Michael Madden · April 2026

Megaways is a slot mechanic invented by Big Time Gaming (BTG) that creates a variable number of symbols on each reel with every spin, generating up to 117,649 ways to win. The mechanic has been licensed to dozens of other providers and is one of the most popular in UK online slots.

How Megaways Works

In a standard Megaways slot with 6 reels, each reel can show between 2 and 7 symbols per spin. The number of ways to win equals the product of symbols showing on each reel — when all six reels show 7 symbols each, that is 7×7×7×7×7×7 = 117,649 ways. The number changes with every spin, creating dynamic volatility.

Best Megaways Slots

Bonanza Megaways (BTG, 96% RTP, 50,000x max win) remains the genre benchmark. White Rabbit Megaways (BTG, 97.39% RTP) is exceptional for its high RTP. Extra Chilli Megaways (BTG, 96.17%) introduced the Ante Bet feature that increases bonus frequency. From other providers: Fishin' Frenzy Megaways (Blueprint, 96.72%) and Big Bass Megaways (Pragmatic, 96.47%) are consistently strong.

Megaways and Wagering Requirements

Megaways slots typically sit in the high volatility category, which makes them suboptimal for clearing wagering requirements. For bonus play, low-to-medium volatility slots with high RTP are more efficient. Save Megaways for genuine free play or post-wagering sessions.
