Only green bubble...

There is no such level ;)

Each time there is a level with a unique color it will be red. In fact there is a kind of hierarchy in the colors, a one color level will be red, a level with 2 colors will be red and blue, a level with 3 colors will be red, blue and yellow (if I remember well), then for 4 colors it adds green and finally purple for 5 color levels.

Hi @sarma_palash123 level 1075 is all green bubbles if that helps :)
