In brief
Megaclusters: cluster wins that make the grid grow denser
Megaclusters is a Big Time Gaming mechanic family built around cluster wins and symbol splitting. A normal cluster game removes winning symbols and drops new ones into the grid. Megaclusters goes further: winning symbols can split into smaller symbols, increasing board density.

This makes each successful cluster more important because it can create more positions for the next result.
How Megaclusters works
A group of matching symbols forms a cluster win. Those symbols are removed. The game then replaces them with smaller symbols or more positions, expanding the number of possible connections inside the same grid.
If new clusters form, the process repeats. In bonuses, the mechanic can combine with multipliers, larger grids or additional feature rules.
What it changes
Megaclusters changes the density of the board. It does not only ask whether a cluster lands; it asks how the grid evolves after the cluster.
This creates strong escalation. A weak sequence ends quickly. A strong sequence can turn the board into a much richer set of possible connections.

How it works
How Megaclusters works
Megaclusters starts with cluster wins, then makes the board denser. Winning symbols disappear and are replaced by smaller symbols, creating more positions for new clusters.
The mechanic turns one win into a possible chain of board growth and repeated cluster checks.
It is stronger than standard Cluster Pays because the grid itself changes after wins.
