Single path example
I am using a little trick to make using the "always under" trick easier. I erase all roads except for a single path starting outside the city and passing by the administrative building. There is no crossings. The buses have to go and return by the same path and so their bubbles have to pass under or over each other. So i start checking a bus at the cactus end of path as it makes the return, if it crosses over another i change to the new bus and so on. After 10 bubbles overlapping in different directions i can garantee i have a Leprechaun. Because there is a single path any bubble will cross every other bubble in its way from the cactus end to the out of the city end.
I thought about making such a road too. It will be a little too much work to do now (have to go to bed, gotta get up in 6 hours already), but I will definitely be doing this tomorrow! Will be so much easier to get those damn Clovers... CMONYALL 01:11, March 18, 2012 (UTC)
