There's definitely an element of luck with this one that means strategy only goes so far.
Yeah, this is the one thing that's soured me on this challenge somewhat. I, uhh, obviously can't go into specifics, but I'm going to try and talk obliquely by referencing your score - having crunched the numbers, I know what my chances of being able to beat it are, in theory at least, and it's not exactly
likely. I'm not saying that your score's put me off, mind! It's more like you say - strategy only goes so far here, so that even if I nail everything under my control, my final score will be decided entirely by the game's RNG...
...so, I guess I'm just going to have to do my best in the main while keeping my fingers crossed... which might make using my mouse a bit tricky, but ho hum...
