Keep R Stable

I used only 1 zapper, as...

Spoiler

the slider filling the hole at an angle, with zapperbot on it, and a stack of two balls next to zapperbot

... works too. But this too required quite some thought.

@Block builder - Rotors have many purposes and I generally stay away from them. Glad you got it none the less. Thanks for commenting and rating.

@Block builder - I tried your method and I was able to get B and R across but I wasn't able to proceed. You are a super player!

| Very tricky logic level. I needed the video for the last steps as I thought B is going to win. I found the steps where you need place the balls on Zs original and really stable. I used the draggable instead of B to guide R and in turn guide Zs in place.

@laurence.gr - Good for you on completing this level - The feedback has been low but I didn't think it was that hard just different. Yes, B wasn't required to herd R but it's a little easier. Thanks for the comments and rating.

| @gmacpro - Yes, it's not that hard, only tricky and requires more time to understand the sequence and correct steps. I also didn't experience any significant instabilities with R.

Excellent level of logic!! Very challenging...Great job @gmacpro ,thanks for sharing
