Fruit Party demo: clusters on a seven-by-seven field
Fruit Party fills a seven-by-seven grid and looks for clusters of matching symbols in contact with one another. Winning clusters pay and are removed, remaining symbols drop, new ones arrive from above, and the search repeats until a refill produces nothing. Random multipliers can land on the grid during a tumble sequence, and when the sequence resolves they are applied to the total.
The visual language is simple and the maths underneath is not. Cluster detection means the engine is looking for connected components, so the geometry of where symbols land matters as much as how many of them landed. That is a genuinely different problem from counting scatters, and it produces a different feel — more near misses, more sequences that almost continued.
The Fruit Party free play version here runs the same engine with virtual credits. It is a useful demo precisely because you can watch, spin by spin, how often a cluster fails by a single adjacency.
