Keep plodding along, Pianoplayer! I've been playing for 396 hours, and for about the last half have been looking for the Golden Berries--not that I knew what I was looking for until recently when I couldn't stand not knowing the 6th plant any longer. I've used none of the great aids others have developed, being a bit stubborn, but built my own grids and have been slowly filling them in. I was about to succumb and start breeding just for the GB's, but meanwhile continued to cross plants more or less systematically--and lo! I just crossed two and got the Berries!

OTOH, if you really can't stand it any more, Algorithm's "primer" above is wonderful--I didn't see it till I came here to brag (glad I didn't or I'd surely have "cheated"). It really simplifies figuring out the breeding.

Woohoo, just one _bug_ and one flower left to find!
