Spoiler: Hint

Requires knowledge, but no tricks.

I seen your hint and that knowledge is required. The ball disappears and stuff moves but what is happening? I had no idea so I applied knowledge and removed the wall with MekoStudio to see what's hidden. After seeing what needed to be seen, I said 'Too simple now'.

EDIT - However, it wasn't as simple as it appeared as

Spoiler

B also needed to use the head to win the game.

Thanks

Jajaja,you fooled me for a while!! Very fun logic level with really nice design...At least you must...

Spoiler

use your head to solve it

Thanks for sharing and very well done @Don G Rowe

Spoiler: Shortcut

you say no tricks required, but you can actually ToA and skip 90% of the level. Get B on the grass behind where he starts, and you can ToA to the gray stone blocks that form that long row on the edge of the level. From there it's a simple walk to the win.

Otherwise I'm at a complete loss at the moment - it's obvious what that lowest ball does, but after that, no clue.

@D.S.Masters No ToA is required to win.

Spoiler

The lowest ball activates a mechanism that makes it possible for B to free PillR. Also the basis of the name.

I agree with @delator77, fooled for a while. That's so sneaky, because you have to watch the steps. And nice design.
Thanks @Don G Rowe!

Very good puzzle. The confusing element was that Pillar-R failed to tip the ball on the first attempt. The second attempt was successful.

The superficial simplicity combined with slight misdirection works well.

@Don G Rowe No, it's not needed, but I thought I'd let you know in case you wanted to remove it. As far as the level name, I figured that out when I saw what zapper does, but it doesn't get me any closer to freeing R.

The zapper raised up under the fence makes it walkable by both B and R. At least it does on my device ...

Very nice logic level. First ball, B and R-Pillar interaction was really cool.
Thanks!

This level is amazing, great logic,team work and very fun. Btw, nice hint

Very clever logic level with nice visual design

Nice one, enjoyed it. Although a bit frustating on the ball part
