- Quick slide – bots can pass thru lower blocks when a slid quickly

B:

- cancel tap
- auto pilot with low ceiling

R:
- If R is on stairs, R will not past a block with a rail underneath

Spoiler: Video Solution

As usual

Lots of interesting moves.

The interlocking draggables were a good feature although I autopiloted past the inaccessible block.

...
3 main balls
are rolling on unusual paths.

Not for me... the first ball, fine - but it's the AP after it that I can't get, tried numerous times; B just does not want to get over to the rails.

@D.S.Masters - The rail move can be hard on my PC too. For some reason, B will go easily on fences etc but not rails. Turns out, on this level B just needs to get on the first one which I can do fairly well. Thanks for trying and commenting.

Tricky challenge...Thanks for sharing & for the FUN @Meko Guy

@Meko Guy I got him up there once - and then he promptly fell off. So that slider lift combo in the first move... which part was built first? I'm guessing the lift and its one rail, then the slider, because a slider by itself doesn't have a rail in it, which would account for the 'broken' rail on the lift.

@D.S.Masters - B fell off because of low ceiling. If you tap the grass and don't raise the lift, you'll see where B ends up and it's not on the rail spot so you must do a cancel tap to stop on the rail.

Many cool moves. I like the name, it is Three in a Row, but Thr3e.
Nice logic, a bit tricky but I liked it. Thanks for sharing @Meko Guy!

Excellent!
I really enjoyed this level
and
I found a shortcut.

Spoiler: Shortcut

@Pink Axa - Nice shortcut. Any lift can bump B and where B lands can be a surprised and also very hard to protect from. Thanks for P, C and R.
