Here is a sample of initial-values to be entered into the specified cells:

Instructions:   The grid above contains 42 cells which make up 13 complete hexagons.  Each hexagon has a * in its center.  Also, each hexagon must contain the digits 1 through 6 exactly once.  There are six partial-hexagons around the outer border.  Each must contain four unique numbers (no duplicates).  They have two X's along the border, one * on the border, and three *'s inside.  For example, cells 3,9,10,11 make up a partial-hexagon, as do cells 32,33,34,40.

You enter the initial cell numbers, given with the Snowflake to be solved, by clicking on an entry-box that is either above or below the cell-number in the cells.  You can use the "TAB" key to move from cell to cell, or you can simply click on the entry-box in the cell you want.  If you make a mistake, simple backspace over your entry to leave a blank entry-box.

When you are done entering the initial values, click on the "Submit" button.  You will either get a unique solution, or one of multiple solutions, or UNSOLVABLE, or an error message.  Use your browser's BACK button to return to the entry page.  If you get an error, try to correct it and Submit again.
