Big Time Gaming (BTG) has revolutionised the online slots market with their innovative Megaways mechanic, offering players the chance to enjoy thousands of ways to win on every spin.

What Are BTG Megaways Slots?

Before delving into the chart-topping slots, it’s worth briefly revisiting what Megaways actually is.

Megaways slots usually come packed with features like cascading reels, free spins, multipliers, and bonus rounds. This makes gameplay far more dynamic compared to traditional slots and highly attractive, especially for fans of high volatility and enormous payout potential.
