Short rules: Normal Sudoku rules apply. A number in a circle is the geometric mean of the number in the wavy cell and the one- or two-digit number in the gray region each connected to the circle by a black line.

Longer rules with physics background: Normal Sudoku rules apply. An inductor is a cell with three half-waves (a “coil”) containing its inductance, L, as a digit. A capacitor is a gray region of one or two horizontally neighboring cells bounded by two black parallel bars; its capacitance, C, is given by the number it contains. For a two-cell capacitor, the capacitance is written as a two-digit number with the tens digit on the left and the ones digit on the right. A black line represents an electric wire. An assembly of an inductor and a capacitor connected by electric wires within a loop represents an LC circuit. The oscillation period, T, of an LC circuit is given by T = 2π Sqrt(LC), where Sqrt() is the square root operation. A circled cell on a wire contains the oscillation period T in units of 2π, i.e., Sqrt(LC), of the corresponding LC circuit.
