeared in pubs and arcades before transitioning to online casinos. They typically feature a simple setup and are played across three or five reels, with simple graphics and nostalgic sound effects. A prime example of this game type is Reel King, a beloved fruit machine slot that made a successful transition from physical pub machines to online slot sites. While NetEnt’s Gonzo’s Quest is considered a modern classic, purists often refer to classic slots as games like IGT’s Da Vinci Diamonds.

Megaways slots use a dynamic reel system, where the number of symbols on each reel changes with every spin, resulting in a varying number of paylines. With up to 117,649 ways to win on a single spin and a cost per spin starting as low as 10p, it is easy to see the appeal of this exciting Megaways mechanic. Games like Fishin’ Frenzy Megaways demonstrates how this innovative feature can be seamlessly integrated into popular UK online slots.
