Sand Castle

No tricks! A little dexterity is required - pushing, dropping, and catching the bot. The "bot shift" effect is used.

Very cool and attractive design. Unique use of bot shift. Amazing logical gameplay. I really enjoyed it.I really liked B's shift from slider to rail.
I've seen the slider to rail shift in some of your previous levels, but it always confuse me.

@Kanchan yadav I'm really glad you liked everything, both the design and the gameplay (I really tried to make both appealing).
Regarding the rail and slider, this is one of my ways to replace the "low ceiling," meaning making the passage only in one direction. There's a second way with a wedge above the slider—originally, this level had a second way with a wedge. But due to the design, I decided the "rail and slider" would look better.

Thank you SO MUCH my friend

Did not quickly see the way to get back on top. You constructed a weird elevator. At the ens I used SSS, but then thought that was not correct. With R already on B, I pushed R off B getting the bots back in the wrong order. Then I did as it intended. Wonderful puzzle.
