Pattern Question (Tower Bloxx Game)

Tower Bloxx is a game where you build towers of varying size (residential, commercial, industrial…). Blue towers can be built anywhere on the 5x5 grid, while red towers need a blue neighbor. Green towers need both a blue and red neighbor, while yellow towers need to be adjacent to all three other colors. The best scheme I can think of looks like this:

B Y R Y B
R G B G R
B Y R Y B
R G B G R
B Y R Y B

I’m sure there’s a better scheme, any help?

Y>G>R>B

Just thought I’d give this a bump…

I did find a slightly better scheme…

R Y B Y R
B G R G B
R Y B Y R
B G R Y B
R Y B Y R

Anybody have any optimization skillz they’d like to share? :slight_smile:
