Clarification here - once you get to the single arrow, that’s the end of evolving
there’s not a single black check step where you’d need to combine two single arrows or anything like that
the game is to be the first to evolve into the single green higher arrow
So 64 is all you will need to get a single arrow. If it’s not green then you can try again but there’s some strategy ion combining color bands and Arrows that have the green arrow in it
