(10 years ago) Splendid level! Only in 164th try did I ''move'' from 64 off to 14 off! Now, I'll keep searching! OMG, 10 off in 170 tries and NO more ideas! :S Edit: Yessssssssss - 174 tries, altogether. One of the best levels in the whole game, for me! Really tricky! :)
EDIT 2023, 14th July: second time around I got to 10 off in 39 tries. But now dry of ideas. I nevertheless hope to be able to clear it, again.
EDIT2 (about 12 hours later) : Got an idea and it worked. Still one of my favourite levels! :)))
