Hi Lee Kun, Was it done using probability formula? If it is- then yeah this will work only for Wind-up key as other prizes have more tiles which you will have add up around. And Im guessing this is "rounded" since once add up it goes to 100.6 %. I am also checking if there is an instance when the Dragon jumps 2 fields or across in his last "spasm" ( or at least sometimes my Dragon got spasm and jumps completely different direction where he is heading too)- as was not really observing it that much. Well, I cannot really comment about this as I have not re-brushed my calculating probability tbh. so I trust this is correct. Yesterday I was trying to block dragon with parcel and I noticed he was moving Orange all over the board. He was moving the item though.
@ Raven- I also opted Carlin & Edron as you do not have to "fight" for your turn to get inside and also, got few keys already+ no wasted time:)
