Stack III

Unfortunately, there is some issues in this level : sometimes R fall off from B. Move slowly then.

When I opened this level between lunch break, i tried and realised, it need concentrated time to finish, will give another try in evening.

I first had to think it was possible. Then I saw the idea and nearly finished... but some bot fell.
Will try again later, like @Pratik Bhalerao

Hard.

Yeah, this one really has tough timing.

I lost Rs many time. Would try another level.

Did it !!

Spoiler: Timing issues

For me, the only problem of timing is the first step : to make the first R go upstairs on 2nd floor. I realized that if you DON'T interfere with the bots and go quickly under a special hole, the two Rs are naturally synchronized so that you can raise up the 1st floor - when everyone is under a hole.

Hard BUT possible.
Thx 4 sharing !

The level logic is great! I like. But there is one problem 3 bots on top of each other are not very stable. I had to finish the level 5 times. The most offensive thing is when the top bot fell on the descent from the last step before winning a block. In general, only on the fifth attempt I brought R to victory. The hardest part for me was to finish with three unstable bots. But I really liked the logic of the level - that's why it's 5!
