> Three tiles can be flipped together

How do you make that happen? I haven't stumbled on that yet. I did discover, after playing for some time, that I don't have to swap adjacent tiles.

I guess @rrobukef means if you flip A and B repeatedly, they just swap positions and reverse orientation each time.

But if you flip A and B, then B and C, then A and C, you get B and C to swap positions without changing their orientations.
