GroupingINT vs Grouping Repeating items

__Eugene__

Hello guys,

Im a bit confused about the difference between these two types of grouping games. For repeating item type games, it's often really helpful to make a chart, but for int games the explanation videos almost never include making a chart. How can you tell these game types apart? Whats the different between interchangeable items and repeating items, and how can you tell quickly if a chart a good idea or not?

Thanks!
