Katrielle and the Millionaires' Conspiracy walkthrough
Puzzle Location: The Lucky Clover (The desk in the center)
To make some items of jewellery, this girl needs various pieces of cord, each with one red bead on them.
Using a special cutter that cuts in a circular shape, get the lengths of cord ready with just one cut.
The cord is not joined up anywhere you can't see.
Slide the circle to move it to the place where the cutter needs to be used.
The cord cut off inside the circle is not required.
There are some lengths of cord with just one bead and some lengths of cord with two beads.
The first thing you need to do is figure out which ones contain two beads.
There are three lengths of cord that have two beads.
Figure out where to place the cutter so that all three cords are cut at the same time.
Continuing on from hint two...
There is a place where all three lengths of cord join.
The bottom-left area looks promising.
Continuing on from hint three...
There is a place in the bottom-left area where the three cords are joined in the shape of a triangle.
That is the place to cut.
The answer is as follows.
