I think it’s a gain, as you can level them all up to lvl 4, tho it takes a long time
Oo oki, ty!!
As enchanted said.
I would say L just because you had one already to level 4, and now you have to start over again, however it could be also a G because now you have more gecko's to level it up.
Ty guys, now I can build my army
Gain! You can easily level up your geckos.
What do you think?
