Six blocks in
level 3
In level 4 you only have four different blocks, but it’s the selec-
tion of the most difficult blocks that usually have to be rotated
in order to be optimally stacked. Level 4 is therefore even more
difficult than level 5, where you always get simple blocks to fill
gaps. In level 4, the simultaneous rotation and position change
is practiced particularly effectively, whereby it is useful to slowly
increase the speed.
