is there a way to see which items can be combo'd together?
like, sometimes i "win" even if the items that i have in a row are different rather than all the same
yes, i have never fully understood slot machines.
Symbols connect by color. This isn't like regular slot machines so your confusion is understandable
Some symbols have 2 colors. There's only 5 colors, identifiable if you look at your reels (upper right corner button)
During battle, the lines between the matching symbols have the color that they all have in common
