4 Balls in a Row

Spoiler: Video Solution

@Block builder - You will note that the card is full size so your found work around works perfectly - thanks again

Awesome lvl thanks for sharing it 
Edit

Spoiler: the way back

The ball blocked by the slider made me think over and over about the way back..

@RZK - EDIT - I'm glad I gave you a challenge and thanks for playing, commenting and rating.

I liked it. There was one part i did differently.

Spoiler: Variation

instead of pushing the ball with B i nudged the ball with the slider that moves the full width of the level.

Very nice balls pushing level but I had an important difference...

Spoiler

the hole that had to be filled by two balls,I used the same move to both balls-your second one,B pushing the ball moving the slider

...but honestly I prefer your move... more cool... thanks for sharing @Meko Guy

Excellent level @Meko Guy, I liked how B, walked around this level, & the ball logic was challenging. The 2 ball hole was challenging, cos working out what 2balls had to go into it & when. Thanks for another fun level.

Really liked the logic behind this one and how the ball paths were visible. I was able to work through it without hints or VS. And that's quite a Triumph for me on your levels. LOL. Excellent challenge and thank you very much
