This is a repost as @ridgerunner and @Meko Guy found the alternative way. I added some part and win block. Spoiler: Video Solution
I am confused - not that B walked over the zapper but to think you are saying NO TRICKS. If B walks over a zapper (like in the video) then that is a trick - right? I didn't do that though. I got Z to push the ball which stops in between the two blocks. Z then herc pushes the mech and the ball falls. P comes, B walks over the ball to P and they go to the win.
Unstable in the extreme. I thought I must be doing something wrong until I saw your video. My PillR always nudges the ball just enough at the 1:15 point so it`s out of reach when he needs to push it forward at 1:41 ... so stuck. Not to mention that it`s nearly impossible to keep ZapR stable enough to do his part. And just so you know, that zapper pass B has to do off of the wedge block is totally a trick.
@Don G Rowe @Meko Guy Wha ?? That's a trick? Sorry I found out too late. I can change the description
Spoiler: Z Stable Relase the ball before Z pass it. Spoiler: Trick Requires tap on P when he stand beside Z
