Tertium tower is this form. Copared with primis tower, there is only one color on bottom layor (in pic it is yellow).
Bottom layor color has a larger space than primis tower. So tertium is easier to be set up.
Basically you should set up tertium tower. If it is a difficult situation to set up, alternatively you convert it to primis or quartus tower.
Tertium tower is also more possible to be three colors tower. So to make use maximumly of tertium, you pay attention to space linking puyos.
