One of the most popular slot innovations in the modern era is the introduction of the Megaways game mechanic. Prior to the invention of the Megaways game mechanic, online slot games mostly stuck to fixed play grids, with common releases featuring low payline counts. The introduction of the Megaways mechanic enabled dynamic play grids by varying the number of slot symbols per spin, usually between 2 and 7 in each reel.
Over the years, many slot games have adopted the Megaways mechanic, which can be played on UK online casino platforms. The Megaways slot mechanic was introduced in the Bonanza slot title, which was released by Big Time Gaming in 2016. After this release, the mechanic has become a notable feature in the iGaming industry, with numerous developers incorporating it.
Ancient Island Megaways
Notable slot development studio, Pragmatic Play, released the Ancient Island Megaways slot early in 2025, implementing the Megaways mechanic as well as other interesting bonus features. The developers have created a visually appealing slot game inspired by the Ancient Island Megaways, with a design that aligns with the Aztec theme. Like many Megaways slot releases, gameplay will take place across a 6-reel playgrid that has a maximum payline count of 117,649. Each of the reels in the Ancient Island Megaways slot will feature between 2 and 7 symbols in each spin, thanks to the implementation of the technological Megaways mechanic.

To add to the eerie aesthetic, Pragmatic Play has added glowing skull heads on either side of the playgrid, along with a full moon.
