- First = Square = Move the black circle in all 4 corners then tap the green button on the lower left.
- Second = Triangle = Top middle, lower left, lower right.
- Third = Diamond = Top middle, middle left, middle right, bottom middle.
- Fourth = Short triangle = Top middle, middle left, middle right.
