The Megacluster engine was developed by a very popular provider – Big Time Gaming, and it has completely changed the way slots are played. The way Megacluster works is that you start with a regular 4×4 grid, a cluster-pays format, and a somewhat limited win potential. The overall gameplay is fairly simple: to form a win, you need to land horizontal or vertical clusters of 5 or more matching symbols. These symbols, however, are not like in regular slots, because if you land a winning combo with them, these will split into smaller pieces. So, for example, if you collect 5 symbols, they will break down into 4 smaller pieces per one symbol.
That is how the Megacluster engine works – you essentially get pretty much the same mechanics as in cluster slots, but here the symbols remain intact, while in Megacluster slots the symbols will break down into smaller pieces.
What’s more, in Megacluster slots, the grid will also expand, so if you start with the 4x4 grid, then the symbols will split up, and the grid needs to make room for more symbols. So now, instead of 4x4, you will get an 8x8 grid, for instance.
