Hexagon Lines

Make two of the same line.

Both are blue-blue-red-green.

3 or more colors are needed in one line.

As you get more cells at one time, the point value for each cell gets bigger.

6 cells:
6 points
8 cells:
16 points
10 cells:
30 points
12 cells:
48 points
14 cells:
70 points

Making the second line in reverse order is allowed.

The hint will be shown after 15 seconds of last getting the cells.

When no more cells can be got, all cells will be changed.
