The brief
Normal Sudoku rules apply: Each row, column, and box must contain a complete set of the digits 1-9. Arrows: Digits along the shaft of an arrow sum to the value shown in the attached circle. MOLECULES: Cells are either electrons or non-electrons. A cell containing a digit from 1-5 is an electron. Each atom (pink circle) contains electrons whose digits sum to 8. (Electrons can contain digits greater than 5.)
