Spoiler: Trick List B: - low ceiling (push B up on a wedge and the wedge above will cause B to act strangely and go where B can't normally go) R: - offset block (if a block is in the middle, R will become unstable and may jump off the end) Spoiler: Video Solution
Liked working out method of getting bots to the other side. My win similar although I didn’t use the prominent red brick block.
@ridgerunner - That is funny as the brick was your warning for R to get trapped but there wasn't a trap (anymore). So it's a red herring now. Thanks for P, C and R.
