## DKM Pearls Help and Tutorial

The goal of the Pearls puzzle is to draw a single continuous non-intersecting loop that properly passes through all the "pearls". There are black and white pearls, each color having it's own constraints as to how the line must pass through them.

The rules are simple:

• The line must be continuous and non-intersecting and pass through all the pearls.
• White pearls must be traveled straight through, but the line must turn in the previous and/or next cell in its path.

• Black pearls must be turned upon, but the line must travel straight through the next and previous cells in its path.

Figure 1 below shows a simple 6x6 puzzle and Figure 2 shows its solution.

In Figure 3, there are two errors with the solution. The first is that the loop is not continuous and the second is that the line through the white pearl (marked with a red x) does not turn at either end. (It may turn at both ends but at least at one.)
In Figure 4, there are also two errors. The line does not pass through the white pearl (marked with x) and also the line above the black pearl does not travel straight through the cell above.
