Hi there. I have finally come across a level that just proves my point that not every player gets the same board, even though it may look the same. Check out level 854. It only has 11 moves. Ridiculous, right?
How can anyone possibly pass this in 11 moves? Of course, only if you can get one of the UFOs with your first few moves. But can you? Can a skilled player do this? I dare say no: You just need to wait for the game to let you pass. You need to spot a lucky board and then take advantage of it. How long it takes for one to come up, now that is up to King and they change this every week. This week it took me so long, I was offered a whopping 100 extra moves for 10gold! Other weeks, it'll be on your second try I reckon.
This is how I got there, with my lucky board:
That was my starting board, looks good. Could this be THE ONE?
A few more moves and I've freed the UFO. And whoosh.....
One turn later and I know this really IS the ONE.
So I rest my case: You will pass when the game lets you pass. Nothing to do with skill. Nor with luck. It's all predetermined by whatever algorithm you are assigned to.
