Quoted from Zora:I would be interested in the blue arrow indication as well. Yes, it flashes during MB to indicate double and triple jackpots. But it is flashing blue in one ball play as well, sometimes The inner loop and sometimes the chest shot. I have no idea what the pin wants me to tell.
On the standard, the blue arrow represents the next constellation shot since it doesn't have a star map. I'm not sure if it does the same on the LE/CE.
