Katrielle and the Millionaires' Conspiracy walkthrough
Puzzle Location: Flower bed (The purple flowers in the back)
You need to make a gift box with flowers drawn on each side.
Use the flowery paper to make a net diagram of a cube with six adjoining sides.
Which squares of the paper do you need to use to include six different types of flower?
Touch each square to select, and touch again if you need to deselect.
There is only one of the blue pansies at the bottom-right, so this one definitely needs to be included.
Continuing on from hint one...
The tulip at the top-left is more than six squares away from the pansy, so that can't be used.
You need to use the tulip near the bottom.
Continuing on from hint two...
If you use the sunflower above the pansy, the sunflowers around the tulip will get in the way and you won't be able to join up, so you can't use the sunflower above the pansy.
To connect from the pansy to the other flowers, you need to use the cosmos next to it.
You're trying to make a net diagram of a cube, so you need to choose squares that will join together to make a box.
Be careful, because if you select the red rose beneath the sunflower, you won't be able to make a box.
The answer is as follows.
