An ostensibly solid electronic die presents visual and/or sound effects when in use. Unlike known electronic dice, the disclosed electronic die retains the weight, feel and ruggedness of conventional non-electronic dice. The die includes an outer shell defining its shape. Electronics for producing the effects are located inside the shell. The shell is preferably filled with potting material and sealed shut. The use of potting material is a unique aspect of the invention that represents a significant advance over known electronic dice. The potting material gives the inventive die added weight and safely encases the electronics. Using miniaturized electronics and batteries, the die can have physical dimensions and weight that are the same as or similar to a conventional hand-tossed gaming die.
