The days of simple three-reel fruit machines with a single payline are practically ancient history in the modern casino industry.

Software developers are in a constant arms race to invent the next big mechanic that will captivate millions of players.

How Megaways Slots Changed the Industry

The single most important innovation of the last decade was the invention of the 'Megaways' engine by Big Time Gaming.

Because the reels can hold anywhere from two to seven symbols per spin, every round feels completely unique and unpredictable.

• You do not need symbols to line up perfectly; they just need to appear anywhere on adjacent reels from left to right
• The engine was so successful that Big Time Gaming now licenses it out to almost every other major software provider
• A tracker at the top of the screen constantly calculates exactly how many 'Megaways' are active on the current spin

Exploring Cascading Symbols and the Bonus Buy Feature

This allows you to chain together multiple sequential wins on a single spin, creating massive momentum.

Furthermore, many modern slots now include a highly controversial 'Bonus Buy' or 'Feature Drop' button.

The modern slot machine is an absolute masterpiece of mathematical engineering designed to maximize adrenaline.
